As the title sugests , i have a functions , i make a few changes to an array( this array is my paramether ). Then i realized that i used a copy of my actual array.I know there was a way to get the actual array and not a copy , what was it ?Thank you all in advance , i know you will solve this in a jiffy 
Here is where i use it\[code\]function findChildren($listOfParents) { static $depth=-1; $depth++; foreach ($listOfParents as $thisParent) { $thisParent->title = str_repeat(" >", $depth) . $thisParent->title; $children = page::model()->findAll(array('condition'=>'parent = ' . $thisParent->id)); findChildren($children); } $depth--; }\[/code\]So i need this $listOfParents, not his copy.
