Merhaba ben bu gibi görünen bir oturumu e hav:

      ["zaal_id"]=>
      string(1) "1"
      ["zaaltitel"]=>
      string(6) "zaal 1"
      ["tijdstip"]=>
      string(8) "15:00:00"

    }
  }
}

Şimdi, gelen $_SESSION['addedToCart] i onlar gibi bazı koşullara uyarsa dizileri kaldırmak istiyoruz. Ben aşağıdaki denedim.

foreach ($_SESSION["addedToCart"] as $arr) {
       if ($arr["stoeltjes"] == $stoeltje && $arr['film_id'] == $id) {
            unset($arr);
       }
 }

this doesnt seem to work, it doesnt remove anything, i did a var_dump to check if the variables $stoeltje and $id were fine and they were fine so that cant be the problem. am i able to use unset in this kind of situation?
