Script seems to just Stop!

Hello comrades,

I have been using a script provided by someone else, but it just seems to stop and I can't find why.  Can anyone take a look and see what my problem might be, thanks :

I receive no errors at all.  P.S. I'm using php v4.4.8 on Apache 2.0.64 Win XP

Thanks.

Well it could be any number of reasons.

Without an error there's no way of knowing.

Try turning on error reporting :

ini_set('display_errors', E_ALL);

Cheers,

Sussed it now, didn't have the libxml library available to php 4.
