我需要插入多个数组。我得到错误：mysql\\u real\\u escape\\u string（）期望参数1是字符串，数组给定

我的示例代码：

 $array_info is 
    Array
(
[0] => Array
    (
        [0] => a
        [1] => b
        [2] => c
    )

[1] => Array
    (
        [0] => d
        [1] => e
        [2] => f
    )

)

 $data = array(
        \'blog_id\' => NULL,
        \'post_id\' => $id,
        \'ing\' => $array_info
        );
        $insert = $wpdb->insert($table_name, $data);
