PHP访问多维数组中的值

Question

我有一个名为$ ticket_quantities的数组来自API，当我将var转储出来时

array(1) {
    [4128] => array(1) {
        [168] => array(2) {
            [7] => int(4)[8] => int(2)
        }
    }
}

如何访问[7] =＆gt; int（4）value和[8] =＆gt; int（2）value？

Answer 1

应该是

$ticket_quantities[4128][168][7]
$ticket_quantities[4128][168][8]

Answer 2

如果对传入数组的未定义键使用array_keys函数，会更好。看看这个样本：

// rebuld Your array
$arr = array(4128 => array(168 => array(7 => 4,8 => 2)));
// get node of first level
$myArr = $arr[array_keys($arr)[0]];
// get node of second level
$myArr = $myArr[array_keys($myArr)[0]];

// get firs and second node from threed level
$One = $myArr[array_keys($myArr)[0]];
$Two = $myArr[array_keys($myArr)[1]];
print $One;
print '<hr>';
print $Two;
