What we really need is a get_hash_t handler on the object, so that each object knows how to hash itself. This can also come in handy when using objects as array keys. -Andrei On Aug 10, 2005, at 3:39 PM, Marcus Boerger wrote:

Hello Andrey, wrong assumption. That is only the handle but only the handle+handler combination is unique. marcus Thursday, August 11, 2005, 12:32:07 AM, you wrote:

Hello Andrey, thanks! I wanted to do it earlier but had no idea how to sole the problem. I actually right from the beginning wanted to do all three in there. Anyway you might also want to see t he last slides of my last presentation (the one from OSCON) which you can find here: http://talks.somabo.de/ best regards marcus Thursday, August 11, 2005, 12:04:37 AM, you wrote:

Wonderful idea Helly!

However, I think you are wrong that it cannot be implemented in user land with O(1) complexity. The following one-liner should give you a hint why I think it is possible.

andrey@lmy004:~/test> php -r 'class a{} function get_hash_key($obj){ ob_start(); var_dump($obj); $v=ob_get_contents(); ob_end_clean();var_dump(substr($v, 7, strpos($v, " ", 11) - 7));} get_hash_key(new a);' string(4) "a)#1"

The string is unique per object. ) and # are noise but they are not a problem.

Best wishes, Andrey
