Passing Object Refs throught Arrays

I'm having a problem, and I wrote this sample code to illistrate it. In this code, I'm trying to create a object, put it throught a que. I then want something to happen to this object, and this change to be reflected in the original object. I am aware that PHP uses copy symantecs not refrence ones, so I have used "&" at all the places I can see to use them. However it doesnt work: the output from this is still 0 not 100 as it should be. Does anyone have any suggestions, or URL's to really good guides on reference passing? Thanks in Advance, James. --------------------- class test { var $flag = 0; } // Make Object $root = new test(); // Make Que $que = array(); // Stick object on que array_push($que, &$root); // Take object from Que $consider =& array_shift($que); // Change something on the object we pulled from the que $consider->flag = 100; // Test and see if it changed on the original object echo($root->flag);
