you could however always call:
$a->__destruct(); that would also kill $b and $c

If you want to delete an object, when you have other references to it, you must use the & operator, otherwise the object will not be killed for all references.
I tested without the &-operator, but that did not work
The &-operator is still important in PHP5. Look at the folling example
<? $a = new stdclass; $b = $a; $c =& $a; ?>
unsetting a will only kill a, b and c will still be "alive". setting a to null will kill c but not b

Can anuyone describe this error?
Compile Error: E:\Source\CMAES\src\include\dom.inc.php line 67 - Declaration of CMAES_DOM_Node_List::item() must be compatible with that of CMAES_DOM_Node_List_Interface::item()
// {{{ interface CMAES_DOM_Node_List /** * * @access public */ interface CMAES_DOM_Node_List_Interface { function item();
I think you have to also define the arguments you want to use for item() in
your interface:
function item($a_iIndex);
function search(); function addItem(); function removeItem(); } // }}} /** * CMAES_DOM_Node * */ class CMAES_DOM_Node_List implements CMAES_DOM_Node_List_Interface { // {{{ properties /** * Number of elements in node list * @var integer */ public $iLength = 0;
/** * Nodes in list * @var array */ private $_aNodes = array(); // }}}
// {{{ item /** * Returns the nth index given in item. * * @param inte $a_iIndex - index in list * @return mixed node object or null if item was not found * @access public */ function &item($a_iIndex)
Are you sure you need '&' here? Shouldn't PHP5 pass all variables by reference on default?
