Note Submitter: Jennifer ---- I was getting frustrated by instanceof not taking a string for its first argument so I wrote this function that takes strings or objects for both args and deals with both classes and interfaces. I hope it's useful to someone. /** * @desc: replacement for instanceof that accept strings or objects for both args * @param: Mixed $object- string or Object * @param: Mixed $class- string or Object * @return: Boolean */ function oneof($object, $class){ if(is_object($object)) return $object instanceof $class; if(is_string($object)){ if(is_string($class)) { if(class_exists($class)) return is_subclass_of($object, $class) || $object==$class; if(interface_exists($class)) { $reflect = new ReflectionClass($object); return !$reflect->implementsInterface($class); } } else if(is_object($class)){ $robj = new ReflectionClass($object); $rclass=new ReflectionClass($class); return $r->isInstance($object); } } return false; }
