First we need to convert the two dates to UNIX Timestamps using the PHP function strtotime Then we can compare the two dates in anyway we wish, in the example below I’m checking that the first date is older than the second date $date1 = '1999-10-11'; $date2 = '2010-10-11'; $firstDate = strtotime($date1); $secondDate = strtotime($date2); if($firstDate < $secondDate){ echo 'First date is older'; }else{ echo 'Second date is older'; }
In the example you’ll find a handy PHP function that will do the conversion. <?php $DATETIME = '2010-04-22 19:54:38'; echo convertDateTime($DATETIME); /* * This function converts a mysql datetime to a unix timestamp * The format should be "YYYY-MM-DD HH:MM:SS" * * @param $datetime string Contains the DATETIME value * @return UNIX TIMESTAMP */ function convertDateTime($datetime) { list($date, $time) = explode(' ', $datetime); list($year, $month, $day) = explode('-', $date); list($hours, $minutes, $seconds) = explode(':', $time); $UnixTimestamp = mktime($hours, $minutes, $seconds, $month, $day, $year); return $UnixTimestamp; } ?> First we divide the date from the time and then break up the date into year, month and day variables. After that we break the time up into hour, minute and second and then we create a Unix Timestamp using the mktime PHP function.
