SQL / PHP数组,服务器警告

I'm trying to pull info off of a db and store it in an array. $row is returning information, while $categories is lazy and doesn't do anything. There's a log warning on the server that says:

PHP Notice: Undefined index: CATID in /www/zendsvr/htdocs/public/test/index.php on line 29

CATID is auto-increment PK from about 1 to 1100. I've also assigned $row entries to individual variables successfully, but this array just doesn't want to work.

$query = 'SELECT CATID, CATDSC, CATPID, CATFEAT, CATURL FROM cecart.categories
WHERE CATURL!=\'\' ORDER BY CATFEAT DESC, RAND()';

while (($row = $stmt->fetch(Zend_Db::FETCH_ASSOC)) !== false) {
  $categories[$row['CATID']] =
    array('CATID' => trim($row['CATID']),
          'CATDSC' => trim($row['CATDSC']),
          'CATPID' => trim($row['CATPID']),
          'CATFEAT' => trim($row['CATFEAT']),
          'CATURL' => ($cat_img_dir . trim($row['CATURL'])));
  print($row['CATID'] . ' | ' . $categories['CATID']); // line 29
}

line 29 outputs: x | should be x | x if the array was working properly

    I'm guessing you meant to look up $categories[$row['CATID']], not $categories['CATID']. There is no $categories['CATID'].
