note 11285 added to Funktionsparameter

I contribute the following example with a specific use of "arguments by reference". function do($Param) { DoSomethingMore(&$Param); } $Value = 'Test'; do(&$Value); It seems to me that it is not described here how PHP handles "multiple" references. I try to use references to avoid unnecessary copying of objects. http://www.php.net/manual/de/functions.arguments.php
