由 dawei 本文章给来大家讲一下关于PHP下simplexml使用方法,希望通过此文章能提升大家对simplexml操作xml文档的理解,有需要了解的朋友可参考.
PHP XML处理XML代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Edited with XML Spy v2007 (http://www.Cuoxin.com) -->

<food id="1">
<name>Belgian Waffles</name>

php解决xml代码,代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>使用simpleXML处理XML</title>
</head>
<body>
<table border="1" cellpadding="0" cellspacing="0" width="700">
</tbody>
<tr bgcolor="green">
<th width="5%"> </th>
<th width="20%">name</th>
<th width="10%">price</th>
<th width="55%">description</th>
<th width="10%">calories</th>
</tr>
<?php
// 使用simpleXML处理XML
$xml = simplexml_load_file('./simple.xml');
//var_dump($xml);
//echo $xml->getName();
//var_dump($xml->children());
$record = '';
foreach ($xml->children() as $child)
{
$record .= '<tr><td>'. $child->attributes(). '</td>';
foreach ($child->children() as $item)
{
//var_dump($child);
$record .= '<td>'. $item .'</td>';
}
$record .= '</tr>';
}//开源代码Cuoxin.com
echo $record;
?>
</tbody>
</table>
</body>
</html>
将XML转换为数组结构,代码如下:
private function change_simple_xml_to_array($obj){
$i = 0;
//从根节点下的二层子节点开始遍历
foreach($obj->children() as $value){
//如果发生同级、同标签名的情况，则加一维数组；
if(isset($last_name) && $value->getName()==$last_name){
//出现同名发现第二个，则推入第二维数组；
if($i==1) $arr[$last_name]=array($arr[$last_name]);
//遍历子节点；
array_push($arr[$last_name],$this->change_simple_xml_to_array($value));
}else{
$last_name = $value->getName();
if(count($value->children())==0) $arr[$last_name] = $value."";
else $arr[$last_name] = $this->change_simple_xml_to_array($value);
}
$i++;
}
return $arr;
}

//转换后的数组————
