PHP encapsulated HttpClient Class Usage example, package httpclient

The examples in this article describe the HttpClient class for PHP encapsulation. Share to everyone for your reference. The specific analysis is as follows:

This is a PHP encapsulated HttpClient class that enables simple functions such as Get POST Cookie session. Originally done, these two days re-modified a bit.
