Why Cloudways is the Perfect Managed Hosting for PHP Applications

The following is a sponsored blogpost by Cloudways


Developing an application is not the sole thing you should bank on. You must strive to find the best hosting solution to deploy that application also. The application’s speed is dependent on the hosting provider, that is why I always advise you to go for the best hosting solution to get the ultimate app performance.

Now a days, it is a big challenge to choose any web hosting, as each hosting has its own pros and cons which you must know, before considering it finally for the deployment. I don’t recommend shared hosting for PHP/Laravel based applications, because you always get lot of server hassles like downtime, hacking, 500 errors, lousy support and other problems that are part and parcel of shared hosting.

For PHP applications, you must focus on more technical aspects like caching, configs, databases, etc. because these are essential performance points for any vanilla or framework-based PHP application. Additionally, if the app focuses on user engagement (for instance, ecommerce store), the hosting solution should be robust enough to handle spikes in traffic.

Here, I would like to introduce Cloudways PHP server hosting to you which provides easy, developer and designer friendly managed hosting platform. With Cloudways, you don't need to focus on PHP hosting, but must focus on building your application. You can easily launch cloud servers on five providers including DigitalOcean, Linode, Vultr, AWS and GCE.


Cloudways ThunderStack


Being a developer, you must be familiar with the concept of stack - an arrangement of technologies that form the underlying hosting solution.

To provide a blazing fast speed and a glitch-free performance, Cloudways has built a PHP stack, known as ThunderStack. This stack consists of technologies that offer maximum uptime and page load speed to all PHP applications. Check out the following visual representation of ThunderStack and the constituent technologies:


alt_text


As you can see, ThunderStack comprises of a mix of static and dynamic caches with two web servers, Nginx and Apache. This combination ensures the ultimate experience for the users and visitors of your application.


Frameworks and CMS


The strength and popularity of PHP lies in the variety of frameworks and CMS it offers to the developers. Realizing this diversity, Cloudways offers a hassle-free installation of major PHP frameworks including Symfony, Laravel, CakePHP, Zend, and Codeigniter. Similarly, popular CMS such as WordPress, Bolt, Craft, October, Couch, and Coaster CMS - you can install these with the 1-click option. The best part is that if you have a framework or CMS that is not on the list, you can easily install it through Composer.


1-Click PHP Server & Application Installation


Setting up a stack on an unmanaged VPS could take an entire day!

When you opt for Cloudways managed cloud hosting, the entire process of setting up the server, installation of core PHP files and then the setup of the required framework is over in a matter of minutes.

Just sign up at Cloudways, choose your desired cloud provider, and select the PHP stack application.


alt_text


As you can see, your LAMP stack is ready for business in minutes.

Many PHP applications fail because essential services are either turned off or not set up properly. Cloudways offers a centralized location where you can view and set the status of all essential services such as:



* Apache
* Elasticsearch
* Memcached
* MySQL
* PHP-FPM
* Nginx
* New Relic
* Redis
* Varnish


alt_text


Similarly, you can manage SMTP add-ons without any fuss.


Staging Environment


With Cloudways, you can test your web applications for possible bugs and errors before taking it live.

Using the staging feature, developers can first deploy their web sites on test domains where they can analyze the applications performance and potential problems. This helps site administrators to fix those issues timely and view the application performance in real-time.

A default sub domain comes pre-installed with the newly launched application, making it easy for the administrators to test the applications on those testing subdomains. Overall, it's a great feature which helps developers know about the possible errors that may arise during the live deployment.

alt_text

Pre-Installed Composer & Git


PHP development requires working with external libraries and packages. Suppose you are working with Laravel and you need to install an external package. Since Composer has become the standard way of installing packages, it comes preinstalled on the Cloudways platform. Just launch the application and start using Composer in your project.

Similarly, if you are familiar with Git and maintain your project on GitHub or BitBucket, you don’t need to worry about Git installation. Git also comes pre-configured on Cloudways. You can start running commands right after application launch.


Cloudways MySQL Manager


When you work with databases in PHP, you need a database manager. On the Cloudways platform, you will get a custom-built MySQL manager, in which you can perform all the tasks of a typical DB manager.

alt_text


However, if you wish to install and use another database manager like PHPMyAdmin, you can install it by following this simple guide on installing PHPMyadmin.


Server & Application Level SSH


If you use Linux, you typically use SSH for accessing the server(s) and individual applications. A third-party developer requires application and server level access as per the requirements of the client. Cloudways offers SSH access to fit the requirements of the client and users.

alt_text


PHP-FPM, Varnish & Cron Settings


Cloudways provides custom UI panel to set and maintain PHP-FPM and Varnish settings. Although the default configuration is already in place, you can easily change all the settings to suit your own, particular development related requirements. In Varnish settings, you can define URL that you want to exclude from caching. You can also set permissions in this panel.

alt_text


Cron job is a very commonly used component of PHP application development process. On Cloudways platform, you can easily set up Cron jobs in just a few clicks. Just declare the PHP script URL and the time when the script will run.

alt_text


Cloudways API & Personal Assistant Bot


Cloudways provides an internal API that offers all important aspects of the server and application management. Through Cloudways API, you can easily develop, integrate, automate, and manage your servers and web apps on Cloudways Platform using the RESTful API. Check out some of the use cases developed using Cloudways API. You just need your API key and email for authentication of the HTTP calls on API Playground and custom applications.

alt_text


Cloudways employs a smart assistant named CloudwaysBot to notify all users about server and application level issues. CloudwaysBot sends the notifications on pre-approved channels including email, Slack and popular task management tools such as Asana and Trello.


Run Your APIs on PHP Stack


Do you have your own API which you want to run on the PHP stack? No problem, because you can do that, too with Cloudways! You can also use REST API like Slim, Silex, Lumen, and others. You can use APIs to speed up performance and require fast servers with lots of resources. So, if you think that your API response time is getting slower due to the large number of requests, you can easily scale your server(s) with a click to address the situation.


Team Collaboration


When you work on a large number of applications with multiple developers, you need to assign them on any specific application. Cloudways provides an awesome feature of team collaboration through which you can assign developers to specific application and give access to them. You can use this tool to assign one developer to multiple applications. Through team feature, you can connect the team together and work on single platform. Access can be of different type; i.e. billing, support and console. You can either give the full access or a limited one by selecting the features in Team tab.

alt_text


Final Words


Managed cloud hosting ensures that you are not bothered by any hosting or server related issues. For practical purposes, this means that developers can concentrate on writing awesome code without worrying about underlying infrastructure and hosting related issues. Do sign up and check out Cloudways for the best and the most cost-effective cloud hosting solution for your next PHP project!

PHP CHAT WITH SOCKETS

Hey Friends,

I am sharing a very interesting blog on how to create a chat system in php without using ajax. As we all know ajax based chat system in php is not a good solution
because itincreases the server load and redundant xhr calls on our server.

Instead, I am going to use sockets for incoming messages from and send messages to another user. So lets try them out using the following steps:


Step 1: Cross check in php.ini that sockets extension is enabled


;extension=sockets
extension=sockets


Step 2: Create server.php file


This file will handle the incoming and outgoing messages on sockets, Add following variables in top of the file:

$host = 'localhost';
$port = '9000';
$null = NULL; 


Step 3: After it add helper methods


The following code for handshake with new incoming connections and encrypt and decrypt messages incoming and outgoing over sockets:

function send_message($msg)
{
global $clients;
foreach($clients as $changed_socket)
{
@socket_write($changed_socket,$msg,strlen($msg));
}
return true;
}
function unmask($text) {
$length = ord($text[1]) & 127;
if($length == 126) {
$masks = substr($text, 4, 4);
$data = substr($text, 8);
}
elseif($length == 127) {
$masks = substr($text, 10, 4);
$data = substr($text, 14);
}
else {
$masks = substr($text, 2, 4);
$data = substr($text, 6);
}
$text = "";
for ($i = 0; $i < strlen($data); ++$i) {
$text .= $data[$i] ^ $masks[$i%4];
}
return $text;
}
function mask($text)
{
$b1 = 0x80 | (0x1 & 0x0f);
$length = strlen($text);

if($length <= 125)
$header = pack('CC', $b1, $length);
elseif($length > 125 && $length < 65536)
$header = pack('CCn', $b1, 126, $length);
elseif($length >= 65536)
$header = pack('CCNN', $b1, 127, $length);
return $header.$text;
}
function perform_handshaking($receved_header,$client_conn, $host, $port)
{
$headers = array();
$lines = preg_split("/

/", $receved_header);
foreach($lines as $line)
{
$line = chop($line);
if(preg_match('/\A(\S+): (.*)\z/', $line, $matches))
{
$headers[$matches[1]] = $matches[2];
}
}
$secKey = $headers['Sec-WebSocket-Key'];
$secAccept = base64_encode(pack('H*', sha1($secKey . '258EAFA5-E914-47DA-95CA-C5AB0DC85B11')));
$upgrade = "HTTP/1.1 101 Web Socket Protocol Handshake

" .
"Upgrade: websocket

" .
"Connection: Upgrade

" .
"WebSocket-Origin: $host

" .
"WebSocket-Location: ws://$host:$port/php-ws/chat-daemon.php

".
"Sec-WebSocket-Accept:$secAccept



";
socket_write($client_conn,$upgrade,strlen($upgrade));
}


Step 4: Now add following code to create bind and listen tcp/ip sockets:


$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($socket, 0, $port);
socket_listen($socket);
$clients = array($socket);


Ok now a endless loop that will use for handeling incominga nd send messages:

while (true) {
$changed = $clients;
socket_select($changed, $null, $null, 0, 10);

if (in_array($socket, $changed)) {
$socket_new = socket_accept($socket); $clients[] = $socket_new;
$header = socket_read($socket_new, 1024); perform_handshaking($header, $socket_new, $host, $port);
socket_getpeername($socket_new, $ip); $response = mask(json_encode(array('type'=>'system', 'message'=>$ip.' connected'))); send_message($response);
$found_socket = array_search($socket, $changed);
unset($changed[$found_socket]);
}

foreach ($changed as $changed_socket) {

while(socket_recv($changed_socket, $buf, 1024, 0) >= 1)
{
$received_text = unmask($buf); $tst_msg = json_decode($received_text, true); $user_name = $tst_msg['name']; $user_message = $tst_msg['message']; $user_color = $tst_msg['color'];
$response_text = mask(json_encode(array('type'=>'usermsg', 'name'=>$user_name, 'message'=>$user_message, 'color'=>$user_color)));
send_message($response_text); break 2; }

$buf = @socket_read($changed_socket, 1024, PHP_NORMAL_READ);
if ($buf === false) { $found_socket = array_search($changed_socket, $clients);
socket_getpeername($changed_socket, $ip);
unset($clients[$found_socket]);

$response = mask(json_encode(array('type'=>'system', 'message'=>$ip.' disconnected')));
send_message($response);
}
}
}
socket_close($socket);


So you are ready with server side socket program, Now its time to move on front side where we will implement w3c provided client side Web Socket Apis,

Step 5: create a file named index.php for frontend usage with following initial code


$host = 'localhost';
$port = '9000';
$subfolder = "php_ws/";
$colors = array('#007AFF','#FF7000','#FF7000','#15E25F','#CFC700','#CFC700','#CF1100','#CF00BE','#F00');
$color_pick = array_rand($colors);
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<div class="chat-wrapper">
<div id="message-box"></div>
<div class="user-panel">
<input type="text" name="name" id="name" placeholder="Your Name" maxlength="15" />
<input type="text" name="message" id="message" placeholder="Type your message here..." maxlength="100" />
<button id="send-message">Send</button>
</div>
</div>
</body>
</html>


Now add some basic styling in the head section using following code:

<style type="text/css">
.chat-wrapper {
font: bold 11px/normal 'lucida grande', tahoma, verdana, arial, sans-serif;
background: #00a6bb;
padding: 20px;
margin: 20px auto;
box-shadow: 2px 2px 2px 0px #00000017;
max-width:700px;
min-width:500px;
}
#message-box {
width: 97%;
display: inline-block;
height: 300px;
background: #fff;
box-shadow: inset 0px 0px 2px #00000017;
overflow: auto;
padding: 10px;
}
.user-panel{
margin-top: 10px;
}
input[type=text]{
border: none;
padding: 5px 5px;
box-shadow: 2px 2px 2px #0000001c;
}
input[type=text]#name{
width:20%;
}
input[type=text]#message{
width:60%;
}
button#send-message {
border: none;
padding: 5px 15px;
background: #11e0fb;
box-shadow: 2px 2px 2px #0000001c;
}
</style>


Ok Style is all set now need to add a jquery script and create web socket object and handle all events on it as following code need to add before closing of bosy tag:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
var msgBox = $('#message-box');
var wsUri = "ws://".$host.":".$port."/php-ws/server.php";
websocket = new WebSocket(wsUri);

websocket.onopen = function(ev) { msgBox.append('<div class="system_msg" style="color:#bbbbbb">Welcome to my "Chat box"!</div>'); }
websocket.onmessage = function(ev) {
var response = JSON.parse(ev.data);
var res_type = response.type; var user_message = response.message; var user_name = response.name; var user_color = response.color; switch(res_type){
case 'usermsg':
msgBox.append('<div><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="user_message">' + user_message + '</span></div>');
break;
case 'system':
msgBox.append('<div style="color:#bbbbbb">' + user_message + '</div>');
break;
}
msgBox[0].scrollTop = msgBox[0].scrollHeight; };

websocket.onerror = function(ev){ msgBox.append('<div class="system_error">Error Occurred - ' + ev.data + '</div>'); };
websocket.onclose = function(ev){ msgBox.append('<div class="system_msg">Connection Closed</div>'); };
$('#send-message').click(function(){
send_message();
});

$( "#message" ).on( "keydown", function( event ) {
if(event.which==13){
send_message();
}
});

function send_message(){
var message_input = $('#message'); var name_input = $('#name');
if(message_input.val() == ""){ alert("Enter your Name please!");
return;
}
if(message_input.val() == ""){ alert("Enter Some message Please!");
return;
}
var msg = {
message: message_input.val(),
name: name_input.val(),
color : '<?php echo $colors[$color_pick]; ?>'
};
websocket.send(JSON.stringify(msg));
message_input.val(''); }
</script>


Ok All set, Now need to run the server.php file using following php-cli utility,make sure you have php cli utility installed in your system:

php -q c:\xampp\htdocs\php-ws\server.php


Now you may access the front index.php file via the browser url like following and see a chatbox and connection status, you may use the same url or different browser to check the chat system is working or not.

Midwest PHP and Nomad PHP Join Forces!

A little history

Several years ago I had the distinct privilege of founding Midwest PHP with Jonathan Sundquist. The goal was simple, to bring an affordable PHP conference to Minnesota and the midwest region.

Midwest PHP was created for one simple reason - there weren't a lot of alternatives, especially affordable ones. At the time, your choices were ZendCon in Silicon Valley, php[tek] in Chicago, or Northeast PHP in Boston. While Northeast PHP formed the blueprint of a community conference - it still required a flight and a costly hotel in Boston. I wanted something where local attendees, college students, and those just beginning in their PHP careers could go to learn, network, and become part of the PHP community.

Shortly after Midwest PHP was formed (originally we were using the name PHPFreeze - until Sundquist told me what a horrible idea it was), Adam Culp launched Sunshine PHP which has become one of the top community focused PHP conferences (but still requires that flight and hotel in Miami). Sundquist and I knew that any reasonable developer would still prefer to attend a conference in a blizzard than enjoy the beautiful Floridian weather (ok, that might not be it, but we still understood the need that existed).

After moving to California for my new job, Jonathan Sundquist continued to run Midwest PHP as more community conferences appeared. With his efforts, and the torch being passed to Mike Willbanks, Midwest PHP celebrated it's seventh consecutive year, becoming the longest continuously running PHP conference (if you go by formed date, if you go by actual conference date Sunshine PHP beats us out by a month).


A renewed focus


Developers at Midwest PHP

Because of the incredible work Jonathan and Mike have done, Midwest PHP has stood the test of time - and the peaks and valleys that come with any conference. With the shifts in the PHP community and the sad loss of several community conferences - we realized the need for Midwest PHP is more now than ever, and to meet that need we needed to reimagine the way the conference operated.

We also realized that the best way to make Midwest PHP accessible was to combine forces, creating a seamless partnership between Nomad PHP and Midwest PHP. Through this partnership we're not only able to stream the event to make it more accessible ($19.95/mo), but also expand the conference.

This year, taking place onApril 2-4, 2020 - Midwest PHP will bring together over 800 developers both in-person and virtually! Making this year truly unique, however, and staying with our purpose of helping new developers be part of the PHP community is abrand new, FREE, beginner track. I'm excited to say we will be giving away 200 tickets to those wishing to attend our Beginner or Learn PHP track!!!

We will also work to keep prices as low as possible as we offer our standard PHP tracks (Everyday PHP and PHP Performance & Security) starting at $250/ person, anda brand new enterprise track geared at developers facing challenges at unprecedented scale starting at $450/ person.

Last but not least, it is our goal with the help of our sponsors to include the workshop day as part of your ticket price - allowing you to get one day of in-depth training, and two more full days of sessions. On top of this, we're also excited to make the Nomad PHP and Nomad JS video libraries available for Standard and Enterprise attendees, providing over 220 additional virtual sessions on demand!


For sponsors

Sponsoring a conference is hard. We understand the challenge of gauging ROI, planning travel, and coordinating outreach. With the combined forces of Midwest PHP and Nomad PHP, we're able to offer sponsors unique plans that maximize their investment - while ensuring the funds go back into the event to create an amazing experience for our attendees.

Beyond Midwest PHP's goal to be the largest PHP conference this year - the included Nomad PHP advertising will help you reach a much larger and broader audience, allowing for follow up advertisements and consistent engagement with the PHP community.

Introduction to Gitlab CI for PHP developers
As a developer, you've probably at least heard something about CI - Continuous integration. And if you haven't - you better fix it ASAP, because that's something awesome to have on your skill list and can get extremely helpful in your everyday work. This post will focus on CI for PHP devs, and specifically, on CI implementation from Gitlab. I will suppose you know the basics of Git, PHP, PHPUnit, Docker and unix shell. Intended audience - intermediate PHP devs.
Adding something to your workflow must serve a purpose. In this case the goal is to automate routine tasks and achieve better quality control. Even a basic PHP project IMO needs the following:
* linter) checks (cannot merge changes that are invalid on the syntax level)
* Code style checks
* Unit and integration tests
All of those can be just run eventually, of course. But I prefer an automated CI approach even in my personal projects because it leads to a higher level of discipline, you simply can't avoid following a set of rules that you've developed. Also, it reduces a risk of releasing a bug or regression, thus improving quality.
Gitlab is as generous as giving you their CI for free, even for your private repos. At this point it is starting to look as advertising, therefore a quick comparison table for Gitlab, Github, Bitbucket. AFAIK, Github does not have a built-in solution, instead it is easily integrated with third parties, of which Travis CI seems to be the most popular - I will therefore mention Travis here.

Public repositories (OSS projects). All 3 providers have a free offer for the open-source community!


| Provider | Limits |
|---|---|
| Gitlab | 2,000 CI pipeline minutes per group per month, shared runners |
| Travis | Apparently unlimited |
| Bitbucket| 50 min/month, max 5 users, File storage <= 1Gb/month |

Private repositories


| Provider | Price | Limits |
|---|---|---|
| Gitlab | Free | 2,000 CI pipeline minutes per group per month, shared runners |
| Travis | $69/month | Unlimited builds, 1 job at a time |
| Bitbucket| Free | 50 min/month, max 5 users, File storage <= 1Gb/month |

Getting started

I made a small project based on Laravel framework and called it "ci-showcase". I work in Linux environment, and the commands I use in the examples, are for linux shell. They should be pretty much the same on Mac and nearly the same on Windows though.
composer create-project laravel/laravel ci-showcase

Next, I went to gitlab website and created a new public project: https://gitlab.com/crocodile2u/ci-showcase. Cloned the repo and copied all files and folders from the newly created project - the the new git repo. In the root folder, I placed a .gitignore file:
.idea
vendor
.env

Then the .env file:
APP_ENV=development

Then I generated the application encryption key: php artisan key:generate, and then I wanted to verify that the primary setup works as expected: ./vendor/bin/phpunit, which produced the output OK (2 tests, 2 assertions). Nice, time to commit this: git commit &amp;&amp; git push

At this point, we don't yet have any CI, let's do something about it!

Adding .gitlab-ci.yml

Everyone going to implement CI with Gitlab, is strongly encouraged to bookmark this page: https://docs.gitlab.com/ee/ci/README.html. I will simply provide a short introduction course here plus a bit of boilerplate code to get you started easier.
First QA check that we're going to add is PHP syntax check. PHP has a built-in linter, which you can invoke like this: php -l my-file.php. This is what we're going to use. Because the php -l command doesn't support multiple files as arguments, I've written a small wrapper shell script and saved it to ci/linter.sh:
#!/bin/sh
files=<code>sh ci/get-changed-php-files.sh | xargs</code>last_status=0
status=0
# Loop through changed PHP files and run php -l on each
for f in "$files" ; do message=<code>php -l $f</code> last_status="$?" if [ "$last_status" -ne "0" ]; then # Anything fails -> the whole thing fails echo "PHP Linter is not happy about $f: $message" status="$last_status" fi
done
if [ "$status" -ne "0" ]; then echo "PHP syntax validation failed!"
fi
exit $status

Most of the time, you don't actually want to check each and every PHP file that you have. Instead, it's better to check only those files that have been changed. The Gitlab pipeline runs on every push to the repository, and there is a way to know which PHP files have been changed. Here's a simple script, meet ci/get-changed-php-files.sh:
#!/bin/sh
# What's happening here?
#
# 1. We get names and statuses of files that differ in current branch from their state in origin/master.
# These come in form (multiline)
# 2. The output from git diff is filtered by unix grep utility, we only need files with names ending in .php
# 3. One more filter: filter *out* (grep -v) all lines starting with R or D.
# D means "deleted", R means "renamed"
# 4. The filtered status-name list is passed on to awk command, which is instructed to take only the 2nd part
# of every line, thus just the filename
git diff --name-status origin/master | grep '\.php$' | grep -v "^[RD]" | awk '{ print }'

These scripts can easily be tested in your local environment ( at least if you have a Linux machine, that is ;-) ).
Now, as we have our first check, we'll finally create our .gitlab-ci.yml. This is where your pipeline is declared using YAML notation:
# we're using this beautiful tool for our pipeline: https://github.com/jakzal/phpqa
image: jakzal/phpqa:alpine
# For this sample pipeline, we'll only have 1 stage, in real-world you would like to also add at least "deploy"
stages: - QA
linter:
stage: QA
# this is the main part: what is actually executed
script: - sh ci/get-changed-php-files.sh | xargs sh ci/linter.sh

The first line is image: jakzal/phpqa:alpine and it's telling Gitlab that we want to run our pipeline using a PHP-QA utility by jakzal. It is a docker image containing PHP and a huge variety of QA-tools. We declare one stage - QA, and this stage by now has just a single job named linter. Every job can have it's own docker image, but we don't need that for the purpose of this tutorial. Our project reaches Step 2. Once I had pushed these changes, I immediately went to the project's CI/CD page. Aaaand.... the pipeline was already running! I clicked on the linter job and saw the following happy green output:
Running with gitlab-runner 11.9.0-rc2 (227934c0) on docker-auto-scale ed2dce3a

Skipping Git submodules setup
$ sh ci/get-changed-php-files.sh | xargs sh ci/linter.sh
Job succeeded

It means that our pipeline was successfully created and run!

PHP Code Sniffer.

PHP Code Sniffer is a tool for keeping app of your PHP files in one uniform code style. It has a hell of customizations and settings, but here we will only perform simple check for compatibilty with PSR-2 standard. A good practice is to create a configuration XML file in your project. I will put it in the root folder. Code sniffer can use a few file names, of which I prefer phpcs.xml:
<?xml version="1.0"?>
/resources

I also will append another section to .gitlab-ci.yml:
code-style:	stage: QA	script:	# Variable $files will contain the list of PHP files that have changes	- files=<code>sh ci/get-changed-php-files.sh</code> # If this list is not empty, we execute the phpcs command on all of them - if [ ! -z "$files" ]; then echo $files | xargs phpcs; fi

Again, we check only those PHP files that differ from master branch, and pass their names to phpcs utility. That's it, Step 3 is finished! If you go to see the pipeline now, you will notice that linter and code-style jobs run in parallel.

Adding PHPUnit

Unit and integration tests are essential for a successful and maintaiable modern software project. In PHP world, PHPUnit is de facto standard for these purposes. The PHPQA docker image already has PHPUnit, but that's not enough. Our project is based on Laravel, which means it depends on a bunch of third-party libraries, Laravel itself being one of them. Those are installed into vendor folder with composer. You might have noticed that our .gitignore file has vendor folder as one of it entries, which means that it is not managed by the Version Control System. Some prefer their dependencies to be part of their Git repository, I prefer to have only the composer.json declarations in Git. Makes the repo much much smaller than the other way round, also makes it easy to avoid bloating your production builds with libraries only needed for development.
Composer is also included into PHPQA docker image, and we can enrich our .gitlab-ci.yml:
test:	stage: QA	cache:	key: dependencies-including-dev	paths: - vendor/	script:	- composer install	- ./vendor/bin/phpunit

PHPUnit requires some configuration, but in the very beginning we used composer create-project to create our project boilerplate.laravel/laravel package has a lot of things included in it, and phpunit.xml is also one of them. All I had to do was to add another line to it:
xml

APP_KEY enironment variable is essential for Laravel to run, so I generated a key with php artisan key:generate.
git commit & git push, and we have all three jobs on theQA stage!

Checking that our checks work

In this branch I intentionally added changes that should fail all three job in our pipeline, take a look at git diff. And we have this out from the pipeline stages:Linter:
$ ci/linter.sh
PHP Linter is not happy about app/User.php:
Parse error: syntax error, unexpected 'syntax' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST) in app/User.php on line 11
Errors parsing app/User.php
PHP syntax validation failed!
ERROR: Job failed: exit code 255

**Code-style**:
$ if [ ! -z "$files" ]; then echo $files | xargs phpcs; fi

Congratulations, our pipeline is running, and we now have much less chance of messing up the result of our work.

Conclusion

Now you know how to set up a basic QA pipeline for your PHP project. There's still a lot to learn. Pipeline is a powerful tool. For instance, it can make deployments to different environments for you. Or it can build docker images, store artifacts and more! Sounds cool? Then spend 5 minutes of your time and leave a comment, you can also tell me if there is a pipeline topic you would like to be covered in next posts.

Press Release

To say that we have been hard at work here at Nomad PHP, or that I'm excited about these three announcements would be a tremendous understatement. Over the past several months, behind the scenes, we've been working to bring even more features and benefits to Nomad PHP - these have already included unlimited streaming of all past meetings and access to PHP Architect.

Available today, however, you'll also have access to online, live workshops - as well as soon have the ability to stream select PHP conferences live, and finally to prove the knowledge you have gained through our online certification.

Online, Live Workshops

Like our online meetings, we are excited to announce that available today you can participate in online, live, and interactive workshops. Our first workshop will feature Michael Stowe, author of Undisturbed REST: a guide to Designing the Perfect API as he demonstrates how to build the perfect API using modern technologies and techniques.

Additional workshops will be announced as we continue, with a minimum of one workshop per quarter. These workshops will be part of your Nomad PHP subscription, and will be recorded for later viewing.

Nomad PHP Certification

With the many changes impacting the PHP ecosystem, we're proud to announce the ability to prove your knowledge with our online certification. Each certification is made up numerous, randomly selected questions to be completed within a specific time frame. Depending on the exam it may or may not be proctored, but all exams monitor user activity to ensure compliance.

To pass the exam, a passing grade (specified on each exam) must be completed for each section within the allotted time frame. Failure to complete or pass any section will result in a failing grade for the entire exam.

Upon completion, you will receive a digital certification with verification to post on LinkedIn or your website, as well as having your Nomad PHP updated to show the passed certification.

Initial certification exams will include PHP Developer Level I, PHP Engineer Level II, and API Specialist Level I. The PHP Developer exam will cover core components of PHP, the Engineer will cover a broad spectrum of topics including modern technologies, and the API Specialist will cover REST design and architecture practices.

All three exams will be available by January 31, 2019, and will be included with a Nomad PHP subscription.

Stream Select PHP Conferences Live

One of the primary goals of Nomad PHP is to bring the community together, and allow users all over the country to participate in conference level talks. What better way to do this than to bring community conferences online?

Like our traditional talks, these conferences and select conference sessions will be live-streamed as part of your Nomad PHP subscription, allowing you to participate in real-time with in-person conference attendees.

The first conference to be streamed will be DayCamp4Developers: Beyond Performance on January 18, 2018. Additional conferences to be streamed will be announced shortly.

Community and Corporate Sponsorships

With these new additions to Nomad PHP, now is the perfect time to take advantage of our new Community and Corporate sponsorships.
