This is the code i use to fetch the Data from the database, a preview of the DB can been seen on the bottom of this thread.

Code:
 $query = "SELECT post_id, actor_id, comments, likes FROM stream WHERE source_id = ".$user." LIMIT 500";
$result = mysql_query($query);
$count = count($result);
$total=$count;


 for ($i = 0; $i < $count; $i++)
 {

 $actor_id = $result[$i][actor_id];
$count_c  = $result[$i][comments][count];

if($count_c > 0){
    for ($a = 0; $a < $count_c; $a++){
          $comment_id = $result[$i][comments][comment_list][$a][fromid];

    }
}

  
$count_l  = $result[$i][likes][count];

if($count_l > 0){        
        for ($b = 0; $b < $count_l; $b++){
            $likes_id = $result[$i][likes][friends][$b];
       
   }        
}




}

This is how the information is stored in the DB

Code:

Ok here is my problem:

There is around 350 rows in the db.

All the variables $actor_id, $comment_id and $likes_id are all Social Security Numbers.

Now i want to group and sum how many entries there are of each unique social security number.

Say for example the number:

'65653171' came up
10 times as a $actor_id
5 times as a $comment_id
3 times as a $likes_id

and

'67418530' came up
5 times as a $actor_id
21 times as a $comment_id
3 times as a $likes_id

Then my query would display in order of most entries:
1.) 67418530 (29)
2.) 65653171 (18)


Thanks for the help, real brain teazer.
