删除多维数组中的元素并保存 [英] remove element in multidimensional array and save

问题描述

我想弄清楚如何删除一个主要元素及其所有兄弟元素，然后再保存数组.

I am trying to figure out how to remove one main element and all its siblings and save the array afterwards.

这是我得到的:

$my_array = Array
(
    [0] => Array
        (
            [username] => Pete
            [userid] => 2
        )

    [1] => Array
        (
            [username] => James
            [userid] => 4
        )

     [2] => Array
        (
            [username] => John
            [userid] => 3
        )

) 

现在，我想要做的是删除用户 ID 为 4 的元素，然后将其全部保存回 $my_array，如下所示:

Now, what i want to do is to remove the element in where I have the userid 4 and then save it all back into $my_array like this:

$my_array = Array
(
    [0] => Array
        (
            [username] => Pete
            [userid] => 2
        )

     [2] => Array
        (
            [username] => John
            [userid] => 3
        )

)

这能做到吗?如果是的话......如何???

Can this be done? and if yes... How???

提前致谢:-)

推荐答案

试试这个:

foreach ($array as $key => $value) { 

    if ($value["userid"] == 4) { unset($array[$key]); }

}
