recorrer array asociativo php

Question

Tengo una larga lista desde la cual deseo buscar todos los valores y almacenarlos en una variable separada, y almacenar cada valor en la base de datos.

La matriz que tengo es:

 Array
(
[success] => 1
[categories] => Array
(
[0] => Array
(
[category_id] => 39
[name] => BAGS
[categories] => Array

)
[status] => 1
)

[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

[status] => 1
)
[4] => Array
(
[category_id] => 15
[parent_id] => 0

)
[1] => Array

[category_id] => 2
[parent_id] => 15
[name] => Suits

)
)

Puedo obtener los valores externos de esta matriz usando este código:

if (!empty($array))
{
foreach ($array[''categories''] as $category)
{
echo $category[''category_id''];
echo "<br>";
}
}

Obtuve valores como:

39
40
91
60
15
16
38
57

Pero también deseo acceder a los valores más internos de la matriz. ¿Alguien puede decir cómo puedo crear un bucle anidado?

Si ahora cuán profunda es su matriz, simplemente puede agregar otros foreach-loops dentro de su ciclo principal.

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