get data from external url using php json?

Question

I'm trying to extract data from an external url using json in PHP using the following code:

<?php
error_reporting(-1);
ini_set('display_errors', 'On');
$url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=37.76893497,-122.42284884&sensor=false";
$json = file_get_contents($url);
$json_data = json_decode($json, true);
echo $json_data["formatted_address"];
?>

however, I get nothing on my page. in fact, i get this error:

Notice: Undefined index: formatted_address on line 7

is there something I'm missing?

any help would be greatly appreciated.

@Jigar, thanks, var_dump($json) prints the entire the content of the URL on my page now. — H.HISTORY

Please update your question with var_dump($json)'s output. — Jigar

'formatted_address' is a key of the main array 'results', so you should loop $json_data['results'] and search for the key 'formatted_address'.

You are not providing proper INDEX. Proper INDEX is $json_data['results'][0]['formatted_address']; for 1st result.

Use foreach loop to print all address.

Try

$url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=37.76893497,-122.42284884&sensor=false";
$json = file_get_contents($url);
$json_data = json_decode($json, true);

foreach($json_data['results'] as $item)
{
    echo $item['formatted_address']."<br />";
}
