Hello Everyone, today I am here to guide you "How to calcuate distance between 2 place with the help of zip code in Php".

$point and $point are two places, you can pass these values into total_distance() function
$radius is earth radius in miles
$distance return the calculated distance between 2 points.

The below code helps you to find the distance between 2 place.

function total_distance($point1, $point2)
{
    $radius      = 3958;      // radius
    $deg_per_radius = 57.29578;  // degrees

    $distance = ($radius * pi() * sqrt(
                ($point1['lat'] - $point2['lat'])
                * ($point1['lat'] - $point2['lat'])
                + cos($point1['lat'] / $deg_per_rad)  
                * cos($point2['lat'] / $deg_per_rad)  
                * ($point1['long'] - $point2['long'])
                * ($point1['long'] - $point2['long'])
        ) / 180);

    return $distance;  // Returned using the units used for $radius.
}
