In a more complicated example:

php Code:

$aArray = array('Apple', 'Orange', 'Kiwi', 'Pear');
$pItem =& $aArray[2];
$pItem = 'Pitaya';

As $pItem is now a reference to the third item in our array, changing its value will also change the value in the array, so Kiwi now becomes Pitaya.

Thanks, got that.
