从MySQL表中选择PHP时间戳早于X的行 [英] Select rows from MySQL table where PHP timestamp is older than X

问题描述

我有一个用户表，需要在此表中批准用户，我想显示未批准并在7天前注册的用户.

I have a user table, where users need to be approved, i want to show users who are not approved and is registered more than 7 days ago.

我的user_regdate是使用php time()函数创建的时间戳.

My user_regdate is a timestamp created with php time() function.

这是我尝试的方法，它不起作用:

This is what i try, it does not works:

mysql_query("select * from users WHERE user_regdate < now() - interval 7 day AND approved='0' order by id;");

谢谢

推荐答案

PHP的timstamp是一个简单的整数，而MySQL的now()返回日期时间值.这很可能会解决该查询:

PHP's timstamps are a simple integer, whereas MySQL's now() returns a datetime value. Most likely this will fix up the query:

SELECT ... WHERE user_regdate < unix_timestamp(now() - interval 7 day)) ...

基本上，没有unix_timstamp()调用，您正在比较苹果和橘子.

Basically, without the unix_timstamp() call, you're comparing apples and oranges.
