Bug description:Register callbacks to an object's lifespan.
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
});
