Note Submitter: jake at example dot com ---- Ignore the comment by Anonymous on 08-Apr-2009 03:43, it is completely fictionalized. Garbage collection with cycles is all about detecting cyclic references for collection which would otherwise be missed by reference counting. If you had something like: <?php class Child { public $parent; } class Parent { public $child; } ?> If a Child instance and Parent instance point to each other, they would never be collected without cycle detection even if no other references to them existed. These gc_* functions are to allow detection and collection of structures like this.
