PHP reads the longitude and latitude of Google Maps

Referring to the online part of the data, they rewrote a convenient access to latitude and longitude information of the class Geo, where latitude and longtitude respectively are latitude and longitude. One of the most important constructors is the incoming place name, which is obtained by WebRequest from the Google Map, and can be easily invoked in a project that contains geographic information, GEO g = new Geo ("Beijing Normal University"), and then G. Latitude and G.longtitude are the latitude and longitude of Beijing Normal University, which are 39.9614580, 116.3692820 respectively. The implementation of GEO is as follows:
