Calculating the distance between two points using latitude and…

1. function distance($lat1, $lon1, $lat2, $lon2) {
2. $pi80 = M_PI / 180;
3. $lat1 *= $pi80;
4. $lon1 *= $pi80;
5. $lat2 *= $pi80;
6. $lon2 *= $pi80;
7. $r = 6372.797; // mean radius of Earth in km.
8. $dlat = $lat2 – $lat1;

How to calculate distance in meters using MySQL?
