I've done all the debugging I could possibly do... I have a little chat script written in PHP that I've been playing around with.<br /><br />It works fine on my WinXP box, and on my Linux box, but I've tried it on two different web hosts including my account with TCH and I always get erros when the script tries to read or write to it's files. I could tweak it to use a database, but that would make it harder just to drop into a folder and have it work.<br /><br />The files are called 'chat.dat' to track what people are saying and 'active.dat' to track the talkative users. <br /><br />If I use fopen($chatfile, "a+"); it'll open the chat.dat file bu~t...it won't read or write anything to it... When I use the same thing on the active.dat file it only writes one user to the file...no more...no less...one is the number that it writes... <img src="http://www.totalchoicehosting.com/forums/style_emoticons/default/tongue.gif" style="vertical-align:middle" emoid="
" border="0" alt="tongue.gif" /> <br /><br />I'm very confused...any questions or answers? <img src="http://www.totalchoicehosting.com/forums/style_emoticons/default/biggrin.gif" style="vertical-align:middle" emoid="

Otherwise all the other scripts that write/read files on TCH servers would have the same issues. It just puzzles me that the script works fine on my own boxes...

Yay! Okay, here's the deal. When you open a file in 'a+' mode the file pointer is set to the end of the file, so when I tried to read back from the files I was opening I was ramming my script into a brick wall (past the end of the file). So, I called 'rewind($fp)' before both read operations and it's working now. <img src="http://www.totalchoicehosting.com/forums/style_emoticons/default/biggrin.gif" style="vertical-align:middle" emoid="" border="0" alt="biggrin.gif" /><br /><br />Don't ask me why it functions correctly under Slack and Win though...because now that I think about it, it shouldn't at all.... <img src="http://www.totalchoicehosting.com/forums/style_emoticons/default/huh.gif" style="vertical-align:middle" emoid=":huh:" border="0" alt="huh.gif" /> <br /><br />Nate<!--content-->
How do you specify the actual file name? I'm trying to use a simple counter file, and have had no success opening the file with:<br /><br /> $fp = fopen( $counterFile, "r+" ) or die( "Can't open counter file [$counterFile]" );<br /><br />It fails everytime. I know the file exists, although I can't seem to change the permissions from 644, but that's another issue.<br /><br /> I've also tried "r", "w", "a", and "a+" options with the exact same result. Do I have to give the full path? I've tried just "counter.txt", "www.ebackbid.com/counter.txt", "/home/ebackbid/public_html/counter.txt" and "public/counter.txt". I'm running out of permutations (and patience).<br /><br />Thanks,<br />Dorsey<!--content-->
