| 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.
