Fetch values from an array using nested foreach loop - php

Question

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.
The array that I have is:
Array

[success] => 1
[categories] => Array

[category_id] => 39
[name] => BAGS
[categories] => Array

[status] => 1
)
[1] => Array

[category_id] => 40
[name] => BOXERS
[categories] => Array
(
[0] => Array

[category_id] => 56
[parent_id] => 40
[name] => Women Boxers

)
)
[status] => 1
)
[2] => Array

)
[status] => 1
)
)
[status] => 1
)
[3] => Array
(
[category_id] => 60
[parent_id] => 0
[name] => Business Corporates
[image] =>
[categories] => Array

)
[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

)
[status] => 1
)
[4] => Array
(
[category_id] => 87
[parent_id] => 60
[name] => Shawls And Stoles
[image] =>

(
[0] => Array

[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
)
)
)
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>";
}
}
I got values as:
39
40
91
60
15
16
38
57
But I also wish to access the inner most values of the array. Can anyone tell how I can create a nested loop?

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>";
...
} }
}}
}
}
