Note if an invalid number of arguments are passed to a built-in function an ArgumentCountError exception will be thrown if and only if your code is in strict mode.

<?php
declare(strict_types = 1);

try {
    echo strlen('ahmed', 4);
} catch (ArgumentCountError $e) {
    echo $e->getMessage()';
}
?>
