Getting Facebook event venue latitude & longitude - php

Question

Hello I use the following code in order to retrieve an events infoormation from facebook based on the url provided.
The code is this:
function importEvent($url)
{
$facebook = new Facebook(array(
'appId' => 'someAppId',
'secret' => 'someSecret',
'cookie' => true, // enable optional cookie support
));
if(checkLogin()==true)
{
//get rid of hash if exists
$hash = explode('#',$url);
if(!empty($hash[1]))
$array = parse_url($hash[1]);
else
$array = parse_url($hash[0]);
parse_str($array['query'],$output);
$eid = $output['eid'];
if(empty($eid))//new url think http://www.facebook.com/events/2323423423423/
{
$url = str_replace('http://www.facebook.com/events/','',$url);
$url = str_replace('https://www.facebook.com/events/','',$url);
$hash = explode('/?',$url);
if(!empty($hash[1]))
$url = $hash[0];
$eid = str_replace('?','',$url);
$eid = str_replace('/','',$url);
//print_r($eid);
}
//Calling users.getinfo legacy api call example
try{
$param = array(
'method' => 'events.get',
'eids' => $eid,
'access_token' => $_SESSION['access_token']
);
$events = $facebook->api($param);
}
catch(Exception $o){
error_log($o);
echo $o;
}
print_r($events);
return $events;
}
}
The output I'm getting is this:

)
However on the api documentation it mentions that venue contains the following:
The location of this event
generic access_token, user_events or friends_events
object containing one or more of the following fields: id, street, city, state, zip, country, latitude, and longitude fields.
But all I'm getting is the venue id.
I couldn't locate a specific piece of information on how to retrieve lat + lng of a venue place and I assume that this code is ok if I'm not mistaken.
Do I need to execute another query just for the venue info and if so could you please provide any reference or code examples? Or is there a way for this piece of code to return the lat + lng also, so I wont have to do 2 queries for 1 event?

After some research I've found that that this could be doen with fql.multiquery and it seems to work fine now. Here is the source code.
function importEventFQL($url)
{
$facebook = new Facebook(array(
'appId' => 'someApddID',
'secret' => 'someSecret',
'cookie' => true, // enable optional cookie support
));
if(checkLogin()==true)
{
list($url_static,$url_URI) = explode('/events',$url);
$url_URI = ltrim($url_URI,'/');
list($eid, $trash) = explode('/?',$url_URI);
$fql = '{';
$fql .= '"event_info":"SELECT name, description, pic_small, pic_big, eid, venue, location, start_time, end_time, host from event WHERE eid=\'' . $eid . '\'",';
$fql .= '"event_venue":"SELECT name, username, page_id, location FROM page WHERE page_id IN (SELECT venue.id FROM #event_info)"';
$fql .= '}';
$param = array(
'method' => 'fql.multiquery',
'queries' => $fql,
'callback' => ''
);
$result = $facebook->api($param);
print_r($result);
}
}

If you want just the FQL to do this:
{
"events" : "SELECT privacy, name, description, start_time, venue.id, pic_cover FROM event WHERE eid IN (SELECT eid FROM event_member WHERE uid = me())",
"venues" : "SELECT latitude, longitude, name, page_id FROM place WHERE page_id IN (SELECT venue.id FROM #events)"
}
