PHP XML3 operation: Create an XML document using a DOM object

But the author himself in writing code is also encountered a problem, the file format can only be UTF-8, but when creating a DOM object, there is a parameter that can select encoding. If you know what is going on, contact me. In "XML entry 6: loading XML documents with DOM objects", we have learned how to use the php dom extension component to load XML documents and print them on the screen.
