Subject: Changed comments' user index

Previously, the comments table referenced users by username. However, if user ever changed their username, everything would become messed up. To fix
this, the index has been changed to the user ID. This change obviously requires maintenance:

This SQL must be run: "ALTER TABLE `comments` ADD `user_id` INT( 11 ) NOT NULL AFTER `page_id`;"

This PHP will generate some SQL that must be run:

<?php

$getusers = "SELECT DISTINCT username FROM comments WHERE is_anon = 0";
$getusers2 = mysql_query($getusers);
while ($getusers3 = mysql_fetch_array($getusers2))
{
        $getuser = "SELECT * FROM phpbb_users WHERE username = \"" . $getusers3['username'] . "\"";
        $getuser2 = mysql_query($getuser);
        $getuser3 = mysql_fetch_array($getuser2);

        echo("UPDATE comments SET user_id = " . $getuser3['user_id'] . " WHERE username = \"" . $getuser3['username'] . "\" AND is_anon = 0;<BR>");
}

$getusers = "SELECT * FROM anon_commenters";
$getusers2 = mysql_query($getusers);
while ($getusers3 = mysql_fetch_array($getusers2))
{
        echo("UPDATE comments SET user_id = " . $getusers3['id'] . " WHERE username = \"" . $getusers3['username'] . "\" AND is_anon = 1;<BR>");
}

?>

This SQL must be run: "ALTER TABLE `comments` DROP `username`;"
