Easing up code

[Lukas W.]

I've created a function that makes me ill by just looking at it, but I honestly don't know how to make it better at the moment. A stack of three foreach-loops can't be the solution however, that's for sure...


The Code:

        foreach($params['templates'] as &$templateCategory) {                                   // for every category
            if(isset($templateCategory['templates'])) {                                         // templates exist?
                foreach($templateCategory['templates'] as &$template) {                         // for every template
                    $arrayForums    = unserialize($template['forums']);                         // all forums
                    $arrayRMC       = unserialize($template['resource_manager_categories']);    // all categories
                
                    $forums         = array();
                    $rmcs           = array();
                 
                    foreach($arrayForums as $forum)
                        if(!($forum === 'all'))
                            $forums[] = $nodes[$forum]['title'];                                    // get forum names
                    foreach($arrayRMC as $rmc) {
                        if(!($rmc === 'all'))
                            $rmcs[] = $categories[$rmc]['category_title'];                          // get category names
                    }
                 
                    $template['forums'] = implode(', ', array_merge($forums, $rmcs));           // merge and implode arrays to generate string
                }
            }
        }

And examples for the variables (I've removed all unnecessary columns to make it easier to read and handle):

$nodes

Array
(
    [5] => Array
        (
            [node_id] => 5
            [title] => Groups
        )
)

$categories

Array (
[3] => Array
        (
            [resource_category_id] => 3
            [category_title] => Child Category
        )
)

$params['templates']

Array
(
    [1] => Array
        (
            [category_id] => 1
            [templates] => Array
                (
                    [0] => Array
                        (
                            [template_id] => 1
                            [forums] => a:4:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:2:"12";i:3;s:1:"5";}
                            [resource_manager_categories] => a:3:{i:0;s:1:"1";i:1;s:1:"3";i:2;s:1:"2";}
                        )

                    [1] => Array
                        (
                            [template_id] => 2
                            [forums] => a:1:{i:0;s:2:"12";}
                            [resource_manager_categories] => a:1:{i:0;s:3:"all";}
                        )
                )
        )

)

The only thing that matters is the output here: a string containing the name of all selected forums and resource manager categories in the form "Main Category, Main Forum, Forum 2, Groups, Example Category, Child Category, Different Category". If someone has an idea, I'd be glad to hear it.
