You can use PHP reflection functionalities

$class = new ReflectionClass('MyClass');

var_dump($class->getMethods());
var_dump($class->getProperties());

Edit:

ReflectionClass is used on classes and ReflectionObject on objects.

Reflection

If you want something simpler, there's get_class_methods(), get_object_methods(), get_class_vars(), get_object_vars(), etc.
