PHP - 2D数组 - 循环数组键并检索它们的值？

I have an array that outputs like this:

我有一个输出像这样的数组：

1 => 
array
  'quantity' => string '2' (length=1)
  'total' => string '187.90' (length=6)

2 => 
array
  'quantity' => string '2' (length=1)
  'total' => string '2,349.90' (length=8)

I would like to loop through each array keys and retrieve the set of 3 values relating to them, something like this (which doesnt work):

我想循环遍历每个数组键并检索与它们相关的3个值的集合，类似这样（这不起作用）：

foreach( $orderItems as $obj=>$quantity=>$total)
{
    echo $obj;
    echo $quantity;
    echo $total;
}

Would someone be able to give some advice on how I would accomplish this, or even a better way for me to be going about this task. Any information relating to this, including links to tutorials that may cover this, would be greatly appreciated. Thanks!!

有人能够就如何实现这一目标提出一些建议，甚至是一个更好的方式让我去完成这项任务。任何与此相关的信息，包括可能涵盖此内容的教程链接，都将不胜感激。谢谢！！

2 个解决方案

#1

foreach( $orderItems as $key => $obj)
{
    echo $key;
    echo $obj['quantity'];
    echo $obj['total'];
}

Using the above.

使用上面的。

You need to read the docs on forEach() a little more, since your syntax and understanding of it is somewhat incorrect.

您需要更多地阅读forEach（）上的文档，因为您的语法和对它的理解有些不正确。

$arr = array(
    array('foo' => 'bar', 'foo2', 'bar2'),
    array('foo' => 'bar', 'foo2', 'bar2'),
);
foreach($arr as $sub_array) {
    echo $sub_array['foo'];
    echo $sub_array['bar'];
}

forEach() iteratively passes each key of the array to a variable - in the above case, $sub_array (a suitable name, since your array contains sub-arrays). So within the loop body, it's that you need to interrogate.

forEach（）迭代地将数组的每个键传递给变量 - 在上面的例子中，$ sub_array（一个合适的名称，因为你的数组包含子数组）。所以在循环体内，你需要询问。

#1

foreach( $orderItems as $key => $obj)
{
    echo $key;
    echo $obj['quantity'];
    echo $obj['total'];
}
