共分四个文件,分别是创建、增加、删除、修改四个功能,变量都是写死的,改一改用$_POST方式接收就可以用了
//index.php 创建功能
复制代码 代码如下:
$xmlpatch = 'index.xml';
$_id = '1';
$_title = 'title1';
$_content = 'content1';
$_author = 'author1';
$_sendtime = 'time1';
$_htmlpatch = '1.html';
jb51.net$doc = new DOMDocument('1.0', 'utf-8');
$doc -> formatOutput = true;
jb51.net$root = $doc -> createElement('root');//新建节点
jb51.net$index = $doc -> createElement('index');//新建节点
jb51.net$url = $doc -> createAttribute('url');//新建属性
$patch = $doc -> createTextNode($_htmlpatch);//新建TEXT值
$url -> appendChild($patch);//将$patch文本设为$url属性的值
jb51.net$id = $doc -> createAttribute('id');
$newsid = $doc -> createTextNode($_id);
$id -> appendChild($newsid);
jb51.net$title = $doc -> createAttribute('title');
$newstitle = $doc -> createTextNode($_title);
$title -> appendChild($newstitle);
jb51.net$content = $doc -> createTextNode($_content);//节点值
jb51.net$author = $doc -> createAttribute('author');
$newsauthor = $doc -> createTextNode($_author);
$author -> appendChild($newsauthor);
jb51.net$sendtime = $doc -> createAttribute('time');
$newssendtime = $doc -> createTextNode($_sendtime);
$sendtime -> appendChild($newssendtime);
jb51.net$index -> appendChild($id);//将$id设为index节点的属性,以下类同
$index -> appendChild($title);
$index -> appendChild($content);
$index -> appendChild($url);
$index -> appendChild($author);
$index -> appendChild($sendtime);
jb51.net$root -> appendChild($index);//设置index为root字节点
jb51.net$doc -> appendChild($root);//设置root为跟节点
jb51.net$doc -> save($xmlpatch);//保存文件
jb51.netecho $xmlpatch . ' has create success';
