Help debug php user tracking script.

[djkee]

Hello everyone, i have this script that i am trying to implement to work on my website and the script is suppose to track what games are being played at the moment but the only problem is that every time it records in the .txt file the script would erase everything else in the file and just write a new line and i want the script to keep all the other records in the file.

 

What the script does:

Records the gameID, gamename, gamethumb url, IP and time all separated by |.

Example: 1744|The Simpliest Snowboarding|The Simpliest Snowboarding|77.88.42.26|1264717552

 

Look for the IP and if already exists update the record with the new info.

If the IP does not exist already write a new line with the information.

If the record is older then 60min erase it.

 

Its just a simple script that i will use to show what people are currently playing on the website.

 

Here is the script:

$dataFile = "visitors2.txt";

$sessionTime = 60; //this is the time in **minutes** to consider someone online before removing them from our file

//Please do not edit bellow this line

error_reporting(E_ERROR | E_PARSE);

if(!file_exists($dataFile)) {
   $fp = fopen($dataFile, "w+");
   fclose($fp);
}
$game2id = $this->get_template_vars('gameId');
$gamethumb = $this->get_template_vars('gameFilename');
$ip = $_SERVER['REMOTE_ADDR'];
$gamename = $this->get_template_vars('gameName');
$users = array();
$onusers = array();

//getting
$fp = fopen($dataFile, "r");
flock($fp, LOCK_SH);
while(!feof($fp)) {
   $users[] = fgets($fp, 32);
}
flock($fp, LOCK_UN);
fclose($fp);


//cleaning
$x = 0;
$alreadyIn = FALSE;
foreach($users as $key => $data) {
//list( , , , $lastvisit) = explode("|", $data);
list( , , , , $lastvisit) = explode("|", $data);
   if(time() - $lastvisit >= $sessionTime * 60) {
      $users[$x] = "";
   } else {
      if(strpos($data, $ip) !== FALSE) {
         $alreadyIn = TRUE;
         $users[$x] = "|$game2id|$gamename|$gamethumb|$ip|" . time(); //updating
      }
   }
   $x++;
}

if($alreadyIn == FALSE) {
   $users[] = "$game2id|$gamename|$gamethumb|$ip|" . time();
}

//writing
$fp = fopen($dataFile, "w+");
flock($fp, LOCK_EX);
$i = 0;
foreach($users as $single) {
   if($single != "") {
      fwrite($fp, $single . "\r\n");
      $i++;
   }
}
flock($fp, LOCK_UN);
fclose($fp);

 

I hope somebody can help me
