[PHP] PHP can't access txt files (but TCL can..??)
TCL 1, PHP 0 Ok, I am frustrated.. here is my code and this portion has to be done in PHP. I have a frame that can only be accessed if 1 of 2 things occur: 1) if $HTTP_REFERER has a specific value 2) if your nickname passed in the query string is found in the existing nicknames.txt file found in /chat/nicknames.txt Here is the code: http://"; . $SERVER_NAME . "/chat/chat_login.php'>\n"; echo "\n\n\n"; } } ?> No matter what I do, however, the file cannot be accessed if it exists and causes damage galore. Can anyone out there help me figure out what I did wrong; I'm completely stumped and may have to rewrite this portion of the chatroom in TCL, all of my TCL scripts have had NO problems whatsoever accessing the txt files.

Notes:
o What version of PHP?
o Is register_globals on or off? i.e. are you sure $DOCUMENT_ROOT
has a value and that you're not trying to open '/chat/nicknames.txt'?
o Quote the 'r' in the fopen() call.
o Try this all with error_reporting(E_ALL) and fix (not with '@')
everything it complains about.
o Your second regex checks that $contents contains at least one alpha-
numeric or an underscore or a hyphen. Looks like it should be
checking that the string contains *only* those characters.
o fread() takes 2 parameters, not one.
o 'damage galore' doesn't tell us anything. What *exactly* is the
current result of running the below?
