TalkPHP - pregreplace & minor bbcoding

Ok, heres my deal.

Code:

echo '<tr align="center">';

foreach ($row as $key => $value) {

    if ($key == "id"){

    echo '<td bgcolor="'.$bg.'" ><a href="index.php?page=edit&id='.$value.'">'.$value.'</a></td>';

    }else{

        if ($key == "comment"){

            echo '<td bgcolor="'.$bg.'" width="25%" >'.$value.'</td>';}

                     else{echo '<td bgcolor="'.$bg.'" >'.$value.'</td>';

         }

    }

  }

    echo "</tr>";

query for above code

Quote:

sql ="SELECT id, username, email, first_name, last_name, nonprofit_date, packet1, packet2, comment
FROM users
WHERE level=1
ORDER by ".$order." ".$dir."
LIMIT ".$limit."
";

when i do this, my comment cell is a bunch of comments. each seperate comment is surrounded like bbcode [my comment1] [mycomment2]

what i need to do is take this part:

Code:

if ($key == "comment"){

            echo '<td bgcolor="'.$bg.'" width="25%" >'.$value.'</td>';}

                     else{echo '<td bgcolor="'.$bg.'" >'.$value.'</td>';

         }

and i need to parse out that indevidual if() statement, and make it parts out each [] and put it on a seperate line. i know i need to use a preg_replace. but preg_replace is so forigne to me... i can't figure out how to get it to work.

any suggestions?
