This script doesn't take too much explaining :P
It counts an individuals clicks (respectively to their IP)

ok so;

1 Run this SQL Query in your database manger;

CREATE TABLE `ip_hits` (
`ip` VARCHAR( 255 ) NOT NULL ,
`clicks` VARCHAR( 255 ) NOT NULL ,
`date` VARCHAR( 255 ) NOT NULL
) TYPE = MYISAM ;

2 Place the snippet into your header/general variable page (and continue to use;

include("webpage.php");

)
or, if you do not have a page like that, make a new webpage, call it hits.php or something, and at the top of each page you want the hits to be counted, add

include("hits.php");

3 Make a new webpage called 'hits_viewer.php' and insert this code;

<?php
include("database_connect_file.php");
$sql = mysql_query("SELECT * FROM `ip_hits`");
while ($hit = mysql_fetch_array($sql)) {
  echo $hit["ip"]. ' - ' .$hit["clicks"]. ' (Last visit: ' .$hit["date"]. '<br>';
}
?>

of course, you may edit that into your website's style etc. this is just some code to show an outline of how it can be done ;-)

[i]As a sidenote, if you want, as a footer or something, to show the total number of visitors, yoou can use a code something like this;

$hits = mysql_query("SELECT * FROM `ip_hits`");
$hits = mysql_num_rows($hits);
echo "Visitors: " .$hits;

note, not 100% accurate as, ofc, IPs can change from time to time

Post any bugs/errors(;-s)/comments. thanks :-)

Ima put a webpage counter script on next if that would be any better for any of your uses :-)

<?php

$date = gmdate(j);
$month = gmdate(F);
$sup = gmdate(S);
$year = gmdate(Y);
$datestamp = $date. '' .$sup. ' ' .$month. ' ' .$year. '';
$ip = ($_SERVER['HTTP_X_FORWARDED_FOR'])
      ?  $_SERVER['HTTP_X_FORWARDED_FOR']
      :  $_SERVER['REMOTE_ADDR'];

$hit_sql = mysql_query("SELECT * FROM `ip_hits` WHERE `ip` = '" .$ip. "'");
if (mysql_num_rows($hit_sql) == "0") {
  mysql_query("INSERT INTO `ip_hits` ( `ip` , `clicks` , `date` ) VALUES ('" .$ip. "', '1', '" .$date. "')");
}
else {
  $hit = mysql_fetch_array($hit_sql);
  $new_hits = $hit["clicks"] + 1;
  mysql_query("UPDATE `ip_hits` SET `clicks` = '" .$new_hits. "', `date` = '" .$datestamp. "' WHERE `ip` = '" .$ip. "'");
}

?>
