I didn't mean to be rude but how a language structure could be dangerous ? You use it if you know how to otherwise you don't. I don't understand why we should not implement something because it could be bad used by some persons as far it useful for others. >> I don't mean unset($this) is the best wy to allow an object to destroy >> itself.

In my opinion if you have a need > for a class to destroy itself then you have a fundamental design flaw. I want the object to be destroyed when a specific method of this object is called because when it has been called, the object has no reason to exist anymore. It's like a SQL resource, when you have freed it, you don't need it anymore. >>>> As it can't be done I tried to unset an object by unsetting a reference >>>> of this object but it has no effect on the object but only on the >>>> reference. >>>> >>>> Should unset destroy the reference itself and the object ??? >>> No, it's not meant to (and I doubt it will change).

Or am I not understanding your diction? I would like to implement it in order to delete automaticly from memory useless objects. It can be really useful for example to make schedulers in PHP in order to avoid "max memory usage exceeded" errors. > -Stut > > -- > http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
