This article mainly introduces how PHP calculates the distance based on the longitude and latitude between two points. The code is very simple, but it is very practical. if you need it, you can refer to this as a good example and paste the code directly, first, you must know the latitude and longitude values. /***

After graduation for several years, even the trigonometric function forgot to know the latitude and longitude of the two points of AC or BC. how can I use php to find the angle of α or beta? thank you! After graduation for several years, I forgot my trigonometric function. We know that the latitude and longitude of t

This example describes the PHP method for calculating the maximum minimum latitude and longitude of 4 corners in the current coordinates of 3 km. Share to everyone for your reference, as follows: $LNG, $lat latitude and longitude $half = 6371; $distance = 3; 3 km $DLNG = 2 * ASIN (SIN ($distance/(2 * $hal

This article describes how to calculate the distance between two points based on the latitude and longitude of python. For more information, see The code is as follows: /*** Calculate the distance between two points* @ Param _ lat1-start latitude* @ Param _ lon1-start longitude* @ Param _ lat2-end
