json_encode 转化数组时，中文不转义出现乱码的解决方法

     一个简单的方法，就是在json_encode($data) ,后面添加一个参数   json_encode($data, JSON_UNESCAPED_UNICODE);

写一个简单的代码

public function appLog($id,$age)
{
    $User = M('User');
    $where['id'] = $id;
    $where['age'] = $age;
    $data = $User->where($where)->select();
    if ($data){
        return $this->api_return('请求成功！',0,$data);
    }else{
        return $this->api_return('请求失败！',-1,'null');
    }
    
}

public function api_return($msg = '', $code = -1, $data = null)
{
    $output = array(
        'message' => $msg,
        'code' => $code,//-1表示错误  0 表示正确返回数据
        'data' => $data
    );
    // 返回JSON数据格式到客户端
    header('Content-Type:application/json; charset=utf-8');
    $output = json_encode($output, JSON_UNESCAPED_UNICODE);
    echo $output;

}

{"message":"请求成功！","code":0,"data":[{"id":"2","name":"sohu","age":"19","email":"[e-mail]","status":"1","sex":"1"}]}
