<?php function foo(&$var) { $var =& $GLOBALS["baz"]; } foo($bar); ?> Let's re-write the above snippet of code in another way <?php $bar = &$var; // At this time, $bar refers to the content to which $var refers which is NULL or empty $var = & $GLOBALS["baz"]; // At this time, $var changes to refer to another content to which global $baz variable refers. However $bar is still refers to the content of NULL Expected Result: $bar will hold the content of $var (which is now the content of $baz) Actual Result: $bar holds a content of NULL or empty.
