Well, I'm not sure it's needed, to be honest. I have made us a simple example so you can have a play around. See for yourself if you think it's useful or not.

php Code:

function preg_split_callback($szPattern, $szSubject, $szCallback)
{
    if(!function_exists($szCallback))
    {
        return;
    }
    
    return $szCallback(preg_split($szPattern, $szSubject));
}

function split_last(array $aParts = array())
{
    foreach($aParts as &$pPart)
    {
        if(strpos($pPart, ';') === false)
        {
            continue;
        }
        
        list($pPart, $aParts[]) = explode(';', $pPart);
    }
    
    return $aParts;
}

$aParts = preg_split_callback('~\|~', 'a|b;c', 'split_last');

echo '<pre>';
print_r($aParts);
echo '</pre>';
