Regarding date and time

Hello,

I am looking for some tutorials on how to calculate date / time on php, that utilizes the date object.

For a while, I have been using date(), and strtotime() to come up with dates, but doing calculation and comparing the outputs from those means string comparisson, which is not what I want.

Can you point out some tutorials or links where I can get some samples on using date object ot be able to calculate or comapre dates?

thanks in advance

Hard to tell what you mean but have been using dates in the format of "DD-MM-YYYY" for example? Try using timestamps instead which makes it much easier to compare dates.

hhmm.. this is actually what I considered as my last resort. I don't know if there are any other ways besides time stamps, but I'm open to this idea . Well, what I meant was , I'm using the date() method of php to be able to compu with dates that I compare. Now, since date() returns a string, then that means that the comparing is basically string comparison. What I want to get, is a comparison of dates, as if they are really date variables or date objects.

hhhmm.. are they using the native php date object, or do they have a library of some sort that has dates? I am current using another framework right now. I'm not sure if I wanna transfer it to zend.

There's really a world of information available on date comparisons. Like http://www.phpf1.com/tutorial/php-date-compare.html

Try Googling it.
