PHP error with variable in callback function

Question

I have this function in php (laravel):

    public static function isUserParticipatesInTournament($tourId, $userId)
    {
        var_dump($userId); //dumped
             


        

Answer 1

Your $tourId variable is not in the scope of your anonymous function. Have a look at the use keyword to see how you can add it to the scope. See example 3 on this page: http://www.php.net//manual/en/functions.anonymous.php

It should look something like the following:

$obj = $user->whereHas('tournaments', function($query) use($tourId)
    {
        var_dump($tourId); // Dumps OK
    })->get();
