Re: Returning reference problem

Starting over since my last thread had too little effort put in it. I have this script that should create a multi-demensional array that would resemble a directory structure. The problem is that after adding one element to a "folder" it appears to be creating a new object instead of adding another item to the current object. So there can only be one "file" or "folder" in the parent "folder" with the exception of the top level. My entire script is below. Thanks, Jon <? class dir { var $name; var $subdirs; var $files; var $num; var $prio; function dir($name,$num,$prio) {

    $this->name = $name;     $this->num = $num;     $this->prio = $prio;     $this->files = array();     $this->subdirs = array();   }

function addFile($file) {

    $this->files[] =& $file;     return $file;   }
