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
