Hmm... How about SQL query JavaScript popup window? ;-)

Great. Could you submit a patch to the patch tracker so we can test it?

Afaik this is possible in PHP3, but I'm not sure. But I think we have
already used this in our code.

My ISP uses both on the webservers: .php3 files are parsed with PHP3
whereas .php files are parsed with PHP4.
At about 14:00 (CET), I'll test this.

Or you'd have to build a wrapper function that passes the parameters to
the correct function.
Something like:

function my_wrapper($param) {
    global $whatfunctiontouse;
    switch ($whatfunctiontouse) {
        case 'foo':
            return foo($param);
        case 'bar':
            return bar($param);
        case 'foobar':
            return foobar($param);
