AyKay47 Posted April 4, 2012 Share Posted April 4, 2012 Are you using a date/datetime field to store the date in your db table? Link to comment https://forums.phpfreaks.com/topic/260335-mysql-select-datas-after-time-interval/#findComment-1334304 Share on other sites More sharing options...

dcro2 Posted April 9, 2012 Share Posted April 9, 2012 You can't really schedule queries to happen with just php or mysql. Use cron. http://www.htmlcenter.com/blog/running-php-scripts-with-cron/ */15 8-20 * * * php /path/to/php/file.php It all depends on what host you're on, if you have cPanel, etc. Link to comment https://forums.phpfreaks.com/topic/260335-mysql-select-datas-after-time-interval/#findComment-1335629 Share on other sites More sharing options...
AyKay47 Posted April 9, 2012 Share Posted April 9, 2012 In your query you will compare the timestamp field to NOW() Link to comment https://forums.phpfreaks.com/topic/260335-mysql-select-datas-after-time-interval/#findComment-1335630 Share on other sites More sharing options...
