note 35188 added to function.fwrite

Is there any kind of security risk to using fwrite? I wrote a script that logs HTTP header information (User Address and Referer) and lately I've been noticing a small, subtle change to my site. All my textboxes have rounded corners. When I think I've been hacked, it's because the rounded corners are gone. Basically, there are two specific lines of code that need to be changed (not removed completely) in order to do this. When it happens, it's obvious it's not a glitch, because it's too specific, non-random. ---- Manual Page -- http://www.php.net/manual/en/function.fwrite.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35188 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35188&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35188&report=yes
