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?
