Recent project a feature needs to be based on IP address from Third-party interface to obtain a detailed geographical location, from the Internet to find a lot of examples, the main interface with Sina, Taobao, Tencent. Try Taobao, if it is a small order of magnitude can also, if the order of magnitude to reach the 100,000 level on the slow speed, will lead to system crashes. The following example is Sina,

about 40 functions, which can be used for data query in the future. In our example, I created a table named events with the following fields: id (serial), name (varchar 255), lat (double), and lng (double ). (Don't forget ~~) 4. Calculate the distance between two coordinates To calculate the distance between two coordinates, we need to useEarth_distance (ll_to_earth ($ latlngcube), ll_to_earth ($ latlng_cube ))This function. The earth_distance () function accepts two sets of coordinate values,
