PHP实现对xml进行简单的增删改查(CRUD)操作示例

<?xml version="1.0" encoding="UTF-8"?>
<setting>
  <preferTime>55.8</preferTime>
  <playerValue>56</playerValue>
  <reduceValue>40</reduceValue>
  <reduceTime>339</reduceTime>
</setting>

<?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!");
  }
}
