According To me it’s one of important requirement in many projects related to address. To Calculate distance between two address using latitude and longitude use this method.
function LongLatDistance($Latitude1, $Longitude1, $Latitude2, $Longitude2) {
$theta = $Longitude1 - $Longitude2;
$miles = (sin(deg2rad($Latitude1))*sin(deg2rad($Latitude2)))+(cos(deg2rad($Latitude1))*cos(deg2rad($Latitude2)) * cos(deg2rad($theta)));
$miles = acos($miles);
$miles = rad2deg($miles);
$result['miles'] = $miles * 60 * 1.1515;
$result['feet'] = $result['miles'] * 5280;
$result['yards'] = $result['feet'] / 3;
$result['kilometers'] = $result['miles'] * 1.609344;
$result['meters'] = $result['kilometers'] * 1000;
return $result;
}
$distance = LongLatDistance($lat1='27.3766', $lon1='75.5580', $lat2='26.9124', $lon1='75.7873' );
var_dump($distance);
OUTPUT
array(5) {
["miles"]=>float(35.033155471693)
["feet"]=>float(184975.06089054)
["yards"]=>float(61658.35363018)
["kilometers"]=>float(56.380398559437)
["meters"]=>float(56380.398559437)
}
Enjoy.
