Php calculates the distance between two coordinates (longitude and latitude). The coordinate longitude is used. Php calculates the distance between two coordinates (longitude and latitude). This article describes how php calculates the distance between two coordinates (longitude and latitude. I would like to share with you how php calculates the distance between two coordinates (longitude and latitude), coordinate longitude
This article describes how php calculates the distance between two coordinates (longitude and latitude. Share it with you for your reference. The details are as follows:
Here, we use php to calculate the distance between two coordinates (longitude, latitude). The Returned result is meter or kilometer.
Function distance ($ lat1, $ lng1, $ lat2, $ lng2, $ miles = true) {$ pi80 = M_PI/180; $ lat1 * = $ pi80; $ lng1 * = $ pi80; $ lat2 X = $ pi80; $ lng2 * = $ pi80; $ r = 6372.797; // mean radius of Earth in km $ dlat = $ lat2-$ lat1; $ dlng = $ lng2-$ lng1; $ a = sin ($ dlat/2) * sin ($ dlat/2) + cos ($ lat1) * cos ($ lat2) * sin ($ dlng/2) * sin ($ dlng/2 ); $ c = 2 * atan2 (sqrt ($ a), sqrt (1-$ a); $ km = $ r * $ c; return ($ miles? ($ Km * 0.621371192): $ km );}
I hope this article will help you with php programming.
