Object problem

I just wrote this message in the wrong list so i'll be short... I have two classes: - mysql_connection - data_collection data_collection REQUIRES a mysql_connection object to work. So i decided to pass this object in the constructor for the data_collection, but when i do so it seems it creates a copy of this object and doesn't use the object i had previously created... I tried to do function data_collection(&$mysql_server){ ... } But even the & sign like they say to use on the php.net web site doesn't work, it creates a copy of the object. The only way i found to bypass this problem is to do: my_collection->mysql_server = &$mysql_server; which will assign a reference of the mysql_collection object to my collection, but this means i need to modify something like 45 files of my web site and also i have to add some init settings because they where done in the constructor where you needed the connection... please help me out!!!
