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()';

}

?>
