# When lon is Longitude and lat is latitude, do not make a mistake. Functiondistance ($ lon1, $ lat1, $ lon2, $ lat2 ){ Return (2 * ATAN2 (SQRT (SIN ($ lat1-$ lat2) * PI ()/180/2) * SIN ($ lat1-$ lat2) * PI ()/180/2) + COS ($ lat2 * PI ()/180) * COS ($ lat1 * PI ()/180) * SIN ($ lon1-$ lon2) * PI ()/180/2) * SIN ($ lon1-$ lon2) * PI ()/180/2 )), SQRT (1-SIN ($ lat1-$ lat2) * PI ()/180/2) * SIN ($ lat1-$ lat2) * PI ()/180/2) + COS ($ lat2 * PI ()/180) * COS ($ lat1 * PI ()/180) * SIN ($ lon1-$ lon2) * PI ()/180/2) * SIN ($ lon1-$ lon2) * PI ()/180/2) * 6378140; }

Call method:

Echo distance (39.91917, 116.3896, 39.91726, 116.3940 );

1	Echodistance (39.91917, 116.3896, 39.91726, 116.3940 );
