PHP DOMDocument实现XML读写操作

domdocument

在php中操作xml文档我们可以直接调用DOMDocument类或使用simplexml_load_string类来操作,这些都不需要加载算是内置函数了,我们直接使用.

PHP脚本读取XML最原始,最笨的方法,代码如下:

$doc = new DOMDocument();  
$doc->load(&#39;test.xml&#39;);  
$rows = $doc->getElementsByTagName("ds");  
$d = array();  
$i = 0;  
foreach($rows as $row)  
{  
   $web     = $row->getElementsByTagName(&#39;web&#39;);  
   $webUrl  = $row->getElementsByTagName(&#39;webUrl&#39;);  
   $d[$i][&#39;web&#39;]    = $web->item(0)->nodeValue;  
   $d[$i][&#39;webUrl&#39;] = $webUrl->item(0)->nodeValue;  
   $i++;  
}  
print_R($d);

简单,容易,速度快,代码如下:

$xmlData = file_get_contents(&#39;test.xml&#39;);  
$xml = simplexml_load_string($xmlData);  
$xmlArr = objectToArray($xml);

objectToArray函数代码如下:

function objectToArray($object)  
{    
   if(!$object) return &#39;&#39;;  
   $result = array();    
   $object = is_object($object) ? get_object_vars($object) : $object;    
   foreach ($object as $key => $val) {    
       $val = (is_object($val) || is_array($val)) ? objectToArray($val) : $val;    
       $result[$key] = $val;    
   }    
   return $result;    
}

上面讲到了读取xml,下面再介绍写xml实例,代码如下:

$arr = array(  
    array(&#39;id&#39;=>1,&#39;web&#39;=>&#39;好脚本&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com&#39;),  
    array(&#39;id&#39;=>2,&#39;web&#39;=>&#39;PHP脚本&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com/&#39;),  
    array(&#39;id&#39;=>3,&#39;web&#39;=>&#39;JavaScript脚本&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com/&#39;),  
    array(&#39;id&#39;=>4,&#39;web&#39;=>&#39;js脚本&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com/&#39;),  
    array(&#39;id&#39;=>5,&#39;web&#39;=>&#39;PHP脚本示例&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com/&#39;),  
    array(&#39;id&#39;=>5,&#39;web&#39;=>&#39;JavaScript脚本示例&#39;,&#39;webUrl&#39;=>&#39;http://www.phprm.com/&#39;)  
);  
/*使用dom生成xml,注意生成的xml中会没有空格。*/ 
$dom=new DOMDocument(&#39;1.0&#39;,&#39;utf-8&#39;);  
$path= "logs/test.xml";  
$data=$dom->createElement(&#39;data&#39;);  
$dom->appendChild($data);  
foreach($arr as $v)  
{  
    $ds = $dom->createElement(&#39;ds&#39;);  
    $id = $dom->createAttribute(&#39;id&#39;);   
    $id->nodeValue = $v[&#39;id&#39;];  
    $ds->setAttributeNode($id);  
    $data->appendChild($ds);  
    foreach($v as $kk=>$vv)  
    {  
       ${$kk} = $dom->createElement($kk);   
       $value= $dom->createTextNode($vv);  
       ${$kk}->appendChild($value);  
       $ds->appendChild(${$kk});  
    }  
}  
$dom->saveXML();  
$dom->save($path);
