Question

我有multidimentions数组hrefs：

Array
(

[1] => Array
    (
        [0] => http://213b572-ba681bf9cc9e
        [1] => http://f057-4139-ac40-bc4449722ffc
        [2] => http://b-c151-4ba1-b7b7-842771c36d6b
        [3] => http://5a77fb-8fce-4793-868f-c9fd73524037
    )

[2] => Array
    (
        [0] => http://8-d832-4b34-a55b-da04ad8cdd09
        [1] => http://b38-6a60-4233-b207-f40fae2ef431
        [2] => http://3-f31c-49c4-87ee-fcada05a105f
        [3] => http://07514-e438-45e2-906e-b440cbcbf8dc
    )

......

[76] => Array
    (
        [0] => http://8-d832-4b34-a55b-da04ad8cdd09
        [1] => http://b38-6a60-4233-b207-f40fae2ef431
        [2] => http://3-f31c-49c4-87ee-fcada05a105f
        [3] => http://07514-e438-45e2-906e-b440cbcbf8dc
    )

当我将数组hrefs插入数据库

时

foreach ($hrefs as $id_page =>  $href) {
    foreach ($href as $value) {
        mysqli_query($con, "INSERT INTO urls(`id`, `id_page`, `url`)
                    VALUES ('', '$id_page', '$value')");
    }
}
mysqli_close($con);

我希望我的数据库是：

          | id | id_page | url |

          | 1    | 1       | http://jjjjjjjjj |

          | 2    | 1       | http://jjjjjjjjj|  
          | 3    | 1       | http://jjjjjjjjj| 

          ......

          | 1000 | 76      | http://jjjjjjjjj|

但结果：

| id | id_page | url |

| 1    | 1       | http://jjjjjjjjj |

| 2    | 1       | http://jjjjjjjjj|  
| 3    | 1       | http://jjjjjjjjj| 

          ......
| 500  | 35      | http://jjjjjjjjj| 

|  501 | 1      | http://jjjjjjjjj|

当插入id_page循环到35并返回开始1时。 $ hrefs是上面的multidimentions数组。有什么决心？

Answer 1

我会这样试试：



    foreach ($hrefs as $id_page =>  $href) {
        foreach ($href as $value) {
            mysqli_query($con, "INSERT INTO urls(`id_page`, `url`)
                        VALUES ('".$id_page."', '".$value."')");
        }
    }
    mysqli_close($con);

假设＆＃34; id＆＃34;在表格中设置为auto_increment。

编辑1：检查＆＃34;网址＆＃34;中的数据类型table：也许是你的＆＃34; id_page＆＃34;太小，不能容纳大价值。例如，将其设置为int（11）。

Edit2：如果存在任何性能问题，您应该只执行一个具有多个值的查询，例如：

$sql = 'INSERT INTO urls(`id_page`, `url`) VALUES ';
foreach ($hrefs as $id_page =>  $href) {
    foreach ($href as $value) {
        $sql .= "('".$id_page."','".$value."'),";
    }
}
$sql = substr($sql, 0, -1); // delete last comma
mysqli_query($con, $sql);
mysqli_close($con);
