问题描述
我有很长的阵列从中我希望获取所有的值，并将其存储在一个单独的变量中，每个值存储在数据库中。
I have a long array from which I wish to fetch all the values and store it in a separate variable, and store each value in database.
这是我的数组是：
Array
(
[success] => 1
[categories] => Array
(
[0] => Array
(
[category_id] => 39
[name] => BAGS
[categories] => Array
(
[0] => 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
[name] => BOXERS
[categories] => Array
(
[0] => Array
(
[category_id] => 56
[parent_id] => 40
[name] => Women Boxers
[status] => 1
)
)
[status] => 1
)
[2] => Array
(
[category_id] => 91
[parent_id] => 0
[name] => Business Corporate
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 92
[parent_id] => 91
[name] => Bags
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 93
[parent_id] => 92
[name] => Potli Bags
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
)
[status] => 1
)
[3] => Array
(
[category_id] => 60
[parent_id] => 0
[name] => Business Corporates
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 90
[parent_id] => 60
[name] => Art Cushions
[image] =>
[categories] =>
[status] => 1
)
[1] => Array
(
[category_id] => 67
[parent_id] => 60
[name] => Bags
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 77
[parent_id] => 67
[name] => Potli Bags
[image] =>
[categories] =>
[status] => 1
)
[1] => Array
(
[category_id] => 76
[parent_id] => 67
[name] => Smart Bags
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
[2] => Array
(
[category_id] => 86
[parent_id] => 60
[name] => Fashion Jewellery
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 88
[parent_id] => 86
[name] => Coming Soon - Products Uploading
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
[3] => Array
(
[category_id] => 61
[parent_id] => 60
[name] => Men Footwear
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 65
[parent_id] => 61
[name] => Canvas Loafers
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
[4] => Array
(
[category_id] => 87
[parent_id] => 60
[name] => Shawls And Stoles
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 89
[parent_id] => 87
[name] => Coming Soon - Products Uploading
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
)
[status] => 1
)
[4] => Array
(
[category_id] => 15
[parent_id] => 0
[name] => ETHNIC WEAR
[image] =>
[categories] => Array
(
[0] => Array
(
[category_id] => 28
[parent_id] => 15
[name] => Designer Lehngas
[image] =>
[categories] =>
[status] => 1
)
[1] => Array
(
[category_id] => 2
[parent_id] => 15
[name] => Suits
[image] =>
[categories] =>
[status] => 1
)
)
[status] => 1
)
)
)
我能够使用这种code来获取这个数组的外值：
I am able to fetch the outer values of this array by using this code:
if (!empty($array))
{
foreach ($array['categories'] as $category)
{
echo $category['category_id'];
echo "<br>";
}
}
我值：
39
40
91
60
15
16
38
57
不过，我也希望访问阵列内最值。谁能告诉我怎样才能创建一个嵌套的循环？
But I also wish to access the inner most values of the array. Can anyone tell how I can create a nested loop?
推荐答案
如果你现在有多深你的数组是你可以只是简单的主循环中添加其他的foreach循环。
If you now how deep your array is you can just simply add other foreach-loops within your main loop.
if (!empty($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>";
...
} }
}}
}
}
