  1. function getDistanceBetweenPointsNew($latitude1, $longitude1, $latitude2, $longitude2) {
  2.     $theta = $longitude1 - $longitude2;
  3.     $miles = (sin(deg2rad($latitude1)) * sin(deg2rad($latitude2))) + (cos(deg2rad($latitude1)) * cos(deg2rad($latitude2)) * cos(deg2rad($theta)));
  4.     $miles = acos($miles);
  5.     $miles = rad2deg($miles);
  6.     $miles = $miles * 60 * 1.1515;
  7.     $feet = $miles * 5280;
  8.     $yards = $feet / 3;
  9.     $kilometers = $miles * 1.609344;
  10.     $meters = $kilometers * 1000;
  11.     return compact('miles','feet','yards','kilometers','meters'); 
  12. }
  13.  
  14. $point1 = array('lat' => 40.770623, 'long' => -73.964367);
  15. $point2 = array('lat' => 40.758224, 'long' => -73.917404);
  16. $distance = getDistanceBetweenPointsNew($point1['lat'], $point1['long'], $point2['lat'], $point2['long']);
  17. foreach ($distance as $unit => $value) {
  18.     echo $unit.': '.number_format($value,4).'<br />';
  19. }
  20.  
  21. The example returns the following:
  22.  
  23. miles: 2.6025
  24. feet: 13,741.4350
  25. yards: 4,580.4783
  26. kilometers: 4.1884
  27. meters: 4,188.3894
