Creating a mysql database that holds a field of values, e.g. TLDs, with row 0 containing cx nu com org net, row 1 containing it at de us com, and so forth, a semi-annoying bug can be created with array_unique() that will insert null elements into the new array.  For example:
<? 
    $connection = mysql_connect("localhost","classicgames","classicgames"); 
    mysql_select_db("classicgames",$connection); 
    $query = "select votes from tldvote"; 
    $result = mysql_query($query); 
    $i = 0; 
    while($row = mysql_fetch_row($result)) { 
        $string = implode("",$row); 
        $tempArray = explode(" ",$string); 
        for($j = 0; $j < 5; $j++) { 
            $votes[$i][$j] = $tempArray[$j]; 
        } 
        $i++; 
    } 
    for($i = 0, $k = 0; $i < sizeOf($votes); $i++) 
        for($j = 0; $j < 5; $j++) { 
            $type[$k] = $votes[$i][$j]; 
            $k++; 
        } 
    /* Bug is created here, just this script alone will 
       produce an array of unique types as well as null 
       (more-so towards "") types.
    */
    $tempType = array_unique($type); 
    for($i = 0; $i < sizeOf($type); $i++) 
        for($j = 0; $j < sizeOf($tempType); $j++)  
            if($type[$i] == $tempType[$j]) 
                $tally[$j] = $tally[$j] + 1; 

    array_multisort($tally, SORT_DESC,$tempType); 
    for ($i = 0; $i < sizeOf($tally); $i++) 
        echo $tempType[$i]." has ".$tally[$i]." votes.<br>"; 
?>

Now, I was able to fix this by adding:
<?    
    for($i = 0; $i < sizeOf($tempType); $i++) 
        if($tempType[$i] == NULL) { 
            array_push($tempType,$i); 
            array_pop($tempType); 
        } 
?>
which simply takes the new unique array and pushes null values to the top, then pops them out of the array.
