The guy has a class that is sitting there doing it's thing. He has a function (say it's 'DestroyMe') that should do simply that. The best case I can imagine... The class is 'object' and it interfaces with a row in a table in a database. If you're going to delete the object's row from the table, it probably makes sense to destroy the class handling it. function destroy() { delete row; destruct class; } Thus it would be helpful to be able to do what he's asking. Now whether it fits within the realm of responsible coding or not I'm not the judge... lol ------------------------------------------------------------------------ [2007-04-07 01:10:43] edwardzyang at thewritingpot dot com It's tough to understand what your problem is without more code. If you are doing: for ($i = 0; $i < 1000000; $i++) { $obj = new Foo(); // do stuff with $obj unset($obj); } That should be sufficient. Could you be more specific? Usually, if the PHP interpreter is running out of memory, you've got some bad code that needs refactoring. ------------------------------------------------------------------------ [2007-04-06 20:41:05] joel at propbot dot com The problem comes into mind when your creating an object and going through a loop. The script just grows and grows until your out of memory. We are creating an object doing what we need to do with it and trying to destroy it. Anybody have a solution? I really don't want to have to go through every variable inside the object and do an unset(). ------------------------------------------------------------------------ [2006-07-06 15:52:14] leszek@php.net It's absurd (well, maybe not absurd, but not needed) as long as PHP has destructor methods. ------------------------------------------------------------------------ [2006-07-06 15:41:19] keko_metal at hotmail dot com Scott, do you really think that $object->im_done_please_kill_me() is an absurd idea? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
