Question

Okay, after pounding my head against the wall for about 2 hours, I need help. I have a query that pulls “comments” based on a users “followers”. The followers have a unique id, and lets say just for ease of use, their id’s are 4 and 5. The query returns all followers, so there could be way more than just two rows. That query creates a foreach that I want to say for each “follower” execute this query. Then, that query needs to create a fetch_assoc() so that the data can be recalled later on down the page. The way I have the code right now, it only shows postings from follower 4, and not 5. I have tried using counters to append variable names so that they wont get overwritten each time, but it doesnt help. Thanks a lot!

$sqlb ="SELECT myfriend_ID FROM friends WHERE my_id = '$myuid'";
$resultb = mysql_query($sqlb,$db);
$numa = mysql_num_rows($resultb);
if($numa)
{
    while(($follower = mysql_fetch_assoc($resultb))) {
        $followers[] = $follower;
    }
}
$i=0;
foreach($followers as $follower)
{
    $i++;
    $fnub = $follower['myfollower_ID'];//this will print 4 and 5
    $fnum = $fnub;

    $sql = "SELECT * FROM usr, feed, course WHERE usr.usr_id = '$fnum' AND 
             feed.usr_id = '$fnum' AND course.usr_id = '$fnum' ORDER BY Feed_ID desc";
    $result = mysql_query($sql,$db);
    $num.$fnum = mysql_num_rows($result);
    if($num.$fnum)
    {
        while(($feed = mysql_fetch_assoc($result))) {
            $feeds[] = $feed;
        }
        foreach($feeds as $feed)
        {
            echo $feed['comment'];
        }
    }
}

$sqlb ="SELECT myfriend_ID FROM friends WHERE my_id = '$myuid'";
$resultb = mysql_query($sqlb,$db);
$follower = array();

if(mysql_num_rows($resultb))
{
   while(($follower = mysql_fetch_assoc($resultb))) {
      $fnum = $follower['myfriend_ID'];//what is the column name
      $sql = "SELECT * FROM usr, feed, course WHERE usr.usr_id = '$fnum' AND feed.usr_id = '$fnum' AND course.usr_id = '$fnum' ORDER BY Feed_ID desc";
      $result = mysql_query($sql,$db);
      if( mysql_num_rows($result))
      {
         while(($feed = mysql_fetch_assoc($result))) {
           echo $feed['comment'];
       }
    }
}

And you must combine these two queries into single. But I am not too good in SQL.
Probably some one other can help.
