Php-androidAPP allows you to log on to WeChat and establish connection and communication with the PHP Server (with a reward of 10 C coins)

Hello everyone, I want to build a system for communications between an APP and a PHP Server. the APP needs to connect and communicate with the PHP server through logon, saves the information and data of users logging on to the APP to the PHP server so that the information can be obtained from the next APP login. ** My idea is as follows **: The APP login process does not need to communicate with my PHP Server. Once the login is successful, a connection is established with the PHP server to establish a connection, we need to use a user name and password defined by ourselves to establish a connection. after the connection is successful, send the user ID to the server to query the relevant information. _ I feel a lot of questions... the server phpandroidapp

Hello everyone, I want to build a system for communications between an APP and a PHP Server. the APP needs to connect and communicate with the PHP server through logon, saves the information and data of users logging on to the APP to the PHP server so that the information can be obtained from the next APP login.

My thoughts are as follows::
The APP does not need to communicate with my PHP Server during login. Once the login is successful
The PHP server requires a user name and password defined by us to establish a connection.
To establish a connection. after the connection is successful, send the user ID to the server to query the relevant information.
I feel that there are many problems and deficiencies, because I have never done it. I hope you can give me some advice or give me some links to see examples.
Thank you.
