As said before, references aren't pointers. That means, the following construct won't do what you expect:
<?php
function foo (&$var)
{
$var =& $GLOBALS["baz"];
}
foo($bar);
?>What happens is that $var in foo will be bound with $bar in caller, but then it will be re-bound with $GLOBALS["baz"]. There's no way to bind $bar in the calling scope to something else using the reference mechanism, since $bar is not available in the function foo (it is represented by $var, but $var has only variable contents and not name-to-value binding in the calling symbol table).
