How to write a simple Online GPS tracker?

Question

PHP

I wanted to know how to implement a simple GPS tracker that can track the location and mark the path on the map, and how to make it possible to determine the distance to a specific object?
As I understand it, using html5, you can determine the location, how to mark it on the map?
Then I'm going to update the plugin and write the coordinates of the points to a file or draw on the map right away and determine the distance to the desired object.
