【www.gdgbn.com--php常用代码】
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教程 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";
$_htmlpatch = "1.html";
111cn.net$doc = new domdocument("1.0", "utf-8");
$doc -> formatoutput = true;
111cn.net$root = $doc -> createelement("root");//新建节点
111cn.net$index = $doc -> createelement("index");//新建节点
111cn.net$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
111cn.net$id = $doc -> createattribute("id");
$newsid = $doc -> createtextnode($_id);
$id -> appendchild($newsid);
111cn.net$title = $doc -> createattribute("title");
$newstitle = $doc -> createtextnode($_title);
$title -> appendchild($newstitle);
111cn.net$content = $doc -> createtextnode($_content);//节点值
111cn.net$author = $doc -> createattribute("author");
$newsauthor = $doc -> createtextnode($_author);
$author -> appendchild($newsauthor);
111cn.net$sendtime = $doc -> createattribute("time");
$newssendtime = $doc -> createtextnode($_sendtime);
$sendtime -> appendchild($newssendtime);
111cn.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);
111cn.net$root -> appendchild($index);//设置index为root字节点
111cn.net$doc -> appendchild($root);//设置root为跟节点
111cn.net$doc -> save($xmlpatch);//保存文件
111cn.netecho $xmlpatch . " has create success";
111cn.net?>
111cn.net
111cn.net
//add.php 增加功能(跟index.php文件差不多，主要就是加个load载入跟 $root = $doc -> documentelement获得跟节点
复制代码 代码如下:
$xmlpatch = "index.xml";
$_id = "2";
$_title = "title2";
$_content = "content2";
$_author = "author2";
$_sendtime = "time2";
$_htmlpatch = "2.html";
111cn.net$doc = new domdocument();
$doc -> formatoutput = true;
if($doc -> load($xmlpatch)) {
$root = $doc -> documentelement;//获得根节点(root)
$index = $doc -> createelement("index");
111cn.net$url = $doc -> createattribute("url");
$patch = $doc -> createtextnode($_htmlpatch);
$url -> appendchild($patch);
111cn.net$id = $doc -> createattribute("id");
$newsid = $doc -> createtextnode($_id);
$id -> appendchild($newsid);
111cn.net$title = $doc -> createattribute("title");
$newstitle = $doc -> createtextnode($_title);
$title -> appendchild($newstitle);
111cn.net$content = $doc -> createtextnode($_content);
111cn.net$author = $doc -> createattribute("author");
$newsauthor = $doc -> createtextnode($_author);
$author -> appendchild($newsauthor);
111cn.net$sendtime = $doc -> createattribute("time");
$newssendtime = $doc -> createtextnode($_sendtime);
$sendtime -> appendchild($newssendtime);
111cn.net$index -> appendchild($id);
$index -> appendchild($title);
$index -> appendchild($content);
$index -> appendchild($url);
$index -> appendchild($author);
$index -> appendchild($sendtime);
111cn.net$root -> appendchild($index);
111cn.net$doc -> save($xmlpatch);
111cn.netecho $_id . " has been added in " . $xmlpatch;
111cn.net} else {
echo "xml file loaded error!";
}
?>
111cn.net
//edit.php 修改功能(这里只修改title属性值 跟节点值)
复制代码 代码如下:
$xmlpatch = "index.xml";
$_id = "2";
$_title = "has been changed";
$_content = "has been changed";
111cn.net$doc = new domdocument();
$doc -> formatoutput = true;
111cn.netif($doc -> load($xmlpatch)) {
$root = $doc -> documentelement;
$elm = $root -> getelementsbytagname("index");
$checkexist = 0;
foreach ($elm as $new) {
if($new -> getattribute("id") == $_id) {
$new -> setattribute("title", $_title);
$new -> nodevalue = $_content;//修改节点值，真是太意外了，没想到跟js一样直接能赋值...
//$new -> removechild($new -> nodevalue);
$checkexist = 1;
}
}
if($checkexist == 0) {
echo $_id . " is not found in " . $xmlpatch;
} else {
$doc -> save($xmlpatch);
echo $_id . " has been changed";
}
} else {
echo "xml file loaded error!";
}
111cn.net?>

//del.php 删除功能
复制代码 代码如下:
$xmlpatch = "index.xml";
$_id = "2";
111cn.net$doc = new domdocument();
$doc -> formatoutput = true;
if($doc -> load($xmlpatch)) {
$root = $doc -> documentelement;
$elm = $root -> getelementsbytagname("index");
foreach ($elm as $new) {
if($new -> getattribute("id") == $_id) {
if($root -> removechild($new)) {
echo $_id . " has been deleted";
} else {
echo $_id . " delete failed";
}
}
}
$doc -> save($xmlpatch);
} else {
echo "xml file loaded error!";
