Limiting routing parameters for numbers only in Laravel
We may use Regular Expression [0-9]+ to accept and parse out routing URL for numbers only.
Example
<?php
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/
// will return 'Hello project root' on browser request /laravel/public
Route::get('/', function()
{
return "Hello project root";
});
Route::get('person/{id}', function($id)
{
return "Person : " . $id;
})
->where('id', '[0-9]+'); // using regular expression
Output
URL : /laravel/public/person/22
Output : Person : 22
