Extracting Your Own Location Information From Google

location.php

// Today's time is needed to get the bounding for the request
$currentTime = time();

// Beginning and end of the day
$startTime = strtotime("midnight", $currentTime);
$endTime = strtotime("tomorrow", $startTime);

$smon =  date("m", $startTime)-1;
$sday = date("d", $startTime);
$syear = date("Y", $startTime);

$emon =  date("m", $endTime)-1;
$eday = date("d", $endTime);
$eyear = date("Y", $endTime);
 
 
//pb=!1m8!1m3!1iYYYY!2iMM!3iDD!2m3!1iYYYY!2iMM!3iDD
//The Google Location history URL - gets the KML.
$locationURL = "https://www.google.com/maps/timeline/kml?authuser=0&pb=!1m8!1m3!1i".$syear."!2i".$smon."!3i".$sday."!2m3!1i".$eyear."!2i".$emon."!3i".$eday;
 
//To request the file, using PHP, we need to tell curl where the cookies are.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $locationURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
 
$kml = curl_exec($ch);
curl_close($ch);

//get last gx:coord
$startIndex = strripos($kml,"<gx:coord>") + strlen("<gx:coord>");
$endIndex = strripos($kml,"</gx:coord>");

$substr =  substr($kml, $startIndex, $endIndex - $startIndex);
$latlngArr = explode(" ",$substr);
$lng = $latlngArr[0];
$lat = $latlngArr[1];

Sadly Google API doenst support this method anymore.

Personally switched to using GpsLogger (open source)
