i was wondering whether is_callable or function exists is faster when checking class methods.
is_callable(array('foo', 'bar'));
function_exists('foo::bar');
my results when doing each operation 10000 times with a simple test class were the following:
is_callable: 0.28671383857727 seconds
function_exists: 0.14569997787476 seconds
(following tests have proved this to be true).
thus you can see, function_exists is twice as fast as is_callable.
