Make my loop something recursive
I can't quite get my head around this one. I've got an array like so:
Array
(
[0] => Array
(
[content_id] => 23
[content_level] => 1
[content_left] => 2
[content_right] => 3
[content_type] => link

[content_name] => home
[content_link] => a:3:{s:3:"url";s:7:"_link_/";s:6:"target";s:5:"_self";s:5:"title";s:4:"home";}
[date_modified] => 2010-07-16 10:29:44
[content_path] =>
)
[1] => Array
(
[content_id] => 13
[content_level] => 1

[content_path] => products
)
[8] => Array

[content_right] => 32
[content_type] => module

[content_name] => SkyMax Series
[content_link] =>
[date_modified] => 2010-08-13 13:24:18
[content_path] => products/SkyMax-Series
)
[9] => Array
(
[content_id] => 0
[content_name] => SkyMax Patio Retractable Roof System
[content_path] => products/SkyMax-Series/SkyMax-Patio-Retractable-Roof-System-1281674658
[content_item] => 1

[content_left] => 25
[content_right] => 32
[content_type] => page
[date_modified] => 2010-08-13 15:14:36
)
And I need to loop through it and turn it into something prettier based on content_path. I want it to be a multidimensional array with the element "item" containing the content_id,name,path etc and the rest of the elements relating to other menu items.
This is my code:
foreach($menu as $key => $item)
{
$parts = explode('/',$item['content_path']);
switch (count($parts))
{
case 3:
$ul[$parts[0]][$parts[1]][$parts[2]]['item'] = $item;
break;
case 2:
$ul[$parts[0]][$parts[1]]['item'] = $item;
break;
case 1:
$ul[$parts[0]]['item'] = $item;
break;
}
}
It works fine, the output being
Array

But it won't work with any more then 3 levels for obvious reasons. Anyone got some ideas on making this recursive? maybe using a function that calls itself perhaps?
A recursive function isn't necessary, just a for loop will do:
$parts = explode('/',$item['content_path']);
$array = &$ul;
for ($i = 0; $i < count($parts); $i++)
$array = &$array[$parts[$i]];
$array['item'] = $item;
This loops over $parts, with each iteration obtaining a reference to the next dimension of $ul.
