【问题描述】：
我有一个多维数组，我正在尝试使用 foreach 从中提取值。
它是检索到的 JSON 格式，所以我使用json_decode 将其转换为关联数组。
该数组包含各种产品的定价信息。我正在努力解决的问题是它包含每个产品的多个嵌套数组。
因此，我不确定如何将其集成到foreach。
数组 $arr:
Array

[product] => Array

以上部分从[product] 重复每个产品 ID ([pid]) - 我无法将整个数组放入帖子中，所以这里有一个链接 - http://pastebin.com/0qgh5scG
我想要实现的是将数组中每个产品 ID [pid] 的名称描述和 EACH Monthly* 价格提取到它自己的数组中，该数组变量名称是关联的 [pid]。
*（月价其实是年价，只是模块将数据存入数据库的一种奇葩方式）
我已经尝试过foreach：
$arr = json_decode($jsondata, true); # Decode JSON String
foreach ($arr['products']['product'] as $num) {
$pid = $num['pid'];
$yearlycosts = $arr['configoptions']['configoption']['0']['options']['option'][0]['pricing']['GBP']['monthly'];
echo $pid;
echo $yearlycosts;
}
产品 ID，检索正常，但是我到底如何为每个产品 ID [pid] 提取多个 [name] 和相关的多个 [monthly] 值？
我是否需要在现有的foreach 中包含foreach？
最终我想将这些值传递给新数组，每个数组都以其对应的[pid] 值命名。但我认为这对我来说是一个单独的问题/挑战。
我希望我在上面说得通。我是数组的新手，在搜索了很多示例时，没有发现任何具有像上述那样复杂的数组，或者具有唯一命名的部分。
【问题讨论】：
-
api 的数组结构没有多大意义。他们的文档有解释吗？
-
我知道！这是WHMCS 的 API（计费“解决方案”）。老实说，他们的文档在这样的事情上并不是很好。支持还有很多不足之处。
