PHP Desktop Center (1) Creating a Database_PHP Tutorial
This is my first time writing an article. I don’t know if it can be published. . I wrote the program so that everyone can refer to it. If there is any expert who can modify a better program,
please don’t forget to tell me. :P
The demo page of the source program is at elong.oso.com.cn/desk/
The first step is to create the database:
We will use the OSO database as a column to explain.
Log in to the database first. Then click on your database name on the left.
Enter the following command where you enter the command.
CREATE TABLE jpg (
id int(8) NOT NULL auto_increment,
url char(255) NOT NULL,
mess char(100) NOT NULL,
fromx char(50) NOT NULL,

These commands mean to create four tables to store data. This represents the four categories of images. If you want to add classes, you can add more tables and change the source program.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
