PHP date function date range [duplicate]

Question

Possible Duplicate:
PHP, see if date range is partly within another date range

I have 2 dates, a start date (2011-01-01) and an end date (2011-02-28).

I have a third date that starts on 2010-01-01 and ends on 2012-03-01. This means that this third date falls within the first 2 dates range.

If the third dates start and/or end date is not within the 2 dates then it must be false.

How can I check this using php?

I am using timestamps created by using the strtotime() function. — Wesley

With an if and a few comparisons? What exactly is it that you have a problem with? — Jon

A scenario would be: A project starts on 2011-01-01 and ends on 2011-10-01. I would love to calculate the revenue for 2011-05-01 to 2011-05-31. How can I tell that the project falls within the period? — Wesley

You can do the following:

$startDate = strtotime('2011-01-01');
$endDate = strtotime('2011-02-28');

$intervalStart = strtotime('2011-02-01');
$intervalEnd = strtotime('2012-03-01');


if ($startDate < $intervalStart || $endDate > $intervalEnd) {
    echo 'Not in the interval';
} else {
    echo 'In the interval';
}
