Question

I’m currently adding fileID to idarray[] and then do a foreach. But in addition to fileID I also need serverID and id in the array and the foreach, how do I do this? So basically I need to find out how to add 2 more values to the array and then also use those extra values in the foreach.

$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
        $idarray[] = $row['fileID'];
}

foreach ($idarray as $value)
{
    $result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$value AND removed=0 AND serverID=$XXXserverIDhereXXX");
    while($row = mysql_fetch_array($result))
    {
        $sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
        mysql_query($sql) or die(mysql_error());
    }
}

Why not just store the whole row into an array?

$rowarray[] = array();
$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
        $rowarray[] = $row;
}

foreach ($rowarray as $row)
{
    $fileid = $row['fileID'];
    $serverid = $row['serverID'];
    $result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$fileid AND removed=0 AND serverID=$serverid");
    while($row = mysql_fetch_array($result))
    {
        $sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
        mysql_query($sql) or die(mysql_error());
    }
}

But really, your whole code piece here is a mess. You can accomplish this way more efficiently using JOINs.
