php 站点使用XML文件做配置类

WBOYOriginal: 2016-06-08 17:32:29932browse

要用到,在网站上找了一个,然后自己整理成一个类..

php
/*
*PHP获取和设置XML节点,用于修改和读取站点配置文件
*2008-4-3
*LIQUAN
*eg.get config
*$c = new Configuration(''config.xml'');
*echo( $c->TemplateDirectory." " );
*
* set config
* $c = new Configuration(''config.xml'');
* $c->TemplateDirectory=''test'';
* $c->save();
*/

class Configuration
{
private $configFile;
private $items=array();

//构造函数
function __construct($configFile)
{
   $this->configFile=$configFile;
   $this->parse();
}

//获取属性
function __get($id)
{
    return $this->items[$id];
}

    //设置属性
function __set($key,$value)
{
    $this->$items[$key]=$value;
}

//解析XML文件保存到数组
function parse()
{
    $doc=new DOMDocument();
    $doc->load($this->configFile);
    $cn=$doc->getElementsByTagName(''config'');
    $nodes=$cn->item(0)->getElementsByTagName(''*'');
    foreach($nodes as $node)
    {
          $this->items[$node->nodeName]=$node->nodeValue;
    }
}

//保存XML文件
    function save()
    {
    $doc=new DOMDocument();
       $doc->formatOutput=true;

    $r=$doc->createElement(''config'');
       $doc->appendChild($r);

    foreach($this->items as $k=>$v)
    {
         $keyName=$doc->createElement($k);
         $keyName->appendChild($doc->createTextNode($v));
   $r->appendChild($keyName);
    }
    copy($this->configFile,$this->configFile.".bak");

    $doc->save($this->configFile);
    }

}

?>
