Question

Is there a way to find out if a date falls within 7 days of the current date using PHP? If there is, would it also be possible to figure out how many days away that date is?

Answer 1

$date = strtotime('2010-11-28');

if (strtotime('-7 days') < $date && $date < strtotime('+7 days')) {
    // yup
}

$difference = abs($date - time()) / 60 / 60 / 24;

Could be refined a bit if you care about edge cases, whole days and daylight-savings/leap seconds issues, but this should hopefully give you the right idea. Of course the Date class should be the preferred method to handle this, but it’s only available in PHP 5.3+.
