Php_app (communication) interface-interface three elements ____php

Three key elements of app interface implementation:

1. Interface address, such as http://www.server.com/data.php

The interface address is equivalent to the request address in the B/s architecture, and the principle is similar;

2. Interface file: data.php

The interface file is used to process the logic and return the processed data;

3, interface data;

The data returned by the pretext file;

The most commonly used data types are XML and JSON;

JSON is less readable than XML, but it generates faster and travels faster than XML;;;
