Read status of LM1200

I don't know if anyone will be interested, but here is my hacked up code for pulling the session details from my LM1200.

I plan to have this script run on my web server and build a pretty graph that will be saved as HTML for my other computers to display so they are not all requesting updates directly from the LM1200.

<?php
$ipaddress = "192.168.5.1";
$cookiefile = "cookie.txt";
$password = "password";


function InitializeCurl($cookiefile) {
	$curl = curl_init();
	curl_setopt($curl,CURLOPT_COOKIEJAR,$cookiefile); //file for saving cookie data
	curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,false); //this is local traffic - don't bother with SSL verification
	curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,false); //this is local traffic - don't bother with SSL verification
	curl_setopt($curl,CURLOPT_USERAGENT,"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
	curl_setopt($curl,CURLOPT_RETURNTRANSFER,true); //always want to capture result to string
	curl_setopt($curl,CURLOPT_HEADER,false); //leave headers out of result string
	return($curl);
}


function GetToken($curl,$ipaddress) {
	$url = "http://$ipaddress";

	curl_setopt($curl,CURLOPT_URL,$url);
	curl_setopt($curl,CURLOPT_FOLLOWLOCATION,true); //Let LM1200 forward to /index.html

	$result = curl_exec($curl);

	//Extract token from result
	$n = preg_match('/\"token\" value=\"([^\"]+)/',$result,$match);
	if ($n>0) { $token = $match[1]; } else { $token = ""; }
	return($token);
}


function DoLogin($curl,$ipaddress,$token,$password) {

	$data = 'token=' . $token . '&ok_redirect=%2Findex.html&err_redirect=%2Findex.html&session.password=' . $password;

	curl_setopt($curl,CURLOPT_URL,"http://{$ipaddress}/Forms/config");

	$result = curl_exec($curl); //discard results - this will set the session as logged in
}


function GetJson($curl,$ipaddress,$token) {
	curl_setopt($curl,CURLOPT_FOLLOWLOCATION,false); //don't follow redirects for json calls
	curl_setopt($curl,CURLOPT_HTTPHEADER,array( //simulate headers captured from chrome developer mode

	));

	curl_setopt($curl,CURLOPT_POST,false); //force cURL back to GET
	curl_setopt($curl,CURLOPT_POSTFIELDS,''); //force cURL back to GET
	curl_setopt($curl,CURLOPT_CUSTOMREQUEST,'GET'); //force cURL back to GET

	$randomnum = rand(0,65535); //my guess is that this is a random number to prevent caching?
	curl_setopt($curl,CURLOPT_URL,"http://{$ipaddress}/api/model.json?internalapi=1&x={$randomnum}");
