本文实例讲述了通过php添加xml文档内容的方法。分享给大家供大家参考。具体分析如下:
这里讲述的添加xml文档内容,从上一篇《DOM基础及php读取xml内容操作的方法》继续,代码如下:
$xmldoc = new DOMDocument();
//2、加载xml文件(指定要解析哪个xml文件,此时dom树节点就会加载到内存中)
$xmldoc->load("class.xml");
//3、添加一条学生信息
//(1)取出要节点
$root = $xmldoc->getElementsByTagName("class")->item(0);//返回DOMElement对象类型
var_dump($root);
//(2)创建学生节点 student
$stu_node = $xmldoc->createElement("student");//返回DOMElement对象类型
$stu_node->setAttribute("id","大美女");//给创建的节点添加属性,如果有需要的话
//(3)创建名字、性别、年龄等节点 name、sex和age
$stu_node_name = $xmldoc->createElement("name");
$stu_node_name->nodeValue = "大乔";
$stu_node_sex = $xmldoc->createElement("sex");
$stu_node_sex->nodeValue = "女";
$stu_node_age = $xmldoc->createElement("age");
$stu_node_age->nodeValue = "25";
//(4)将name、sex、age等三个节点挂载到student节点上
$stu_node->appendchild($stu_node_name);
$stu_node->appendchild($stu_node_sex);
$stu_node->appendchild($stu_node_age);
//(5)把student节点挂载到根节点上
$root->appendchild($stu_node);
//4、保存到 xml 文档中
//$xmldoc->save("class.xml");//保存到原xml文档中,相当于在后面添加;如果是一个不存在的xml文档,则会新建一个xml文档,内容为原xml内容+新添加的内容。
?>
希望本文所述对大家的php操作XML程序设计有所帮助。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
