A variable, which is referenced by another variable, is passed by value.
During the call, the original variable is updated. This should not affect func_get_arg().
--FILE--
<?php
function refVal($x) {
    global $a;
    $a = 'changed.a';
    var_dump($x);
    var_dump(func_get_arg(0));
}

$a = "original.a";
$ref =& $a;
refVal($a);
?>
