获取php中最后一个数组的数量

Question

我在codeigniter工作。我有一个像父母一样的数组，它的子项显示在下面。

Array
(
[id] => 27
[Name] => MUKESH CHUNAWALA
[children] => Array
    (
        [0] => Array

                [amnt] => 616
            )
    )

现在，我想获取最后一个id的数量。这里，最后一个id是27.所以我想要获取27个id的数量。那么我应该编写什么代码才能获得最后一个ID？

我想从父数组中获取Name，那么我应该编写什么代码？

Answer 1

$last = end($your_array['children']);
$amt = $last['amnt'];

请注意end()使数组的内部指针前进到最后一个元素。
