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
