请教一个这个法中的两个字段UPDATA的顺序

下面这个方法有一个更新数据库的操作，想请问大神们        下面这两个变量里面的值是更新在if($shijiancha){****}这个判断前面还是后面？因为数据库里面保存的数据是没有经过if($shijiancha){****}这个判断里面操作的，如果想保存在操作之后要怎么写呢？新手PHP请大家多多指教，谢谢！
$content = addslashes($tocode->go_content);
    $counttime = $tocode->count_time;

update 表名 set 字段1=-5 ,字段2=100 where 字段3='0101'

前面的and 换成逗号，最后那个0101要用单引号引起来(前面几位都没有发现啊)。
