[SOLVED] Checking if a class implements/extends another

[jordanwb]

How would I go about checking if a class extends or implements and class or interface?

[DarkWater]

The instanceof operator works on parents and interfaces too.

<?php
class foo{
}
class bar extends foo {
}
$bar = new bar;
if ($bar instanceof foo) {
echo "FOO!";
}
else {
echo "BAR!";
}
?>

 

Echos "FOO!".

Thanks.
