Trim all Request input data in Laravel

# Step (1) - Create a middleware; which use to handle the Request data.

<?php

namespace App\Http\Middleware;

use Closure;

class TrimRequestInputData
{

    /**
     * Handle incoming request.
     * Here we trim all request input value.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $trim_if_string = function ($var) {
            return is_string($var) ? trim($var) : $var;
        };

        $request->merge(array_map($trim_if_string, $request->all()));
        return $next($request);
    }

}

# Step (2) - Register this middleware in the application's global HTTP middleware 
# Location - app/Http/Kernel.php
	
  protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \App\Http\Middleware\TrimRequestInputData::class, // Here I add this Middleware.
  ];
