与：

---

为每个列使用一个循环，并根据列数在其中进行计数（注意，我假设它是db中的奇数和偶数列数，而不是在交换编号后的列数，这似乎不是必需的-如果不只是在计数器设置行中交换2和5的话）

---

不要使用
mysql.*
扩展，因为它在PHP 5.5版时已被弃用，在PHP 7.0版时已被删除。使用或替代。是的，我尝试了这个，但不工作。假设奇数列中有2个是，偶数列中有3个是，所以2x2+3x5=19，这意味着你的代码可以工作，但你能解决这个问题吗？看起来你带来了b确认查询中比您感兴趣的列多得多。从使用SELECT*更改为指定要返回的列名。所有表都是email1\u打开的、email2\u打开的、email3\u打开的……等等。我插入了这些，但显示了已编辑的错误，假设第一列（实际具有电子邮件地址）称为contact\u email“选择联系人电子邮件、电子邮件1打开、电子邮件1单击、电子邮件2打开、电子邮件2单击、电子邮件3打开、电子邮件3单击、电子邮件4打开、电子邮件4打开、电子邮件5打开、电子邮件5单击、电子邮件6打开、电子邮件6单击、电子邮件7打开、电子邮件7从报告中单击”；
$yesCount++;
