Installing PHP4 to run the following script

I am trying to install PHP4 on my server to run the following script so that it emails me my visitors IP address, the search term they used to visit my page and their browser type. I'm running BSD on my server and I typed in vinstall php4, what do I do next?

Here is the page that I am using. Right now it is just sending me and email that says.

Referer Page:
Referer IP address:
User Agent:


<?
//*****1a.php
//This program mails visitor id to null@void.com, then sends to download site

$to="tim@lablvr.com";
$from="tim<null@void.com>";
$dt=date("Y-m-d H:i:s");

// Mail Subject Part

$subject=$id;

// --------
// enquiry form details sent to marketing dept....!

mail($to, $subject,
"$id
Referer Page:$HTTP_REFERER
Referer IP address:$REMOTE_ADDR
User Agent:$HTTP_USER_AGENT
",

"From:$from");
// The email part ends here...!

header("Location:http://www.void.com/");
?>
--end report--

Well, if it is sending the emails it means that it is somewhat working, isn't it? :-)

Actually your problem is related to the register_globals setting.

solution 1:
Just edit your php.ini (usually /usr/lib/php.ini, but for bsd it must be somewhere under /usr/pkg.. i'm sure you'll guess it)
If you don't have it, create one from templates and set register_globals to ON.

solution 2:
change your variables to $_SERVER['REMOTE_ADDR'] etc.

I have to say that the use of register_globals is not a good idea.

Much better to use the $_xxxx super globals.
