Your code actually works , maybe you are not printing the data that is why you are getting a blank page.
Tested
<?php
$url = file_get_contents("http://maps.googleapis.com/maps/api/geocode/json?address=Delhi&sensor=true");
$json = json_decode($url);
foreach($json->results as $item) {
$location_item = array(
'address' => $item->formatted_address,
);
}
print_r($location_item);
OUTPUT :
Array
(
[address] => New Delhi, Delhi, India
)
