Recently I used the formula for calculating the distance between two points on the earth's surface based on latitude and longitude, and then implemented it using JS. Based on the fact that the earth is a smooth sphere and not a real sphere, there are two ways to expand the sphere. If you are interested, you can use JavaScript to calculate the distance between two points on the earth based on the latitude an

This article describes how php calculates the distance between two coordinates (longitude and latitude). it involves the use of php-related mathematical functions and is of great practical value, for more information about how to use php to calculate the distance between two coordinates (longitude and latitude), see the following example. Share it with you for your reference. The details are as follows:

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. /*** @ Desc calculate the distance * @ param float $ lat
