This article mainly introduces the dynamic loading and paging of php and xml. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

This is watching the Pacific Network I saw in the comments that Pacific.com uses jsp as the backend language to generate xml files. Then bind the data to html. I also made one using php. The following is the source file.

The above php, the comments are the data I obtained by connecting to the database. Since I put it up for testing, there is no database connection, so I changed it. I have just started to understand xml, and I still don’t understand many things. Funny...

The above is the entire content of this article. I hope it will be helpful to everyone's study. For more related content, please pay attention to the PHP Chinese website!
