使用嵌套的 foreach 循环从数组中获取值
Fetch values from an array using nested foreach loop
我有一个很长的数组，我希望从中获取所有值并将其存储在一个单独的变量中，然后将每个值存储在数据库中。
我的数组是：
Array
(
[success] => 1
[categories] => Array
(
[0] => Array
(
[category_id] => 39
[name] => BAGS
[categories] => Array

[category_id] => 59
[name] => Handcrafted Purses
[categories] =>
[status] => 1
)
[1] => Array
(
[category_id] => 45
[parent_id] => 39
[name] => Laptop Bag
[categories] =>
[status] => 1
)
)
[status] => 1
)
[1] => Array

[category_id] => 40

)
)
[status] => 1
)

我可以使用以下代码获取此数组的外部值：
if (!empty($array))
{
foreach ($array['categories'] as $category)
{
echo $category['category_id'];
echo "<br>";
}
}
我得到的值为：
39
40
91
60
15
16
38
57
但我也想访问数组最里面的值。谁能告诉我如何创建嵌套循环？
如果您现在知道数组有多深，您只需在主循环中添加其他 foreach 循环即可。
if (!empty($array))
{
foreach ($array['categories'] as $category)
{
echo $category['category_id'];
echo "<br>";
if(isset($category['categories'])){
foreach($category['categories'] as $category2)
{
echo $category2['category_id'];
echo "<br>";
if (isset($category2['categories'])){
foreach($category2['categories'] as $category3)
{
echo $category3['category_id'];
echo "<br>";
...
} }
}}
}
}
