And then do 'echo $foo' *before* you 'echo $bar'? The point you're trying to make is surely expressed better like this: <?php $foo = 'Bob'; // Assign the value 'Bob' to $foo $bar = &$foo; // Reference $foo via $bar. $bar = "Dave"; // Alter $bar... echo $bar; echo $foo; // $foo is altered too. ?> Clearer for the newcomer to programming, ne? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16738&edit=1
