I needed this for a test, but I'm too lazy to use MySql, so I made this.

First create a "testFile.txt", and enter "0" (without quotes) in it. Then add this in a php file.

PHP Code:

<?php
$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, 5);
fclose($fh);
intval($theData);
$theData = $theData + 1;

$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $theData);
fclose($fh);
echo $theData;
?>
