I use version laravel 5.4

In Helpers/Helper.php

public function test()
{
  return 'success';
}

In controller

use App\Helpers\Helper;

public function index()
{
  $val = Helper::test();
  dd($val);
}

Error : Helper::test() should not be called statically

I called the function inside helper to use it. But got the error as above. Please show me how to get the function in helper. Thank you

CodePudding user response：

To call the test function statically you must define it as a static function, like below. Otherwise, you would have to do something like (new Helper())->test(); which is probably not something you want to do for a simple helper function that doesn't need to access $this. You can read a bit more about the use of static methods in the PHP manual https://www.php.net/manual/en/language.oop5.static.php

namespace App\Helpers;

class Helper
{
    public static function test()
    {
        return 'success';
    }
}
