[SOLVED] Updating file access time through php.

[mr_mind]

Alright so i have a script which reads to see if you are online based on the file access time of the file which contains your user id #, thr problem with this is that once the idle time (which is required) is up you are marked as logged out and cannot log back in again. All i eed to do is change the file access time every time a user views a page on my website while logged in. so if anyone knows a function which does this directly or indirectly it would be much appreciated.

Will touch() do it?

<?php
if (touch($FileName)) {
    echo "$FileName modification time has been changed to present time";
} else {
    echo "Sorry, could not change modification time of $FileName";
}
?>

solved with: touch(session_save_path() . '/sess_' . session_id());
