|| Hi,
||
|| Using PHP 4.4.4, and I have this class
||
|| class CUserItem {
|| var $m_id;
|| var $m_children_arr;
|| function CUserItem($p_id)
|| {
|| $this->m_id = $p_id;
|| $this->m_children_arr = array();
|| } // CUserItem
|| function addChild($p_child) {
|| array_push($this->m_children_arr, $p_child);
|| } // addChild
|| function numChildren() {
|| return count($this->m_children_arr);
|| } // numChildren
|| } // CUserItem
||
|| I have an associative array of objects, but am getting errors trying
|| to call a method
||
|| $items_arr = array();
|| $items_arr[0] = new CUserItem(1);
|| $item = &$items_arr[0];
|| print $item->numChildren(); // produces an error
||
|| The error produced is "Fatal error: Call to a member function on a non-
|| object in /usr/local/apache2/htdocs/portal/show_toc.inc on line 77".
|| I need to get the object by reference because I will be manipulating
|| it later on. What am I doing wrong above?

| print_r on $items_arr[0], then print_r on $item after it is set by ref to
| $items_arr[0]. finally print_r on $item after $item is set to
$items_arr[0]
| by value. therein lies the difference.


btw, i'd also go about it differently. i'd do $item = new CUserItem(1) and
then add it to the $items_arr. i know that this doesn't solve your problem,
as you still need to eventually iterate the array and successfully call
numChildren...but i must mention it all the same.
