Use PHP to dynamically generate VRML web pages_PHP tutorial

I started studying 3D animation many years ago, and then I learned PHP and found that I could dynamically generate VRML documents through PHP, which is somewhat similar to how Generator dynamically generates Flash.
Due to the broad and profound nature of VRML, we only introduce a simple example here. Various VRML nodes can also be stored in the database. Such a virtual reality web page will be... cool!
The following is the source program. Note: On the server, you must let PHP process the wrl format document, otherwise the result will be no virtual reality. The source program is directly saved as a wrl file. To install the plug-in in the browser, you can download it from my other homepage: http://go.163.com/~sjtucaocao/
