Parsing one col of multiple rows php

Question

I have e.g. the following data returned from a query, each name is an item:

id      name      comment
1       FF        hey
1       FF        hey back!
2       L

Don't confuse data access with output and you will have an easier time attacking this sort of problem.

//Fetch and Sort
$data = array();
while ($row = mysql_fetch_array($result)){
   $item = $row['item'];
   if(!isset($data[$item]) {
     $data[$item] = array():
   }
   $data[ = $data[$item][] = $row['comment'];   
}

//Output
foreach($data as $item => $comments) {
    echo '
'.$item.'
';
    foreach($comments as $comment) {
      echo '
'.$comment.'
'; 
    }
    echo '
';
}
