Why didn't it work?

Did you use PHP 5.3 with the garbage collection turned on or an ealier version? Note that any
objects with cyclic references * will never be released fro memory by PHP 5.2 and earlier.

// case 1
parent->child = new Child()
child->parent = parent
unset(parent)
// memory for parent and child is still allocated!!!

// case 2
parent->child = new Child()
child->parent = parent
unset(child->parent)
unset(parent)
// memory for parent and child is freed
