Hello, Is it possible to add Weak References to this todo list? https://bugs.php.net/bug.php?id=52318
I've been waiting over a year now for this feature. It's a critical part of object relational layer mapping and my framework will be broken until it exists. One of our important customer projects also broke down because my current work around (simply using an array) leaks huge amounts of memory due to automatic instance caching similar to the one in the example I typed down below. I'm also considering switching language since PHP lacks this important OOP concept. There does not yet seem to be an RFC for it so I typed down an example that attempts to look like real-word usage here: http://pastebin.com/pCHVK0L8 I esteimate that it's pretty simple to implement the theoretical "SplWeakArray" in the example I wrote if you have a bit of knowledge about the internals of PHP referencing and garbage collection. See the Java "WeakReference" for conceptual reference. http://download.oracle.com/javase/1.4.2/docs/api/java/lang/ref/WeakReference.html A copy of WeakReference would be a partial solution for me since I rather need a dictionary of id's mapped to objects. I don't want to go trough an array all the time and look for indexes that has been set to NULL. That's the GCs job. Hence the SplWeakArray class. ~Hannes
