<?php class a { static public function o() { return true;} } $cls = [ 'a::o' ]; foreach($cls as $cl) { echo var_export($cl, true); echo "\t"; echo "is_callable\n"; var_dump(is_callable($cl)); echo "is_callable by syntax\n"; var_dump(is_callable($cl,true)); echo "instance of closure\n"; var_dump($cl instanceof Closure); }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
