PHP WeChat scans the code to pay attention to the public account and authorize login. Although PHP WeChat scanning code login may seem simple, actual development may take a lot of time.

Overview of source code functions:
Step 1: Get a ticket that focuses on the QR code, and pass the primary key id of the QR code qrcode table.

Step 2: The WeChat server receives data, including user login information.

Step 3: Check every 2 seconds whether the user has paid attention to the Weixin Official Accounts, then use WeChat's openid and access_token to obtain user information and save the information in the table.
