After finishing using an object I can free up resources by unsetting the object eg.: $object = new ClassName(); $var = $object->DoSomething(); unset($object); However if I use a singleton instance of the class eg. $var = ClassName::GetInstance()->DoSomething(); there doesn't appear to be anything to unset, but surely the instance must take up some resources? Does the instance disappear when the script terminates? I assume the instance has a lifetime corresponding to the page which calls it and is destroyed when the page is closed, but is it possible or necessary to remove the instance from memory before the page is closed? And if so how? I have been unable to find anything on the net that deals with this issue so any help on this subject would be much appreciated.
