PHP Counter -- Session Control

After you set up the counter, you may find that counter will update whenever you refresh the page. That will lead incorrect hit counter.

Here is the fix of the above problems. We use session variable to keep track of each session which is browsing your page. One session counts as one hit.

In order to do this, we need add the following codes to graphcount.php.

Open graphcount.php in your favorite editor.

At the second line, right under <?php, add session_start();

Then find:

// If the log file exist lets read count from it
else {
$count = @fread($file, filesize($logfile)) or $count=0;
fclose($file);
// Raise the value of $count by 1
$count++;

Change to

// If the log file exist lets read count from it
else {
$count = @fread($file, filesize($logfile)) or $count=0;
fclose($file);
// Raise the value of $count by 1
if (!isset($_SESSION['count']))
{ $_SESSION['count'] = 0;
$count++;}

See the code in red. It checks the existence of session variable "count" , if it exists, it means this session is already taken into account. Otherwise add 1 more to our counter.
