capturing the output to a file rather than the browser

Hi, Wondering if anyone can help!. I am trying to run a file like this after a submit from a form. <form action="showmatches.php" target="new"> .. .. </form> My question is! Is there anyway using PHP to capture the output that is displayed above in a new window when the 'showmatches.php' is run to a file instead. Kinda like viewing the source once in the browser but instead it's going straight to a file on the server automatically. Thanks, Brent.
