calculate latitude and longitude from distance and bearing

Example One function distance ($lat 1, $lng 1, $lat 2, $lng 2, $miles = True){$pi = m_pi/180;$lat 1 *= $PI 80;$LNG 1 *= $PI 80;$lat 2 *= $PI 80;$LNG 2 *= $PI 80;$r = 6372.797;$dlat = $lat 2-$lat 1;$DLNG = $lng 2-$LNG 1;$a = sin ($dlat/2) *sin ($dlat/2) +cos ($lat 1) *cos ($lat 2) *sin ($DLNG/2) *sin ($DLNG/2);$c = 2 * atan2 (sqrt ($a), sqrt (1-$a));$km = $r * $c;Return ($miles? ($KM * 0.621371192): $km);} Example Two /***
