I'd like to check if to Zend_Date datetimes are on the same day. How can I do that?

$date1 = new Zend_Date('2011-11-14 10:45:00');
$date2 = new Zend_Date('2011-11-14 19:15:00');

  • Same day as in, Monday, Tuesday etc... or the same date, excluding time? I any case, Zend has a compare method. http://framework.zend.com/manual/en/zend.date.basic.html, you can extract whatever format you want. – Matt Nov 14 '11 at 11:11
  • Sorry for the possible confusion, I mean the same date, excluding time, *not* the same day of week! – BenMorel Nov 14 '11 at 11:14
  • kind of what i figured from the example, just making sure. Also heres a list of constants you might need. http://framework.zend.com/manual/en/zend.date.constants.html – Matt Nov 14 '11 at 11:17

$date1 = new Zend_Date('2011-11-14 10:45:00');
$date2 = new Zend_Date('2011-11-14 19:15:00');
if ($date1->compareDay($date2) === 0) {
    echo 'same day';
}

Also see the chapter on Comparing Dates with Zend Date

On a sidenote, I strongly encourage you to verify if you have the need for Zend_Date. Do not use it just because it is part of ZF. Most of what Zend_Date does can be achieved faster and more comfortably with native DateTime as well:

$date1 = new DateTime('2011-11-14 10:45:00');
$date2 = new DateTime('2011-11-14 19:15:00');
if ($date1->diff($date2)->days === 0) {
    echo 'same day';
}

EDIT after comments
If you want to compare whether it's the same date just do 

$date1->compareDate($date2)

  • Exactly what I was looking for (`compare()` and `equals()` can only -AFAIK- compare the day of the month, not the full date part). Thanks! – BenMorel Nov 14 '11 at 11:21
  • Sorry, I had to de-tag your answer as accepted, after noticing that it actually only compares the day, not the date (+ month + year). Same day next month returned true as well. – BenMorel Dec 19 '11 at 17:36

    @Benjamin errrm, of course it does because you asked for the **same day**, not the **same date**. if you want the same date just do `$date1->compareDate($date2)` – Gordon Dec 19 '11 at 17:46

    My god, such an obvious method name, thanks for showing me the light! There was confusion about *day* vs *date* at the time I wrote my question, clarified in the comments. Your answer is back to Accepted ;-) – BenMorel Dec 19 '11 at 17:50
