It's not hard to write a function that does as such without the use of a
structure like that, though I can't see it being bad to have-- example:

function export_script_vars($var_names) {
        $result = "";
        foreach ($var_names as $var_name) {
                $result .= '<input type="hidden" name="$var_name" value="${$GLOBALS["$var_name"]}" /><br />
        }
        return $result;
}

This works provided that you are calling this from the top-level, and if
not, you have to export your variables out to the top level with $GLOBALS.
It should work, though.
