title: create visitor unique ID?
body: <p>I plan to create visitor unique ID and named as log file, as existing now I use the IP visitor as log file name i.e. logs/127.0.0.1.php but I think this is not <strong>enough</strong> because some visitor using share an IP address for PC's.</p>
  
  <p>The visitor log file itself as setting place of configuration of visitors itself, so I plan to add another unique ID to identify each different visitor so let's say the log file:
  logs/127.0.0.0.1-t3451dq.php, -t3451dq as unique ID
  so as long as visitor browsing on my website the unique log file as setting configuration for each user (because I use plain text)</p>
  
  <p>Currently I use:</p>
  
  <pre><code>&lt;?
  $filename = "./logs/".$_SERVER['REMOTE_ADDR'].".php" ; //out put logs/127.0.0.1.php
  $data stripcslashes($data);
  // each Visitor configuration here...
  // bla...bla...
  
  /* Writing file configurations */
      $buat = fopen($filename, "w+");
      fwrite($buat, "$data");
      fclose($buat);
  ?&gt;
  </code></pre>
  
  <p>so I need $filename add the $unique ID as name of their log file. Any ideas how to do that?</p>
