php - Can I use less isset lines to loop through array keys?

Is there a way to "DRY" (don't repeat yourself) this code, or do I need all these "isset" lines? I have lots of items to process just like this one, only IF they are selected. I am using FPDF. I would really like to shorten the processor code if possible! :)

function Item3l() {
if (isset($_POST["item3lQty"][0]) && !empty($_POST["item3lQty"][0]) || 
isset($_POST["item3lQty"][1]) && !empty($_POST["item3lQty"][1]) ||
isset($_POST["item3lQty"][2]) && !empty($_POST["item3lQty"][2]) ||
isset($_POST["item3lQty"][3]) && !empty($_POST["item3lQty"][3]) ||
isset($_POST["item3lQty"][4]) && !empty($_POST["item3lQty"][4]) ||
isset($_POST["item3lQty"][5]) && !empty($_POST["item3lQty"][5])) {
$item3lQty = $_POST['item3lQty'];
$itm3l     = $_POST['itm3l'];
$des3l     = $_POST['des3l'];
$clr3l     = $_POST['clr3l'];
$this->SetFont('Arial', '', 10);
$this->SetFillColor(242);
$this->SetLineWidth(1); 
$this->SetX(33);
    $this->Cell(97, 20, $itm3l, 'LRB', 0, 'L');
    $this->Cell(300, 20, $des3l, 'LRB', 0, 'L');
    $this->Cell(95, 20, $clr3l, 'LRB', 0, 'L');     
    $this->Cell(28, 20, $item3lQty[0], 'LRB', 0, 'C');
    $this->Cell(28, 20, $item3lQty[1], 'LRB', 0, 'C');
    $this->Cell(28, 20, $item3lQty[2], 'LRB', 0, 'C');
    $this->Cell(28, 20, $item3lQty[3], 'LRB', 0, 'C');
    $this->Cell(28, 20, $item3lQty[4], 'LRB', 0, 'C');
    $this->Cell(28, 20, $item3lQty[5], 'LRB', 0, 'C');
    $this->Cell(28, 20, '', 'LRB', 0, 'C');
    $this->Cell(38, 20, array_sum($item3lQty), 'LRB', 1, 'C');

I would have possibly dozens more items...
