 1 | # Ping for Laravel
 2 | 
 3 | This Laravel package is simple and unopinionated. It simply returns the HTTP Status Code for a provided URL.
 4 | 
 5 | ## Installation
 6 | 
 7 | Install via Composer:
 8 | ```bash
 9 | composer require karlmonson/laravel-ping
10 | ```
11 | You'll need to register the ServiceProvider and Facade:
12 | ```php
13 | // config/app.php
14 | 
15 | 'providers' => [
16 |     // ...
17 |     Karlmonson\Ping\PingServiceProvider::class,
18 | ];
19 | 
20 | 'aliases' => [
21 |     // ...
22 |     'Ping' => Karlmonson\Ping\Facades\Ping::class,
23 | ];
24 | ```
25 | 
26 | ## Usage
27 | 
28 | ```php
29 | <?php
30 | 
31 | namespace App\Http\Controllers;
32 | 
33 | use Ping;
34 | use App\Http\Controllers\Controller;
35 | 
36 | class LinkController extends Controller
37 | {
38 |     /**
39 |      * Show the current health of a given URL.
40 |      *
41 |      * @param  string  $url
42 |      * @return string
43 |      */
44 |     public function healthCheck($url)
45 |     {
46 |         $health = Ping::check($url);
47 | 
48 |         if($health == 200) {
49 |             return 'Alive!';
50 |         } else {
51 |             return 'Dead :(';
52 |         }
53 |     }
