The previous article introduced you to "Do you know what XML Expat is? How does he define it? 》, this article continues to introduce to you. Regarding the understanding of XML SimpleXML, I believe you will definitely make new discoveries and gains. Come on, let’s explore together!
SimpleXML is a new feature in PHP 5.
- The SimpleXML extension provides a simple way to get the name and text of an XML element.
- Compared to DOM or Expat parsers, SimpleXML can read text data from XML elements in just a few lines of code.
- SimpleXML can convert XML documents (or XML strings) into objects, for example:
- Properties are accessed using an associative array, where the index corresponds to the property name.
- The text inside the element is converted to a string. If an element has multiple text nodes, they are arranged in the order in which they are found.
- SimpleXML is very fast to use when performing basic tasks like:
Reading/extracting data from XML files/strings
Editing text nodes or attributesHowever, when dealing with advanced XML, such as namespaces, it is best to use the Expat parser or XML DOM.Installation:
Starting with PHP 5, SimpleXML functions are an integral part of PHP core. No installation is required to use these functions.
PHP SimpleXML Example: Suppose we have the following XML file, "note.xml":1 2 3 4 5 6 7 |
|
1 2 3 4 |
|
Output the data of each element in the XML file:
1 2 3 4 5 6 7 8 |
|
