Php 结果仅显示在foreach内部

我试图获取会话数组中产品的数量，但由于某些原因，如果我有下面的代码，它就无法工作

$amount = $array->products['quantity'];

如果数组是一个多维数组，我使用下面的代码来获得压缩

$zip = $array->BT['zip'];

但是如果我使用foreach，我会得到我需要的结果（见下文）

问题是我有一个计算运费的foreach，它需要数量乘以重量，所以我不能使用上面的foreach，因为计算器使用不同的foreach

请参见下面的阵列打印：

请注意：我是php新手，任何帮助都会非常好

数组是否需要循环以获得结果，还是我遗漏了什么

---

感谢阅读。

我认为您可以使用以下代码访问。但不确定

$amount = $array->products[0]->quantity

---

如果您显示您的

数组

运行

var\u dump（$array）

并编辑问题以添加输出，这将非常有用。请参见上面的var_dump@MasterGray101你能不能

print\r（$array）

并更新您的答案。您想让我给您打印结果吗？现在可以吗？我无法在我的问题中添加打印结果，因为我达到了最大正文限制-我是否应该删除变量转储结果并将其替换为打印？是的，将变量转储替换为打印

$amount = $array->products[0]->quantity
