Evet derler hocam, çünkü işte bu kadar basit:

<?
$y = 0;
$x = 0;
$numbers[0] = 0;
while ($y < 10)
{
        $yazar= mysql_fetch_array( mysql_query("SELECT jos_content.id, jos_content.title, jos_categories.image, jos_categories.name,"
        . "\n jos_content.catid, jos_content.sectionid, jos_content.created"
        . "\n FROM jos_content"
        . "\n LEFT JOIN jos_categories ON jos_content.catid = jos_categories.id"
        . "\n LEFT JOIN jos_sections ON jos_content.sectionid = jos_sections.id"
        . "\n WHERE jos_content.sectionid='4'"
        . "\n ORDER BY jos_content.created"
        . "\n DESC LIMIT $x,1"));
	$ranvar = $yazar['catid'];
	if ($nuser == NULL) { $y = 11; }
	elseif (in_array($ranvar, $numbers)) $x++;
        else
	{
		$numbers[$x] = $ranvar;
?>

Bunda kendini sıkacak ne var anlamadım, yapamıyorsak yapamıyoruz deriz.
