note 40610 deleted from function.is-callable by derick

Note Submitter: ckrack at i-z dot de ---- 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.
