Visitor Logger (Web/Basic)

Notes

I was asked to log visitors for a two-day event a while ago, and then asked if the scripts I used could be given to original users. Being very simple scripts, I didn't want to charge for these, and so I've decided to make them public.

Use:

Upload the server side script to your web server, and place the LSL script a phantom prim in SL - the script will turn the prim invisible if it is not already. Ideal placement may be a small prim at waist height at a telehub, or at floor level covering a large area where users might walk through. You will need to edit the LSL script with the appropriate URL for your server.

Serverside script:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
   <TITLE>Simple Visitor Logger</TITLE>
</HEAD>
<BODY LINK="#0000FF" VLINK="#800080">
<?php
 
$name = htmlspecialchars($_GET['name']);
$object = htmlspecialchars($_GET['object']);
$key = htmlspecialchars($_GET['key']);
$ip = $_SERVER['REMOTE_ADDR'];
$ref = $_SERVER['HTTP_REFERER'];
$dtime = date('r');
if($ref == ""){
   $ref = "None";
}
if($name == ""){
   $name = "anon";
}
?>
Hello <?php echo  $name ?>.
thank you for visiting.
<?php
$entry_line = "$dtime - IP: $ip | name: $name | key: $key | object: $object\n";
$fp = fopen("visitors.txt", "a");
fputs($fp, $entry_line);
fclose($fp);
?>
 
 
</BODY>
</HTML>

The text file, "visitors.txt" must have write permissions.
