Hi, It may have already been proposed, but I give it a shot: I believe it would be nice to be able to dynamically reference static members and constants. Currently, there is no way to do that and the only way would be to create a static method and use call_user_func(array($classname, 'getThat')); In other words: class A { public static $foo = 'bar'; const gee = 'zzz'; public static function getFoo() { return self::$foo; } } $classname = 'A'; echo $classname::$foo; // bar echo $classname::gee; // zzz // instead of: echo call_user_func(array($classname, 'getFoo')); Please take a look at the patch I made for it. For consistency purposes, I also implemented $classname::myMethod(); even if it's not required. FWIW, I've no strong feeling about it. Regards,

Hello Etienne, besides a tiny bit of whitespace issues the patch looks fine. Actually we use tabs at the beginning of lines here (prior and after |'s). Once you got more people looking/commenting on the patch we mde decide whetehr to apply it. best regards marcus Tuesday, March 6, 2007, 4:06:55 PM, you wrote:
