我轉換... TNX反正:)

$new_mail = mysqli_fetch_array(mysqli_query($db, "SELECT COUNT(*) FROM `mail` LEFT JOIN `contact` ON `mail`.`user_id`=`contact`.`from_id` AND `contact`.`user_id`='$user_id' WHERE `mail`.`from_id`='$user_id' AND `mail`.`obrisano`!='$user_id' AND `contact`.`ban`!='1'")); 

@ryan我只是想給MySQL查詢mysqli的轉換，但TNX :)
