    if your divs are static to 4 counts you can just use the condition

    for($i=1,$n=4; $i<=$n; $i++)
    {
    $addedString = $i=1 || $i=$n ? 'add your string here' : '';
    echo '<div class="grid_4 alpha center" '. $addedString .'>';
    }

    nice suggestion, going to try it out. but i need two different classes

    i have found this to work also
    ok found it
    
$extraclass = $i % 4;
		if($extraclass==0)		
			$extraclass = 'alpha';
		elseif($extraclass==3)		
			$extraclass = 'omega';
		else 
			$extraclass = '';
		$output .= "<div class='grid_4 $extraclass center'>
    Code (markup):
