在PHP多维数组中搜索键并获取其值

我有一个名为

$array

的数组，其中包含以下数据

Array(
    [0] => Array(
        [month_count] => January
        [atmos_gb] => 4
        [atmos_h3] => 16
        [waterh3_river] => 8
        [waterh3_pond] => 1
    )
    [1] => Array(
        [month_count] => February
        [atmos_gb] => 4
        [atmos_h3] => 8
        [waterh3_river] => 5
        [waterh3_pond] => 0
    )
    [2] => Array(
        [month_count] => March
        [atmos_gb] => 5
        [atmos_h3] => 7
        [waterh3_river] => 5
        [waterh3_pond] => 0
    )
    [3] => Array(
        [month_count] => April
        [atmos_gb] => 0
        [atmos_h3] => 2
        [waterh3_river] => 2
        [waterh3_pond] => 0
    )
)

我想获取特定单元格的值，例如

[2][atmos\u gb]

---

如何获取此值？

是什么阻止您执行echo$array[2][atmos_gb]？如果您想获得每列的

atmos\u gb

值，可以利用PHP函数：

$atmos\u gb\u values=array\u column（$myArray，'atmos\u gb'）。。。如果您正在运行PHP>=5.5.0，如果您想变得非常聪明，只需获得
[2][atmos\u gb]
的值，您可以这样做：
$atmos\u gb\u 2=array\u column（$myArray，'atmos\u gb'）[2]
