counter problem

[Anon]

I have a simple counter on my page, it uses a text file to store the data, it's the one that I found everywhere on t he web but it won't work for me. The problem is it pulls the countnumber from the file, increments it, prints it, and then it is supposed to store the new countnumber. I think that is the problem. Here's my code:

<?php

$counter_file = "http://12.245.189.164/design/count.txt";


if (!($fp = fopen($counter_file, "r"))) die ("Cannot Open $counter_file.");


$counter = (int) fread($fp, 20);


fclose($fp);


$counter++;


echo "You are visitor Number $counter.";


$fp = fopen($counter_file, "w");


fwrite($fp, $counter);


fclose($fp);

?>

Not sure but it might depend what version of php you are running. Try replacing $counter++ with $counter = $counter + 1;

Um, unless you know something I don't, you can't WRITE to a file through the HTTP protocol as you try to do in your fwrite($fp, $counter) line. In order for this to work, you have to store the counter in a file local to your machine that your webserver has write access to.

If you need the file to be on a remote server, you'll have to look into something like editing the file locally and then using the PHP ftp commands to update the file on the remote server.
