    This code will help in finding the latitude and longitude of any place using curl and php.

    Step 1: Finding the latitude and longitude for first place.

    <?php
ini&#95;set('error&#95;reporting', E&#95;STRICT|E&#95;ALL);
ini&#95;set('display&#95;errors', 1);

$address1 = "shastri nagar Dehradun";
$region = "India";
$address = str&#95;replace(' ','+',$address1);

$url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region";

$ch = curl&#95;init();

curl&#95;setopt($ch, CURLOPT&#95;URL, $url);
curl&#95;setopt($ch, CURLOPT&#95;RETURNTRANSFER, 1);
curl&#95;setopt($ch, CURLOPT&#95;PROXYPORT, 3128);
curl&#95;setopt($ch, CURLOPT&#95;SSL&#95;VERIFYHOST, 0);
curl&#95;setopt($ch, CURLOPT&#95;SSL&#95;VERIFYPEER, 0);
$response = curl&#95;exec($ch);
curl&#95;close($ch);

$response&#95;a = json&#95;decode($response);
 $lat1 = $response&#95;a->results[0]->geometry->location->lat;
 $long1 = $response&#95;a->results[0]->geometry->location->lng;

    Step 2: Finding the latitude and longitude for second place.

     $address2 = "Clock Tower Dehradun";
 $address = str&#95;replace(' ','+',$address2);
 $url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region";
 print("code sample");   $ch = curl&#95;init();
    curl&#95;setopt($ch, CURLOPT&#95;URL, $url);
    curl&#95;setopt($ch, CURLOPT&#95;RETURNTRANSFER, 1);
    curl&#95;setopt($ch, CURLOPT&#95;PROXYPORT, 3128);
    curl&#95;setopt($ch, CURLOPT&#95;SSL&#95;VERIFYHOST, 0);
    curl&#95;setopt($ch, CURLOPT&#95;SSL&#95;VERIFYPEER, 0);
    $response = curl&#95;exec($ch);
    curl&#95;close($ch);
    $response&#95;a = json&#95;decode($response);

    $lat2 = $response&#95;a->results[0]->geometry->location->lat;
    $long2 = $response&#95;a->results[0]->geometry->location->lng;

    Step 3: Find the distance between two places.

    $unit = "K";
$difference = getDistance($lat1,$long1,$lat2,$long2,$unit);

echo "Distance between ".$address1." "."&"." ".$address2." = ".$difference."Km";


 function getDistance($lat1, $long1, $lat2, $long2, $unit) {
$theta = $long1 - $long2;$dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) +  cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta));
      $dist = acos($dist);
      $dist = rad2deg($dist);
      $miles = $dist * 60 * 1.1515;


      if ($unit == "K") {
        return ($miles * 1.609344);
      }  else {
            return $miles;
          }
    }
?>
