Select rows from MySQL table where PHP timestamp is older than X

Question

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.

My user_regdate is a timestam

Answer 1

php's time() function outputs a unix timestamp (the number of seconds since January 1 1970). MySQL's now() function outputs a formatted date (like 2011-6-9 12:45:34)... so I don't think you can compare them like that.

Try using the unix timestamp, minus 7 days, instead of now() in your query:

 $7_days_ago = time() - (7 * 24 * 60 * 60);
 mysql_query("select * from users WHERE user_regdate <" . $7_days_ago . " AND approved='0' order by id;");
