Hello! In this post, you will learn how to calculate distance between two places using google map API in php.
Here you will calculate by air distance between two countries.
See below ..how to do it.
results[0]->geometry->location->lat;
$longitudeFrom = $outputFrom->results[0]->geometry->location->lng;
$latitudeTo = $outputTo->results[0]->geometry->location->lat;
$longitudeTo = $outputTo->results[0]->geometry->location->lng;
//Calculate distance from latitude and longitude
$theta = $longitudeFrom - $longitudeTo;
$dist = sin(deg2rad($latitudeFrom)) * sin(deg2rad($latitudeTo)) + cos(deg2rad($latitudeFrom)) * cos(deg2rad($latitudeTo)) * cos(deg2rad($theta));
$dist = acos($dist);
$dist = rad2deg($dist);
$miles = $dist * 60 * 1.151;
$unit = strtoupper($unit);
if ($unit == "K") {
return ($miles * 1.609344).' km';
} else if ($unit == "N") {
return ($miles * 0.8684).' nm';
} else {
return $miles.' mi';
}
}
if(isset($_REQUEST['cal']))
{
$addressFrom = $_POST['addressfrom'];
$addressTo =$_POST['addressto'];
$distance = getDistance($addressFrom, $addressTo, "K");
}
?>
