It's time to summarize the simple PHP system production skills learned some time ago.
Some time ago, I mainly talked about how to use PHP to read and query data in MySQL, and explained to you how to make a PHP multi-condition combination query. Of course, it is very important for everyone to understand how to configure PHP+APACHE+MySQL.
If you have any questions in the PHP simple information system data query module, you are welcome to leave a message.
Here, I have prepared a file for everyone, which collects the previous codes for your reference. Click to download.
