Keith, thanks... no luck doing it that way either... Can someone else
try the snippet and see what is returned?

php > $a = "/home/user/public_html/Packages/temp";
php > $b = array('' => '');
php > echo strtr($a, $b);
php > echo $a;
/home/user/public_html/Packages/temp
php > print_r($b);
Array
(
    [] =>
)
