I have a functon that is passed an array of url's. I am extracting data from each webpage and then assigning each piece of data to an array. Here's my function:

 function getitems ($urls) {
  $iteminfo = array();
  foreach($urls as $link) {
   $circdl = my_curl($link);
   $circqp = htmlqp($circdl,'body');
   $itemtitle = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('title');
   $itemlink = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('src');
   $itemdesc = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('alt');
   $iteminfo[][] = $itemtitle;
   //$iteminfo[$itemtitle][] = $itemlink;
   //$iteminfo[$itemtitle][] = $itemdesc;
  }
    return $iteminfo;  
 }

I want the array to look like this:

 Array ( [0] => Array ( [0] => title [1] => link [2] => desc ) [1] => Array ( [0] => title [1] => link [2] => desc ) [2] => Array ( [0] => title [1] => link [2] => desc ) )

But I can't wrap my head around how to additional fields to the sub-arrays.

try something like this

function getitems ($urls) {
    $iteminfo = array();
    $i = 0;
    foreach($urls as $link) {
        $circdl = my_curl($link);
        $circqp = htmlqp($circdl,'body');
        $itemtitle = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('title');
        $itemlink = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('src');
        $itemdesc = $circqp->branch()->find('div[class="col-item"]')->children('img')->attr('alt');
        $iteminfo[$i][] = $itemtitle;
        $iteminfo[$i][] = $itemlink;
        $iteminfo[$i][] = $itemdesc;
        $i++;
    }
    return $iteminfo;  
}

Everything is ok, you just have to assign index to each of your rows.

If i understand you correctly...

$iteminfo[] = array($itemtitle, $itemlink, $itemdesc);

You could easily replace 

$iteminfo[][] = $itemtitle;
//$iteminfo[$itemtitle][] = $itemlink;
//$iteminfo[$itemtitle][] = $itemdesc;

with 

$iteminfo = array($itemtitle, $itemlink, $itemdesc);

You can do this because the syntax 

$array = $element; // where     $array = array();

is just another way to add element to an array in PHP and $element can be an array() as well.
