Without paying attention to your code, how is the CMOD declared?
If your website has a control panel, like mine, you can declare 666 on the text file you wanna write on yourselve.

Without this rights, your script will never work.
One reason never host your php driven sites at hosting companies which you have to call each time you you wanna change something.

CHMOD is the security clearence that users have to a file. It's split into three sectors; You, group and users. You is obviously you, Group is other people with access to the site, and users is the general public.
For each of the sectors there are three limitations you can place on a file; Read, Write an Execute. If you want to write to a text file, you'll have to select Read and Write (and maybe Execute) under the 'you' sector. You can do this in an FTP client such as WSFTP or look on google there are loads of tutorials on CHMOD there.

Hope this helps

Actually, which error message do you get and what version of PHP, web server and operating system is the script tested on?

Changing file permissions with chmod is only applicable on *nix systems.
