ID: 65719 Updated by: ni...@php.net Reported by: metamarkers at gmail dot com Summary: Register callbacks to an object's lifespan. -Status: Open +Status: Wont fix Type: Feature/Change Request Package: Class/Object related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I think you're looking for a WeakMap here: http://de2.php.net/manual/en/class.weakmap.php Previous Comments: ------------------------------------------------------------------------ [2013-09-20 04:04:51] metamarkers at gmail dot com Description: ------------ There already exists __destruct(), but if you need to clean up mappings that use an object's identifier to cache results etc, there isn't a smooth way of doing this. It would be nice to tie a callback to an object's lifespan. The catch would of course be that you can't reference the object in the callback because of circular references, or maybe you can, I'm not that intimate with PHP's garbage collection. Test script: --------------- $x = (object)[]; register_destructor($x,function($x){ // extra cleanup operations with $x, // or instead an spl_object_hash() could be precalculated and closed over // if using $x would cause circular death }); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65719&edit=1
