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

First select the number of friends that the user has:

"SELECT COUNT(*) as numFriends FROM friends WHERE member_id='".$_SESSION['userid']."'

...put that into a variable, let's call it "$numFriends" Then:

for($z=0;$z<6;$z++)
{
   $randomFriendIndex = rand(1,$numFriends);
   //Get the friend at that index
}
