问题描述
我有 PHP 数组。我只需要在 foreach 中获取产品 ID。我怎样才能做到这一点？只需要一些产品 ID 列表。我如何在 foreach 中解析数组？我这样试过 ($numenclatureS['terminalGroupStopLists'][0]['items'] as $product)
Array
(
[correlationId] => 3b1ba055-c216-49de-9f85-209f68adf55b
[terminalGroupStopLists] => Array
(
[0] => Array
(
[organizationId] => 7e3e9763-67a8-43ec-a663 9daf00f98945
[items] => Array
(
[0] => Array
(
[terminalGroupId] => 743a13f7-c0b1-41b6-b45a-2be970abff19
[items] => Array
(
[0] => Array
(
[balance] => 0
[productId] => 137e576d-ac4e-4d60-8da2-9048e56c063a
)
[1] => Array
(
[balance] => 0
[productId] => 06ea7ef2-8067-4b0b-9376-d1439a70f110
)
[2] => Array
(
[balance] => -8
[productId] => 07040e16-7ae9-4f9e-a7c8-182ab89453f0
)
[3] => Array
(
[balance] => 0
[productId] => e423da4a-b12e-4d93-a557-7cace4f565b9
)
)
)
)
)
)
)
解决方法
如果我这样做就可以了
<?php
$zzz = $numenclatureS['terminalGroupStopLists'];
$zzz1 = $zzz[0]['items'][0];
$zzz2 = $zzz1['items'];
?>
<?php foreach ($zzz2 as $product): ?>
<?php echo $product['productId']; ?>
<br />
<?php endforeach; ?>
也许有更简单的方法？
