a php script to get lat/long from google maps using CellID
- by user296516
Hi guys,
I have found this script that supposedly connects to google maps and gets lat/long coordinates, based on CID/LAC/MNC/MCC info.
But I can't really make it work... where do I input CID/LAC/MNC/MCC ?
<?php
$data =
"\x00\x0e". // Function Code?
"\x00\x00\x00\x00\x00\x00\x00\x00". //Session ID?
"\x00\x00". // Contry Code
"\x00\x00". // Client descriptor
"\x00\x00". // Version
"\x1b". // Op Code?
"\x00\x00\x00\x00". // MNC
"\x00\x00\x00\x00". // MCC
"\x00\x00\x00\x03".
"\x00\x00".
"\x00\x00\x00\x00". //CID
"\x00\x00\x00\x00". //LAC
"\x00\x00\x00\x00". //MNC
"\x00\x00\x00\x00". //MCC
"\xff\xff\xff\xff". // ??
"\x00\x00\x00\x00" // Rx Level?
;
if ($_REQUEST["myl"] != "") {
$temp = split(":", $_REQUEST["myl"]);
$mcc = substr("00000000".dechex($temp[0]),-8);
$mnc = substr("00000000".dechex($temp[1]),-8);
$lac = substr("00000000".dechex($temp[2]),-8);
$cid = substr("00000000".dechex($temp[3]),-8);
} else {
$mcc = substr("00000000".$_REQUEST["mcc"],-8);
$mnc = substr("00000000".$_REQUEST["mnc"],-8);
$lac = substr("00000000".$_REQUEST["lac"],-8);
$cid = substr("00000000".$_REQUEST["cid"],-8);
}
$init_pos = strlen($data);
$data[$init_pos - 38]= pack("H*",substr($mnc,0,2));
$data[$init_pos - 37]= pack("H*",substr($mnc,2,2));
$data[$init_pos - 36]= pack("H*",substr($mnc,4,2));

if ((hexdec($cid) > 0xffff) && ($mcc != "00000000") && ($mnc != "00000000")) {
$data[$init_pos - 27] = chr(5);
} else {
$data[$init_pos - 24]= chr(0);
$data[$init_pos - 23]= chr(0);
}
$context = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/binary\r\n"
. "Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);
$xcontext = stream_context_create($context);
$str=file_get_contents("http://www.google.com/glm/mmap",FALSE,$xcontext);
if (strlen($str) > 10) {
$lat_tmp = unpack("l",$str[10].$str[9].$str[8].$str[7]);
$lat = $lat_tmp[1]/1000000;
$lon_tmp = unpack("l",$str[14].$str[13].$str[12].$str[11]);
$lon = $lon_tmp[1]/1000000;
echo "Lat=$lat <br> Lon=$lon";
} else {
echo "Not found!";
}
?>
also I found this one http://code.google.com/intl/ru/apis/gears/geolocation_network_protocol.html , but it isn't php.
