Extracting lat and long from google map json

Hello Guys,

I need some help here.. I am trying to extract the lat and long from a json query from google.

Here is what I receive back from json

{
"name": "795PollardBlvdSW,Atlanta,GA",
"Status": {
"code": 200,
"request": "geocode"
},
"Placemark": [ {
"id": "p1",
"address": "Atlanta, GA, USA",
"AddressDetails": {
"Accuracy" : 4,
"Country" : {
"AdministrativeArea" : {
"AdministrativeAreaName" : "GA",
"SubAdministrativeArea" : {
"Locality" : {
"LocalityName" : "Atlanta"
},
"SubAdministrativeAreaName" : "Fulton"
}
},
"CountryName" : "USA",
"CountryNameCode" : "US"
}
},
"ExtendedData": {
"LatLonBox": {
"north": 33.8231844,
"south": 33.6747422,
"east": -84.2599230,
"west": -84.5160418
}
},
"Point": {
"coordinates": [ -84.3879824, 33.7489954, 0 ]
}
} ]
}


Here is the code I am using


$geocode=file_get_contents('http://maps.google.com/maps/geo?output=json&q=795PollardBlvdSW,Atlanta,GA');

$output= json_decode($geocode);

$lat = $output->results[0]->geometry->location->lat;
$long = $output->results[0]->geometry->location->lng;

echo $lat;
echo $long;


Just not sure how to pull the lat and long out of a json into vars..

Please advise..

I'm not familiar with the Google Maps API,

but it looks to me as if in the general case, the lat and long would be extracted by:


$geocode=file_get_contents('http://maps.google.com/maps/geo?output=json&q=795PollardBlvdSW,Atlanta,GA');

$output= json_decode($geocode);

//Extract the placemark data into two arrays $long and $lat.
$long = $lat = array();

foreach ($output->Placemark as $i => $placemark)
list($long[$i], $lat[$i]) = $placemark->Point->coordinates;

var_dump($lat);
var_dump($long);


The first number is long, then lat because 33 deg. North, 84 deg. West sounds about right for a city somewhere in the United States. (I have no idea where Atlanta actually is though, I've never been to the USA!)

I just got the fix and it is I had this wrong

$lat = $output->Placemark[0]->Point->coordinates[1];
$long = $output->Placemark[0]->Point->coordinates[0];


It's working fine now! Thanks for your help!
