 No,

<pre>
<?php
function debug($var) {
    print_r(debug_backtrace());
}

$foo = 10;
debug($foo);

?>
</pre>

 Output:

Array
(
    [0] => Array
        (
            [file] => /home/andyh/public_html/test.php
            [line] => 8
            [function] => debug
            [args] => Array
                (
                    [0] => 10
                )

        )

)

 If you can find "foo" in the above then it would do what the OP requested:
