PHP如果不大于1，打印文本

在下面的代码中，我让服务器检查该人是否在团队中。如果它们是，它显示一些东西，如果它们不是，它显示一些不同的东西。如果这个人在一个团队中(它打印正确的东西)，它就会工作，但如果这个人不在一个团队中，它就不会显示任何东西。任何帮助吗?

            if($_SESSION["username"]){
                $sql2 = mysql_query("SELECT * FROM teams WHERE game='bl2' AND players LIKE '%$sessiongamt%'") or die("Could not allocate information!");
                $num1 = 0;
                while($row = mysql_fetch_assoc($sql2)){
                  $num = ++$num;
                  $amount = mysql_num_rows($sql2);
                  $id = $row["id"];
                  $name = $row["name"];
                  $link = $row["link"];
                  if($amount < 0 || $num1 < 0){
                    print '<hr/>
