Question

I have table called comments with following structure:

id | entry_id | date | comment

I also have a table called entries with following structure:

entry_id | title | date | entry

I just want to show recent comments and entries, to which these comments were added.

Now I’m using this query:

SELECT c.id,
       c.date,
       c.comment,
       e.entry_id,
       e.title
FROM   entries e
       INNER JOIN comments c
        ON e.entry_id = c.entry_id
GROUP  BY c.date DESC
LIMIT  50

And I output the results so:

#entry_id
  1 hour ago:
  Some comment

#entry_id
  2 hours ago:
  Some comment    

Comments are ordered by date. What I’m trying to do is simply group comments by same entry_id, e.g.:

#entry_id
  1 hour ago:
  Some comment

  2 hours ago:
  Some comment without  repeating the `entry_id`

#other entry_id
  5 hours ago:
  Some comment

How would I do that? No need to write a code for me, just say how would you do that (in pseudo code, for example). This is comments grouping like on facebook or google+ stream, I hope you understand what I mean.

Used this: Grouping arrays in PHP

I think I shouldn’t write so much details about my MySQL tables structure, done it with PHP and arrays. Thanks to all for attention.

$groups = array();

foreach($items as $item)
    $groups[$item['value']][] = $item;
