PHP Day iterator

Question

I'm able to show days from current date to next 3 months with this code:

$begin = new DateTime();
$end = new DateTime(date('Y-m-d', strtotime('+3 months', strtotime(date("d-m-Y")))));
$interval = DateInterval::createFromDateString('1 day');
$days = new DatePeriod($begin, $interval, $end);

foreach ( $days as $day ) {
    ...
}

I feel the code can be shortened especially for $end. Could you help?

Oh, I also want to get previous 3 months. I changed '+3 months' to '-3 months'but no luck. Any ideas?

$begin    = new DateTime();
$end      = new DateTime('+ 3 months');
$interval = DateInterval::createFromDateString('1 day');
$days     = new DatePeriod($begin, $interval, $end);
foreach ( $days as $day ) {
    var_dump($day);
}

$begin    = new DateTime('- 3 months'); // '3 months ago' should also work
$end      = new DateTime();
$interval = DateInterval::createFromDateString('1 day');
$days     = new DatePeriod($begin, $interval, $end);
foreach ( $days as $day ) {
    var_dump($day);
}

Stefan, how if i want to get 3 months ago from certain date (not current)? – Jeaf Gilbert Nov 29 '10 at 03:44
`$begin = new DateTime('2010-01-01 12:00:00');` and `$begin->modify('-3 months');` – Stefan Gehrig Nov 29 '10 at 08:02
`$begin = new DateTime('2010-01-01 12:00:00 - 3 months');` will also work (at least on PHP 5.3.3) – Stefan Gehrig Nov 29 '10 at 08:05

For your first question, you can directly write

$end = new DateTime('+3 months');

To go back 3 months, use3 months ago instead of -3 months.

Turns out my code was wrong to show previous, -3 months should work as well. Thanks. – Jeaf Gilbert Nov 26 '10 at 08:40
