Landmark to sql database using lsl and php??

First, thanks for all the help in advance. I am creating a vendor system - to learn, I know there are plenty out there - and I want each vendor to send its location, basically a landmark, to my database - I have been searching the wiki, but haven't had much luck. I tried llDetectedPos, and a few other things with no luck - any suggestions for basically recording where an object is and sending that to the sql database. I know how to send the information using php and sql, I have done it for many things, but need help with the landmark and LSL. Also, I was playing around with parcel name, parcel owner, parcel description, if I could send that too, that would be cool, but I couldn't get that to work. Here is the script I have with some information blocked out.

This script works, I just need to add the parts listed above.

default
{
state_entry()

{
llSetText( " ", < 1,1,1>, 1 );
}

touch_start(integer total_number)

{


string name;
string uuid;
string landmark;

name = llDetectedName(0);
uuid = llDetectedKey(0);
landmark = ???????;

key http_request_id;

http_request_id = llHTTPRequest( "http://www.blockedout.info/blockedout.php", [HTTP_METHOD,"POST",HTTP_MIMETYPE,"application/x-www-form-urlencoded"], "name=" + name + "&uuid=" + uuid);
}

}

You do not need to have the vendor send it's current location, Second Life does that for you by providing the appropriate headers in the request: http://wiki.secondlife.com/wiki/LlHTTPRequest

Specifically, it provides the X-SecondLife-Region and X-SecondLife-Local-Position headers.

Depending on your hosting provider and how the web server is configured, those headers might have to be accessed by another name. For instance, the way my setup is configured, I need to use code like the following to get the region info:

$simheader = $_SERVER['HTTP_X_SECONDLIFE_REGION'];

I think that there are numerous examples available, but I will see if I can dig up something more detailed.

.

See this page for more examples of both the LSL and corresponding PHP: http://rpgstats.com/wiki/index.php?title=ExamplellHTTPRequest

Keep in mind that you might have to make modifications depending on whether PHP is compiled as an apache module, like changing

$headers = apache_request_headers();
 $region = $headers["X-SecondLife-Region"];

to this :

$region = $_SERVER['HTTP_X_SECONDLIFE_REGION'];

Exactly what I am looking for!
