php simplexml xml application programming

这篇文章主要介绍了php+xml编程之SimpleXML的应用,实例分析了SimpleXML函数操作XML文件的方法,需要的朋友可以参考下

本文实例讲述了php+xml编程之SimpleXML的应用。分享给大家供大家参考。具体如下:

SimpleXML的核心思想:以面向对象的方式来操作xml文件,它会将xml文件的所有元素都转成对象。

xml文档:words.xml

复制代码 代码如下:




 boy
 男孩


 girl
 女孩


 teacher
 老师


 beauty
 美女


simplexml使用实例:

复制代码 代码如下:

echo "

";<br>
$words = simplexml_load_file("words.xml");//返回数组对象,,可以用print_r()或var_dump()查看<br>
var_dump($words);<br>
?>
<p>读取内容:<br>
</p><p><span>复制代码</span> 代码如下:</p><p>
echo "</p><pre class="brush:php;toolbar:false">";<br>
$words = simplexml_load_file("words.xml");//返回数组对象,可以用print_r()或var_dump()查看<br>
//echo $words->word[2];<br>
foreach($words->word as $row){//$row还是一个对象<br>
 print_r($row);<br>
 echo $row->ch."<hr>"; //其实,$row->ch还是一个对象,只不能它能echo出来<br>
}<br>
?><br>
第二段代码输出结果:<br>
<p><span>复制代码</span> 代码如下:</p><p>SimpleXMLElement Object<br>
(<br>
    [en] => boy<br>
    [ch] => 男孩<br>
)<br>
男孩<br>
SimpleXMLElement Object<br>
(<br>
    [en] => girl<br>
    [ch] => 女孩<br>
)<br>
女孩<br>
SimpleXMLElement Object<br>
(<br>
    [en] => teacher<br>
    [ch] => 老师<br>
)<br>
老师</p>
<p>希望本文所述对大家的php+xml程序设计有所帮助。</p>
