数据库的模式是什么？另外，是否有一个原因，你没有推迟到数据库的处理？（毕竟，您可以修改第一个查询以仅返回那些即将到期的行，以便您不必执行第二个查询来执行日期比较） – 2012-01-31 08:50:32

您的第二个选择不需要。将一列添加到您现在将返回的第一条语句（） - expired_on – alfasin 2012-01-31 08:56:12

感谢您的回复 – tamildinesh 2012-01-31 09:23:04

尝试这样的事情...

PHP: $now = date('Y-m-d', strtotime('now'));

SQL: WHERE $now >= DATE_FORMAT(expires, "%Y-%m-%d")

写你的第二个选择查询如下

SELECT DATEDIFF($exdate, CURRENT_DATE) as diff;

而且，不需要编写单独的选择查询你可以在第一查询本身相同之列

SELECT column1, column2, column3, DATEDIFF(expired_on, CURRENT_DATE) as diff 
FROM supplier_product_det

您可能需要改变位置expired_on和CURRENT_DATE得到正确的差异值
