【问题描述】：

提供了这个数组，我正在尝试使用 insert_batch 将它插入到表中。

$arrayOfQuestions 包含多个数组，如下所示：

Array
(
    [0] => Array
        (
            [question_desc] => In human beings, partial pressure of carbon dioxide in the inspired and expired air is respectively
            [option_a] => 0.3 and 40 mm Hg
            [option_b] => 0.3 and 32 mm Hg
            [option_c] => 40 and 46 mm Hg
            [option_d] => 40 and 0.3 mm Hg
            [answer] => B
            [diff_level] => 4
            [solution] => Refer answer.
            [chapter_id] => 54
            [inst_id] => 1
            [subject_id] => 68
            [ref_q_id] => 8540371983
        )

    [1] => Array
        (
            [question_desc] => At high altitude, RBCs of human blood will
            [option_a] => Increase in number
            [option_b] => Decrease in number
            [option_c] => Decrease in size
            [option_d] => Increase in size
            [answer] => A
            [diff_level] => 2
            [solution] => At higher altitudes, due to low pressure of atmospheric oxygen, the body has to carry more oxygen than normal in per volume of blood to supply the body constantly. The increased number of RBC in blood ensures the presence of more haemoglobin and thus more oxygen is carried.
            [chapter_id] => 54
            [inst_id] => 1
            [subject_id] => 68
            [ref_q_id] => 8540371983
        )
)

我得到 return true 我在下面尝试过的代码，但数据没有插入到表中..

$result = $this->db->insert_batch('test_temp_question', $arrayOfQuestions);

【问题讨论】：

insert_batch 返回插入的行数或 FALSE。 $result 的实际值是多少？

【参考方案1】：

成功插入数据的使用条件：

if($result>0)
echo"successfull.";

else
echo"not successfull";
