How to tell whether I'm static or an object?

Question

Does anybody know offhand the way to tell whether I'm being called statically (Classname::function) or inside an object ($classInstance->function) inside a PHP method?

Answer 1

Admittedly not offhand...but Sean Coates has a cool and fairly simple approach to finding this out:

$isStatic = !(isset($this) && get_class($this) == __CLASS__);

Answer 2

Check if $this is set and equal to the class. It will be equal for an instance call and non-equal (or null) for a static call.
