bool class_exists ( string $class_name [, bool $autoload ] ) — Check whether the class has been defined
string get_called_class ( void ) — Get the class name of the static method call

class foo {
static public function test(){
var_dump(get_called_class());
}
}
class bar extends foo {}
foo::test();
bar::test();
