Question

我有一个像这样的PHP数组和我放在循环上的数组。

Array
(
    [0] => Array
        (
            [topic_id] => 973
            [reply_id] => 3549
            [user_id] => 1
        )

    [1] => Array
        (
            [topic_id] => 973
            [reply_id] => 3551
            [user_id] => 1
        )

    [2] => Array
        (
            [topic_id] => 973
            [reply_id] => 3553
            [user_id] => 1
            [status] => 1
        )

    [3] => Array
        (
            [topic_id] => 973
            [reply_id] => 3555
            [user_id] => 1
            [status] => 1
        )

    [4] => Array
        (
            [topic_id] => 973
            [reply_id] => 4401
            [reply_author] => 28
            [user_id] => 1
            [status] => 1
        )

    [5] => Array
        (
            [topic_id] => 232
            [reply_id] => 4405
            [reply_author] => 28
            [user_id] => 1
            [status] => 1
        )

)

现在循环项目具有唯一ID ， ID与数组中的reply_id 相同。我希望根据reply_id 拆分每个数组。

所以，我想要的最终结果如下：

循环项目1（身份证号码：3549）

Array ( [topic_id] => 973 [reply_id] => 3549 [user_id] => 1 )

循环项目2（id：3551）

Array ( [topic_id] => 973 [reply_id] => 3551 [user_id] => 1 )

还有更多......

如何制作，请帮助。

编辑：在第一次回复后，我现在认为我理解你的意思。

$myListWithIds = array('3549','3551');
$idListCount = 2;

for($x = 0; $x < $idListCount; $x++)
{
    $key = array_search($myListWithIds[$x], array_column($myArray, 'reply_id'));
    echo "<pre>";
    print_r($myArray[$key]);
    echo "</pre>";
}

假设您的数组存储在变量$ myArray。
