Question

HI, i have a couple of posts in my MySql database server, one of the info content in each post is the date and time in the format datetime (Ex. 2010-11-26 21:55:09) when the post was made.

So, i want to retrive the actual date and time from the SQL server with the function NOW() and calculates how many seconds or minutes or hours or days ago was post the info.

I dont know how to create this php script but i know that for sure is allready made, so thanks for any help.

As billythekid said, you can use the date_diff() function if you are using PHP5.3+, if you are not then there are various methods. As shown by other posters. The quickest method in MySQL if you want to know the time split in to the “hours:mins:secs” hierarchy is to use the TIMEDIFF() function.

SELECT TIMEDIFF(NOW(), '2010-11-26 12:00:00');

If you want it as seconds, use the unix timestamp features in MySQL or in PHP, you can convert MySQL dates to PHP quickly using strtotime().
