Processing XML with SimpleXML

When developing web applications, in order to reduce the I/O overhead of reading and writing databases, some configuration information is often stored in flat files such as XML and json, and then these files are operated through scripting languages ​​such as PHP and javascript.
There are two main ways to operate XML in PHP: one is through DOM, and the other is through SimpleXML. The principle of these two methods of parsing XML is to analyze the entire XML document and provide APIs to access elements in the tree. SimpleXML is a new feature of PHP 5, which aims to easily complete some common XML processing tasks.
Below is a simple example showing how to format a set of XML data through SimpleXML.
