php生成xml和转换[源码]_PHP教程

　　php生成xml就像树一样，逐个添加节点，可以在一个父节点下添加多个子节点， function madexml()

{  

    //获取模板信息  


    $strTempInfo = $this->modelCmsObj->getTemplate(2007);  


    $arrTemp = explode("#",$strTempInfo);  


    array_shift($arrTemp);  


    $arrContents = array();  


    foreach($arrTemp as $k=>$v)  

    {  

        $arrContents[$k]=explode(",",$v);  

    }  

    //解析为xml文件  


    $objDom = new DOMDocument("1.0");  


    header("Content-Type: text/plain");   


    //添加元素和文本节点  


    $root = $objDom->createElement("recommend");  


    $objDom->appendChild($root);  


    foreach($arrContents as $k=>$v)  

    {  

    $item = $objDom->createElement("entry");  


    $root->appendChild($item);  


    $nextitem1 = $objDom->createElement("simgurl");  


    $nextitem2 = $objDom->createElement("imgurl");  


    $nextitem3 = $objDom->createElement("fileurl");  


    $item->appendChild($nextitem1);  


    $item->appendChild($nextitem2);  


    $item->appendChild($nextitem3);  


    $text1 = $objDom->createTextNode($v[0]);  


    $text = $objDom->createTextNode($v[1]);  


    $text2 = $objDom->createTextNode($v[2]);  


    $nextitem2->appendChild($text1);  


    $nextitem3->appendChild($text2);  


    $nextitem1->appendChild($text);  

    }  
 

    echo $objDom->saveXML();  

} 

simplexml_load_string把xml串转化为字符串

$string = //声明xml文档  

1.0?>
