Hi! I'd like to ask if there is any way of checking if a class implements given interface? Manual seems to be out of date on the subject.

instanceof PHP 5 introduces the instanceof keyword, that allows you to ascertain whether or not an object is an instance of a class, or extends a class, or implements an interface. <?php class baseClass { } $a = new baseClass; if ($a instanceof baseClass) { echo "Hello World"; } ?>
