Php 将元素添加到现有数组中

我有一个如下所示的数组：

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [migr] => 0
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [0] => Array
            (
                [migr] => 0
            )

    ) )

如何在现有阵列中添加新字段，使其看起来像这样：

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [migr] => 0
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [0] => Array
            (
                [migr] => 0
            )

    ) )

我尝试了阵列推送，但得到了如下结果：

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [migr] => 0
    ) )

Array(
[0] => Array
    (
        [id] => 39
        [countNew] => 0
        [nume] => Ardeleanu
        [0] => Array
            (
                [migr] => 0
            )

    ) )

Justr尝试：

$input = array(/* your data */);
$input[0]['migr'] = 0;

或：

Justr尝试：

$input = array(/* your data */);
$input[0]['migr'] = 0;

或：

$foo[0]['migr']=0

有道理！它很管用，谢谢<代码>$foo[0]['migr']=0有意义！它很管用，谢谢！
