Need help with php

[dennylin93]

I need to create an invisible counter for my website with php or Flash, but I don't know how. Could anyone please teach me? I don't have access to any databases though. Thanks in advance.

There are a few steps. The first one is to check for and set a cookie, so that you don't count the same person twice. Start here for that:http://www.php.net/manual/en/features.cookies.phpYou will want to check the cookie when someone shows up, and if it is not there you will want to give them a cookie and update a text file with the count. So, the second step is to open the file, read it, and write it.You will want to use this function to read the counter file:http://www.php.net/manual/en/function.file-get-contents.phpLike this:

<?php $count = intval(file_get_contents("/path/to/counter.txt"));?>

And then use fwrite to write the new value back. This modified example is from the reference page for fwrite:

<?php$filename = 'test.txt';// Let's make sure the file exists and is writable first.if (is_writable($filename)) {   if (!$handle = fopen($filename, 'wb')) {		 echo "Cannot open file ($filename)";		 exit;   }   if (fwrite($handle, $count + 1) === FALSE) {	   echo "Cannot write to file ($filename)";	   exit;   }	    fclose($handle);} else {   echo "The file $filename is not writable";}?>
