Using php strtotime function difference between dates:
1 2 3 4 | //number of seconds between two dates$s = strtotime("2012-02-21 00:00:00") - strtotime("2011-02-21 00:00:00");//how many days between two datesecho $s/60/60/24; |
Another way to set date with mktime function:
1 2 3 4 | //number of seconds between two dates$s = mktime(0, 0, 0, 21, 02, 2012) - mktime(0, 0, 0, 21, 02, 2011);//how many days between two datesecho $s/60/60/24; |
Before PHP 5.1.0 negative timestamps were not supported. Under any known version of Windows date could be from 1970 to 2038 years.
And using MySQL difference between dates:
1 | SELECT TO_DAYS('2012-02-21 00:00:00') - TO_DAYS('2011-02-21 00:00:00'); |
