PHP MySQL select random rows

Question

I have a problem selecting 6 random friends

This is the query I\'ve got so far:

$result = num_rows(\"SELECT * FROM friends WHERE member_id = \'\".$_S         


        

Answer 1

If you use:

  SELECT * 
    FROM friends 
   WHERE member_id = '".$_SESSION['userid']."' 
ORDER BY rand() 
   LIMIT 6

If the person only has 3 friends, the query will only show those three - it doesn't mean that the query will always return six rows.
