generating arrays from main multi-dimensional array

Hi!
For a list of projects, I have no access to a database, so I decided to create a folder for each project. The names of these folders are meant to categorize the projects by client and media:

PHP Code:


$projects = array(
                'media01-client1-project01_1',
                'media01-client1-project01_2',
                'media01-client2-project01_1',
                'media01-client2-project01_2',
                'media01-client2-project01_3',
                'media02-client3-promo02_1',
                'media02-client1-promo02_1',
                'media02-client4-promo02_1',
                'media02-client4-promo02_2',
                'media03-client3-project03_1',
                'media03-client3-project03_2',
                'media03-client2-project03_1',
                'media03-client2-project03_2',
                'media03-client2-project03_3',
                'media04-client1-project04_1',
                'media04-client4-project04_1',
                )

I asked on another forum how I could create individual arrays out of this one using the dash delimiter from the strings. i was given the following:

PHP Code:


foreach ($projects as $value)
{
    $explode = explode('-', $value);
    $multi_projects[$explode[0]][$explode[1]][] = $explode[2];
}

But how do I use this to generate arrays for the media and clients?

I.E.:

PHP Code:


$media = array(
                'media01',
                'media02',
                'media03',
                'media04',
                )


$clients = array(
                'client1',
                'client2',
                'client3',
                'client4',
                )

What I would then like to do is generate sub-arrays of related projects per media or client.

I.E.:

PHP Code:


$projects_by_media = array(
                'media01=>array(
                                'media01-client1-project01_1',
                                'media01-client1-project01_2',
                                'media01-client2-project01_1',
                                'media01-client2-project01_2',
                                'media01-client2-project01_3'
                                )',
                'media02=>array(
                                'media02-client3-promo02_1',
                                'media02-client1-promo02_1',
                                'media02-client4-promo02_1',
                                'media02-client4-promo02_2'
                                )',
                'media03=>array(
                                'media03-client3-project03_1',
                                'media03-client3-project03_2',
                                'media03-client2-project03_1',
                                'media03-client2-project03_2',
                                'media03-client2-project03_3'
                                )',
                'media04=>array(
                                'media04-client1-project04_1',
                                'media04-client4-project04_1'
                                )'
                )


$projects_by_clients = array(
                'client1=>array(
                                   'media01-client1-project01_1',
                                'media01-client1-project01_2',
                                'media02-client1-promo02_1',

                                )',
                'client2=>array(
                                   'media01-client2-project01_1',
                                'media01-client2-project01_2',

You could use a regular expression match (preg_match() would be a possible function) and create a media array and a client array by looping through the original array and returning all of the matches.

If you are not familiar with regular expressions, then here is a good website that helped to get me started: weblogtoolscollection.com

Hope this helps.
