PHP implements the function of directly modifying the table content DataGrid_PHP tutorial
Recently I wanted to make something that implements the DataGrid function through PHP, so that the contents of the tables in the database can be directly modified without developing [Add Data Page] and [Edit Page], so I searched online. , there are several similar things, both open source and paid, but they are basically based on MySQL. Since it needs to be connected to Oracle, I personally feel that phpMyDataGrid is relatively easy to get started with in terms of secondary development and page style. This article first introduces the usage based on MySQL, and then briefly introduces the secondary development of Oracle connection (based on sqlrelay).
1. Create test database and tables

2. Introduction to PHP program
phpMyDataGrid is mainly through phpmydatagrid .class.php, dgscripts.js to implement, the total total is less than 100kB, it is a small software. I won’t go into detail about these two documents. Interested students can “pack them away” and go back to read them slowly. It mainly introduces how to use the software, that is, the example datagrid_for_mysql.php. Take a look at the page diagram first:

3. Based on the introduction to Oracle
The main way to read Oracle is to modify the function connected to MySQL in phpmydatagrid.class.php to Oracle. This article is through sqlrelay (please refer to

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
