перезапись URL — редактирование с помощью вызова функции переполнения стека

Я упаковываю функции в страницы php в functions.php и для доступа к этим страницам я помещаю действие и значение в URL. У меня также есть функция function_calls.php, которая запрашивает действие и его значение и передает его в регистр переключателя, который вызывает соответствующую функцию. У меня проблема в том, что я хочу изменить поле. У меня нет подходящего случая (для коммутатора), который я хочу выглядеть примерно так admin.php?action=edit?id=some_id,

function_calls.php

 <?php
require_once "functions.php";


if (isset($_REQUEST['action'])) {
$option = $_REQUEST['action'];

echo $option;

switch ($option) {
case "complaints":
complaint();
break;
case "users":
users();
break;
case "officers":
officers();
break;
case "register_officer":
register_officer();
break;
case "register_student":
register_student();
break;
case "add_event":
add_event();
break;

default:
complaint();
break;
}
} else {
echo '<div class="jumbotron">
<h1>Welcome To The Administration Panel </h1>
<p>You can manage accounts and view the complaints here.</p>

</div>';
}
