How to add xml document content through php, add xml document with php

The example in this article describes how to add xml document content through php. Share it with everyone for your reference. The specific analysis is as follows:

The addition of XML document content described here continues from the previous article "DOM Basics and PHP Reading XML Content Operation Method", the code is as follows:

Copy code The code is as follows:

//1. Create a DOMDocument object. This object represents the xml file
$xmldoc = new DOMDocument();
//2. Load the xml file (specify which xml file to parse, then the dom tree node will be loaded into the memory)
$xmldoc->load("class.xml");
//3. Add a student information
//(1) Take out the desired node
$root = $xmldoc->getElementsByTagName("class")->item(0);//Return DOMElement object type
var_dump($root);
//(2)Create student node student
$stu_node = $xmldoc->createElement("student");//Return DOMElement object type
$stu_node->setAttribute("id","Big Beauty");//Add attributes to the created node, if necessary
//(3) Create name, gender, age and other nodes name, sex and age
$stu_node_name = $xmldoc->createElement("name");
$stu_node_name->nodeValue = "Da Qiao";
$stu_node_sex = $xmldoc->createElement("sex");
$stu_node_sex->nodeValue = "Female";
$stu_node_age = $xmldoc->createElement("age");
$stu_node_age->nodeValue = "25";
//(4) Mount the three nodes such as name, sex, and age to the student node
$stu_node->appendchild($stu_node_name);
$stu_node->appendchild($stu_node_sex);
$stu_node->appendchild($stu_node_age);
//(5)Mount the student node to the root node
$root->appendchild($stu_node);
//4. Save to xml document
//$xmldoc->save("class.xml");//Save it to the original xml document, which is equivalent to adding it later; if it is an xml document that does not exist, a new xml document will be created with the content of the original xml content + newly added content.
