I am getting blank page the code doesn't work please help i am new to php

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
)
