The following is my PHP code used to calculate the distance between two GPS longitude and latitude coordinates. If you need it, you can use it directly. The code is as follows:Copy code /*** Calculate the distance between two coordinates (meters)* @ Param float $ fP1Lat start point (latitude)* @ Param float $ fP1Lon start point (longitude)* @ Param float $ fP
