php构造json多维数组的方法

php构造json多维数组其实很简单

下面列举了将mysqli的查询结果数组序列化为json的php代码如下

        $res['result'] = "ok";
        $res['msg'] = 'login';
        $res['fileinfo'] = array();

        while($stmt->fetch()){ 
                $fileinfo['fileid'] = $fileid;
                $fileinfo['name'] = $name;
                $fileinfo['fujianname'] = $fujianname;
                array_push($res['fileinfo'], $fileinfo);
        }

        echo json_encode($res);

输出的字符串如下：

{"result":"ok","msg":"login","fileinfo":[{"fileid":113,"name":"jishumingcheng","fujianname":"test.txt_test_20161005214223"},{"fileid":114,"name":"wodejishu","fujianname":"test.txt_test2_20161005230610"}]}
