Thank you in advance.

Answer

Using static method in your helper class has nothing to do with securing your application.

The question is why do we even use helper class/methods and what are helper class/methods:

Laravel has many helper methods which helps you to minimize writing to much code for common tasks:

This helper class file is located here:

vendor\laravel\framework\src\Illuminate\Foundation\helpers.php

These are some of the helper methods that comes with Laravel out-of-box:

abort - Throw an HttpException with the given data.

if (!function_exists('abort')) {
    /**
     * Throw an HttpException with the given data.
     *
     * @param  int     $code
     * @param  string  $message
     * @param  array   $headers
     * @return void

     *
     * @throws \Symfony\Component\HttpKernel\Exception\HttpException
     * @throws \Symfony\Component\HttpKernel\Exception\NotFoundHttpException
     */
    function abort($code, $message = '', array $headers = [])
    {
        return app()->abort($code, $message, $headers);
    }
}

asset - Generate an asset path for the application.

if (!function_exists('asset')) {
    /**
     * Generate an asset path for the application.
     *
     * @param  string  $path
     * @param  bool    $secure
     * @return string

     */
    function asset($path, $secure = null)
    {
        return app('url')->asset($path, $secure);
    }
}

and lots more...

So you wish to have your own Helper method, maybe because its not currently available in Laravel Helpers.

To avoid overriding Laravel helper methods, Its better you put your own helper methods in a class file:

Example: My helper class for Dates which I can reuse in my applications, might look like this:

namespace App\Helpers;

class DateHelper {


    public static function dateFormat1($date) {
        if ($date) {
            $dt = new DateTime($date);

        return $dt->format("m/d/y"); // 10/27/2014
      }
   }
}

then you could use it like so:

{{dateHelper::dateFormat1($user->created_at)}}

If we don't wish to use a class, we could have done this:

//helper method for date
function dateFormat1($date) {
            if ($date) {
                $dt = new DateTime($date);


            return $dt->format("m/d/y"); // 10/27/2014
          }
       }

and use it like this:

{{ dateFormat1($user->created_at) }}

However, what if later releases of Laravel decides to have a hepler with same name dateFormat1 then there will be a collision or overrides.

Hence its better to put you helper methods in classes.
