本文实例讲述了PHP读取XML文件的方法，分享给大家供大家参考，具体如下： 使用DOMDocument对象读取xml 创建一个DOMDocument对象 $doc = new DOMDocument(); 载入xml文件 $doc->load("book.xml"); 获取标签对象 $books = $doc->getElementsByTagName("book"); 获取标签的子对象 $titles = $book->getElementsByTagName("title"); 获取标签的值或属性 $title = $titles->item(0)->nodeValue; 实例1，读取配置文件 config.xml <?xml version="1.0" encoding="UTF-8"?> <mysql> <host>127.0.0.1</host> <username>root</username> <password></password> <database>test</database> </mysql> config.php <?php header("Content-type:text/html;charset=utf8"); $doc = new DOMDocument(); //创建DOMDocument对象 $doc->load("config.xml"); //打开config.xml $mysql = $doc->getElementsByTagName("mysql"); //获取mysql标签对象 $host = $mysql->item(0)->getElementsByTagName("host"); $config["host"] = $host->item(0)->nodeValue; $username = $mysql->item(0)->getElementsByTagName("username"); $config["username"] = $username->item(0)->nodeValue; $password = $mysql->item(0)->getElementsByTagName("password"); $config["password"] = $password->item(0)->nodeValue; $database = $mysql->item(0)->getElementsByTagName("database"); $config["database"] = $database->item(0)->nodeValue; var_dump($config); 实例2，获取图书列表 book.xml <?xml version="1.0" encoding="UTF-8"?> <bookstore> <book> <title>PHP和MySQL开发</title> <author>谭浩强</author> </book> <book> <titile>xml从入门到精通</titile> <author>郑智化</author> </book> </bookstore> load.php <?php header("Content-type:text/html;charset=utf8"); $doc = new DOMDocument(); //创建DOMDocument对象 $doc->load("book.xml"); //打开book.xml $books = $doc->getElementsByTagName("book"); //获取book标签对象 foreach ($books as $book){ //遍历对象 $titles = $book->getElementsByTagName("title"); //获取book标签下的title标签 $title = $titles->item(0)->nodeValue; //获取标签的值 $authors = $book->getElementsByTagName("author");//获取book标签下的author标签 $author = $authors->item(0)->nodeValue; //获取标签的值 $item["title"] = $title; $item["author"] = $author; $bookinfo[] = $item; } var_dump($bookinfo); 使用simplexml方法读取xml 实例1，读取配置文件 config.php <?php header("Content-type:text/html;charset=utf8"); $mysql = simplexml_load_file("config.xml"); $config['host'] = $mysql->host; $config['username'] = $mysql->username; $config['password'] = $mysql->password; $config['databse'] = $mysql->database; var_dump($config);。 实例2，获取图书列表 load.php <?php header("Content-type:text/html;charset=utf8"); $books = simplexml_load_file("book.xml"); foreach($books as $book){ $item["title"] = $book->title; $item["author"] = $book->author; $booklist[] = $item; } var_dump($booklist); （编辑：大连站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
