Hi folks,
I found this kind of formulae which should calculate the distance between two points on earth:
tc1=mod(atan2(sin(lon1-lon2)*cos(lat2),
cos(lat1)*sin(lat2)-sin(lat1)*cos(lat2)*cos(lon1-lon2)), 2*pi)
This is not PHP code, but now I would need the same formulae in PHP. But I can't find what that
mod(x, x) -function does. Any idea is there corresponding function in PHP?
Cheers,
- Ville
