我是靠谱客的博主闪闪大门，最近开发中收集的这篇文章主要介绍PHP实现返回JSON和XML的类分享，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

代码很简洁，功能也很简单实用，这里就不多废话了，直接奉上代码：

复制代码代码如下:

<?php

    class Reponse{

        //private $result = array('code'=null,'message'=null,'data'=>null);

        /**

         * @desc 返回JSON格式

         * @param int $code 

         * @param string $message 

         * @param array  $data

         * return string

         */

        public static function json($code,$message = null,$data = array()){

            if(!is_numeric($code)){

                return false;

            }

            $result = array(

                'code'=>$code,

                'message'=>$message,

                'data'=>$data

            );

            return json_encode($result);

            exit;

        }

        /**

         * @desc 返回xml格式数据

         * @parma int $code 状态码

         * @param string $message 提示

         * @param array $data 数据

         * return string 

         */

         public static function xml($code,$message = '',$data = array()){

            if(!is_numeric($code)){

                return false;

            }

            $result = array(

                'code'=>$code,

                'message'=>$message,

                'data'=>$data

            );

            $xml = '';

            $xml .= "<?xml version='1.0' encoding='UTF-8'?>\n";

            $xml .= "<root>\n";

            $xml .= self::xmlEncode($result);

            $xml .= "</root>";

            header("Content-Type:text/xml");

            echo $xml;

         }

         public static function xmlEncode($result){

            $xml = $attr ='';

            foreach($result as $key=>$val){

                if(is_numeric($key)){

                    $attr = "id='{$key}'";

                    $key = "item{$key}";

                }

                $xml .= "<{$key} {$attr}>";

                $xml .= is_array($val) ? self::xmlEncode($val) : $val;

                $xml .= "</{$key}>\n";

            }

            return $xml;

         }

    }

    $data = array(

        'id'=>1,

        'age'=>20,

        'username'=>'tim',

        'others'=>array(1,2,3),

    );

    Reponse::xml(200,'success',$data);

    Reponse::json(200,'success',$data);
