我有一个通过SQL查询创建的数组 $ export ，后来对其进行了格式化。数组现在看起来像这样（这些是整个数组的最后2个数组）
[6136] => Array
(
[id_product] => 247
[product_name] => Verte Home - vzor B.7.
[id_attribute] => 181
[attribute_name] => Premium - Drážka - Tloušťka J (260-280mm)
[price] => Array
(
[0] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "1"
["price_impact"] => 4099.173554
)
[1] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "2"
["price_impact"] => 4099.173554
)
[2] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "3"
["price_impact"] => 4099.173554
)
)
)
[6137] => Array
(
[id_product] => 247
[product_name] => Verte Home - vzor B.7.
[id_attribute] => 182
[attribute_name] => Premium - Drážka - Tloušťka K (280-300mm)
[price] => Array
(
[0] => Array
(
["id_attribute"] => 182
["id_custo_group"] => "1"
["price_impact"] => 4099.173554
)
[1] => Array
(
["id_attribute"] => 182
["id_custo_group"] => "2"
["price_impact"] => 4099.173554
)
[2] => Array
(
["id_attribute"] => 182
["id_custo_group"] => "3"
["price_impact"] => 4099.173554
)
)
)
但是，如果我现在将其放入此foreach循环中，并只打印嵌套的 price 数组
foreach ($export as $attribute){
echo '<pre>';
echo print_r($attribute['price']);
echo '</pre>';
}
我得到了（同样，整个数组的最后两个数组）
Array
(
[0] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "1"
["price_impact"] => 4099.173554
)
[1] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "2"
["price_impact"] => 4099.173554
)
[2] => Array
(
["id_attribute"] => 181
["id_custo_group"] => "3"
["price_impact"] => 4099.173554
)
)

请注意，最后一个数组中的id_attribute与源$ export数组中的id_attribute不同。仅在整个数组的最后一个嵌套数组中会发生这种情况。
我不知道为什么会这样，所以任何帮助将不胜感激。
