假如有以下xml文件：

<?xml version="1.0" encoding="UTF-8"?

>

<setting>

    <preferTime>55.8</preferTime>

    

    <playerValue>56</playerValue> 

    

    <reduceValue>40</reduceValue> 

    

    <reduceTime>339</reduceTime> 

</setting>

怎样使用php对它进行CRUD？事实上像这样的简单的xml文件使用SimpleXMl再好只是了。你能够像这样来操作它：

<?php

//获取数据 get the config data

if(isset($_GET["type"])){

	if($_GET["type"]=="get"){

	   $xml=simplexml_load_file("../config.xml");

       $config=array("preferTime"=>$xml->preferTime."",

       	                 "playerValue"=>$xml->playerValue."",

       	                 "reduceValue"=>$xml->reduceValue."",

       	                 "reduceTime"=>$xml->reduceTime."");

	   echo json_encode($config);

	}

//更新数据 update the config data

	if($_GET["type"]=="update"){

	   $xml=simplexml_load_file("../config.xml");

    	$xml->preferTime=$_GET["data"]["preferTime"];

    	$xml->playerValue=$_GET["data"]["playerValue"];

    	$xml->reduceValue=$_GET["data"]["reduceValue"];

    	$xml->reduceTime=$_GET["data"]["reduceTime"];

	    $xml->asXML("../config.xml");

	   echo json_encode("save success!");

	}

}
