From the code shown, it is incomplete?

if($string{0}!='"'){ //<--No Closing Brace ***
	$pieces=explode(" ",$string);
    for($i=0;$i<(count($pieces)-1);$i++){ //<--No Closing Brace ***
    	if ($adi) {
            $SQL="SELECT baslik FROM konular WHERE baslik like '%$pieces[$i]%' and statu=''";
        }
        $sorgu=mysql_query($SQL) ;
        if (!$sorgu){ //<--No Closing Brace ***
