edit TXT file if script is not there.

[xxshadowxx]

I want this script to instead of saying you're a guest, into deleting a line in a TXT file.

Is this possible?

Below is the script I'm using.

if(stripos(file_get_contents('http://www.othersite.com/page.html'), '<script')!== false)
echo('You\'re an affiliate.');
else
echo('You\'re a guest.')

EDIT:
also is it possible to "search" for a tag or something in the text code and delete it?

Welcome to Webmasterworld!

Have you tried str_replace [us2.php.net] or preg_replace [us2.php.net]? This is a good place to start.

Good luck!
