php display multilevel treenode menu recursive - php

Question

I have a post regarding this which was answered though I now have a different problem related to the same topic. You may want to reference here for the original question. php display multilevel treenode menu
Now that the array is displaying by tree-node, it seems that it is not fully recursive. I notice that when the first element is a child node, it is not displaying as a child.
I tried doing a krsort then ksort.
function getChildren(&$rows, $p = 0) {
$r = array();
krsort($rows);
foreach($rows as $row_id => $row) {
if ($row['parent_node']==$p) {
$r[$row['product_category_code']] = getChildren($rows, $row['product_category_code']);
unset($rows[$row_id]);
}
}
ksort($rows);
return $r;
}
Here's the structure of the array:
array
0 =>
array
'product_category_code' => string 'akamia' (length=6)
'product_category_desc' => string 'Akamia' (length=6)
'parent_node' => string 'summer-dress' (length=12)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-04-01 10:03:42' (length=19)
'modified_by' => string '1' (length=1)
'modified_date' => string '2014-04-01 10:03:47' (length=19)
1 =>
array
'product_category_code' => string 'bracelets' (length=9)
'product_category_desc' => string 'Bracelets' (length=9)
'parent_node' => string '' (length=0)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-03-14 22:04:08' (length=19)
'modified_by' => string '1' (length=1)
'modified_date' => string '2014-03-14 22:09:05' (length=19)
2 =>
array
'product_category_code' => string 'floral-dress' (length=12)
'product_category_desc' => string 'Floral Dress' (length=12)
'parent_node' => string '' (length=0)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-03-14 22:09:49' (length=19)
'modified_by' => string '1' (length=1)
'modified_date' => string '2014-04-01 10:03:30' (length=19)
3 =>
array
'product_category_code' => string 'flowery-bracelets' (length=17)
'product_category_desc' => string 'Flowery Bracelets' (length=17)
'parent_node' => string 'bracelets' (length=9)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-03-14 22:09:16' (length=19)
'modified_by' => string '1' (length=1)
'modified_date' => string '2014-03-30 19:08:44' (length=19)
4 =>
array
'product_category_code' => string 'small-flowery-bracelets' (length=23)
'product_category_desc' => string 'Small Flowery Bracelets' (length=23)
'parent_node' => string 'flowery-bracelets' (length=17)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-03-14 22:08:35' (length=19)
'modified_by' => string '1' (length=1)
'modified_date' => string '2014-03-30 19:09:44' (length=19)
5 =>
array
'product_category_code' => string 'summer-dress' (length=12)
'product_category_desc' => string 'Summer Dress' (length=12)
'parent_node' => string '' (length=0)
'inactive' => string '0' (length=1)
'sort' => string '0' (length=1)
'created_by' => string '1' (length=1)
'created_date' => string '2014-03-14 22:09:29' (length=19)
'modified_by' => string '0' (length=1)
'modified_date' => null
The output (without the krsort / ksort) is showing this, which is wrong:
Akamai
Bracelets
Flowery Bracelets
Small Flowery Bracelets
Floral Dress
Summer Dress
This should be the output:
Bracelets
Flowery Bracelets
Small Flowery Bracelets
Floral Dress
Summer Dress
Akamai

Answer 1

Never mind, I got the answer. The $p on function getChildren(&$rows, $p = 0) should be $p = '' instead of a zero (0) since the parent node on the array is empty. Silly me. XD
