Answer 1

the list is obviously generated, so you'd have better luck fixing the generator, but if you're stuck with this one list, the below should parse it the way you want:

$langs_ar = array();
$codes_ar = array();
$families_ar = array();

foreach(preg_split('/[
]+/', $codes) as $line)
{   
    if (preg_match('/^(\S+\s*\S+)\s+(\S{2})\s+(\S.*\S)\s*$/', $line, $matches))
    {   
        $langs_ar[] = $matches[1];
        $codes_ar[] = $matches[2];
        $families_ar[] = $matches[3];
    }                                                                                                                                             
}

Oh, and instead of 3 arrays, I'd recommend one array storing hashes for the 3 fields instead; that or make your own objects with the 3 properties lang, code, and family.

Edit: a much shorter way to do the same is this:

preg_match_all('/^(\S+\s*\S+)\s+(\S{2})\s+(\S.*\S)\s*$/m', $codes, $matches, PREG_SET_ORDER);
var_dump($matches);

$matches is now an array of "objects" for all your lines where indexes:

• 0 is the full line
• 1 is the language
• 2 is the code
• 3 is the family

just iterate over that to do whatever you want.
