$cache = app("cache");
app("cache"")
and expect a Cache\Repository
instance as result. If I pass the result of this call to a function that requires a Cache\Repository
as parameter, I will probably have a code inspection warning from IDE. Moreover, if I want proper autocompletion, I will have to add additional comment:
$cache = app("cache");
namespace App;
class MyApp extends Application
{
public function cacheRepository(): Repository
{
return $this->make(Repository::class);
}
}
TypeError
in case of a misconfiguration, and I have a type-hint which allows the IDE to recognize the return value. Bye-bye nasty comment lines and IDE warnings! I make a method per service, with type-hints, like dbConnection()
or viewFactory()
- works really well for me!bootstrap/app.php
, should reside in that custom class:namespace App;
class MyApp extends Application
{
public function __construct()
{
define('LARAVEL_START', microtime(true));
define("APP_ROOT", realpath(__DIR__ . "/../"));
parent::__construct(APP_ROOT);
$this->setUp();
}
private function setUp()
{
$this->singleton(
Contracts\Http\Kernel::class,
\App\Http\Kernel::class
);
}
}
bootstrap/app.php
becomes just this:return new \App\MyApp;
app()
function will also return an instance of MyApp from now on. However, it's @phpdoc says it returns \Illuminate\Foundation\Application
, so for better clarity, I also added my own accessor method:namespace App;
class MyApp extends Application
{
public static function app(): self
{
$ret = parent::getInstance();
return $ret;
}
}
MyApp::app()
. The IDE wil be aware of the return type due to the type-hint, so I get everything I want for clean and clear development..php

tag, then we write our PHP code, and finally close it with the ?>
tag. This is important as if we were creating an XML file and forgot to escape the opening XML tag which also has a question mark, we would run into a fatal error.echo
statement in our PHP code by placing the text we want to echo in single quotes and then end the command with a semi colon. Let's echo out "there!":

Hello <?php echo 'there!'; ?>

in the querystring, we can use $_GET['name']
like so:

<title>Hello</title>

Hello <?php echo $_GET['name']; ?>

along with the PHP date()
function. You can learn more about how to use different date formats to output the date here, but we'll be using the date()
function to get back the hour of the day (based on the server's time) between 0 (midnight) and 23 (11pm). We'll then use greater than (>) to determine what to assign to our $time
variable which we'll output with the user's name.
