finding difference between dates

[j_miguel_y]

I want to be able to find the difference between 2 dates because I am starting a website in which offers a 30 day trial. What is the easiest way of coming around this?

Any examples?

Search the forum, look in the PHP manual at php.net for date(), time(), strtotime(), strtftime() and mktime(). Search the mysql manual at mysql.com for date_format() syntax...

That should keep you busy for a while... This topic has been beat to death the past week or so on these boards... All you gotta do is look.
