PHP实现返回JSON和XML的类分享

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:
    class Reponse{
        //private $result = array('code'=null,'message'=null,'data'=>null);
       
        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;
        }
       
         public static function xml($code,$message = '',$data = array()){
            if(!is_numeric($code)){
                return false;
            }
            $result = array(
                'code'=>$code,
                'message'=>$message,
                'data'=>$data
            );
            $xml = '';
            $xml .= "n";
            $xml .= "n";
            $xml .= self::xmlEncode($result);
            $xml .= "";
            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 .= "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);

小伙伴们可以直接拿去使用，使用方法在代码的最下方：）
