Simplify the task of creating XML documents with the XML_Serializer class, which lets you build nested XML documents from PHP data structures like arrays and objects (and vice versa). I'll show you how to build an XML document tree via the XML_Serializer class from PEAR, how to programmatically create an XML document from an array or an object, how to attach attributes to elements, and how to customize the behavior of the serializer. All this, and much, much more!
And that's about it for this article. Over the last few pages, I showed you how you to build an XML document tree even if your PHP build doesn't support the XML DOM, via the free add-on XML_Serializer class from PEAR. I showed you how to programmatically create an XML document from an array or an object, how to indent XML document nodes, how to attach attributes to elements, and how to customize the behaviour of the serializer. I also showed you to how to reverse-serialize XML documents into PHP arrays or objects for use within a PHP script, together with examples of how type hints could help to make this a more accurate process. Finally, I wrapped things up with a composite example that demonstrated a practical, real-world use for all this code - converting the data in a MySQL database into XML and writing it to a file.
All this is, of course, only the tip of the iceberg; there are an infinite number of possibilities with power like this at your disposal. To find out what else you can do with XML and PHP, I'd encourage you to visit the following links:
