Agtronic Posted March 24, 2008 Share Posted March 24, 2008 Hey guys and gals, I have a database that contains user profiles. Users' date of birth are stored as unix timestamps, many of which are in the negative. I am able to calculate the age of the users once the timestamp has been pulled from the DB. What I'd like to do is pull users between the ages of (say) 40 and 50 years old. Question : How can I generate a timestamp value based on age so that I can use it in the MySQL query string? Any help would be greatly appreciated! Thank you for your time!

rhodesa Posted March 24, 2008 Share Posted March 24, 2008 These should work: $start = strtotime("-40 years"); $end = strtotime("-50 years"); Link to comment https://forums.phpfreaks.com/topic/97669-how-to-generate-a-timestamp-based-on-age/#findComment-499754 Share on other sites More sharing options...

Barand Posted March 24, 2008 Share Posted March 24, 2008 These should work: $start = strtotime("-40 years"); $end = strtotime("-50 years"); Just being picky but the start date would be the -50 one, as it is earlier Link to comment https://forums.phpfreaks.com/topic/97669-how-to-generate-a-timestamp-based-on-age/#findComment-499862 Share on other sites More sharing options...
