for creating the short URL:function GetShortUrl($url){

generateUniqueID()
function to generate a unique id for long urls. We can generate and retrieve the unique ID like so:function generateUniqueID(){

header("location:".$url);
exit;
}
GetRedirectUrl()
that we need to define, like so:function GetRedirectUrl($slug){
global $conn;
$query = "SELECT * FROM url_shorten WHERE short_code = '".addslashes($slug)."' ";
$result = $conn->query($query);
if ($result->num_rows > 0) {

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.composer create-project laravel/laravel --prefer-dist tiny_blog
cd tiny_blog
