## php 封装接口类返回json/xml数据 ##

response.php

<?php
    
    class Response { 
        /* *按json格式返回数据 *@param int $code 状态码 *@param string $message 提示信息 *@param arrya $data 数据 *return string */
         public static function getJson($code ,$message = '',$data = array()) { 
    
            if(!is_numeric($code)) {
                return '';
            }
    
            $arr = array(
                'code' => $code,
                'message' => $message,
                'data' => $data
            );
    
            echo json_encode($arr);
            exit;
    
         }
         /* *按xml格式返回数据 *@param int $code 状态码 *@param string $message 提示信息 *@param arrya $data 数据 *return string */
         public static function getXml($code,$message = '',$data = array()) { 
    
            if(!is_numeric($code)) {
                return '';
            }
    
            header("Content-Type:text/xml");
    
            $result  = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n";
            $result .= "<root>\n";
            $result .= "<code>" . $code . "</code>\n";
            $result .= "<message>" . $message . "</message>\n";
            $result .= "<data>\n" . self::getData($data) . "</data>\n";
            $result .= "</root>";
    
            echo $result;
            exit;
         }
         /* *将$data转换为xml字符串 *@param arrya $data 数据 *return string */
         private static function getData($data = array()) { 
    
            $str = '';
    
            foreach ($data as $key => $value) {
    
                $s = '';
                if(is_numeric($key)) {
                    $s = " id='" . $key . "'";
                    $key = "item";
    
                }
    
                $str .= "<" . $key . $s .">";
                $str .= is_array($value) ? "\n" . self::getData($value) : $value; 
                $str .= "</" .$key . ">\n";
            }
            return $str;
         }
    }

在test.php中使用

<?php
    
    require_once('./response.php');
    $arr = array(
        'id'=>'1',
        'name'=>'2',
        'da' => array(
            'a' =>1,
            'b' =>2
            ),
        'ca' =>array(12,12)
        );
    //Response::getjson(12,'1',$arr);
    Response::getXml(12,'12',$arr);
