Or you can use various caching algorithms (LRU, MRU, ..) to reduce memory usage:

$this->cache = new ArrayLimit(2);
$this->cache->add(new LargeObject('A'));
$this->cache->add(new LargeObject('B'));
$this->cache->add(new LargeObject('C'));
$this->cache->count(); // 2

To solve a "caching problem" weak references aren't very helpful since there's
no way to know when or which objects will be garbage collected (non-deterministic).
