Wassup guys, here is some php code I made for my website to count the amount of unique page views.I tried my best to explain each line of code with a comment above.

Create a new file "count.php" and add the following code: 

PHP Code:

<?php    /* get the IP address of the user */    $getra = $_SERVER['REMOTE_ADDR'];    /* Encrypt the IP address with sha1 in brackets; also get it ready for the next line with \n */    $printip = "<" . sha1($getra) . ">\n";    /* get the file name where we are printing our encrypted IPs */    $getfile = "ipfile.txt";    /* Open that file with read/write access; If it doesn't exist it will create it. */    $ipfile = fopen($getfile, "a+") or die("Unable to open file!");    /* count the amount of lines in the ipfile.txt(AKA: counting how many IP's are on the list) */    $countipfile = count(file($getfile));    /* read the file we opened */    $ipget = fread($ipfile, filesize($getfile));    /* if it contains the ip address already, do nothing.    If it doesn't have the IP address on file, write it & +1. */    if(strpos($ipget, $printip) !== false){    }else{        fwrite($ipfile, $printip);        /* since the new visitor wont see his view on the counter until he refreshes his browser; */        $countipfile++; /* We account for his IP that wasn't initially counted in the list by adding 1 (because it wasn't there) */        /* Once he refreshes, his IP is already on the list and counted. */    }    /* write the amount of unique visits. */    $theCount = "Unique Website Views: ". $countipfile . "";        ?>

Now, whatever page you want to record the amount of visitors on, add the following code (preferably to the head):
(So if someone views a page with this code in it, their IP will be logged)

PHP Code:

<?php include count.php; ?>

Now to print your unique page counter, use the following code (make sure the line of code above is included somewhere in the page):

PHP Code:

<?php echo $theCount; ?>

I hope you guys enjoy this, if you have any questions comment below and I will try to help you

i dont know what this does but this looks like it works
