## Difference Between Two Dates?

Jun 1, 2009

I would like to know how to achieve this. I want to know the difference between two dates in months, how much days left over, and how much hours left over. I do not need days or hours equivalent to the months remaining. The problem is I also want it to consider February's less than 30 days and 29 days in leap year. I spend my entire week trying to figure out how to do it.

In the end I want values in variable months_left, days_left, and hours_left. I tried modifying several date deference scripts but I couldn't get them to work as intended.

Basically, the search.php file I'm passing the variables to need to be in this format:

Code:
search.php?month=(arrival month digit)&day=(arrival day digit)&year=(arrival year, 4 digits)&days_count=(number of nights)(...plus some other variables...)
