What is the best way to find out if 2 dates are in same month in PHP?

Question

I have 2 dates that are unix time stamps and I would have to figure out if the dates are in same month. For example if I have 1393624800 = 02 / 28 / 14 and 1391472000 = 2 / 4 / 2014. I figured I could convert the unix time stamps to format like 28-02-2014 and extract the month, but I feel like its kinda dirty method. What is the best way to do this?

EDIT: Sry I forgot. Also have to make sure its the same year.

Solution 1

I would suggest using the DateTime class

$date1 = new DateTime();
$date1->setTimestamp($timestamp1);

$date2 = new DateTime();
$date2->setTimestamp($timestamp2);

if ($date1->format('Y-m') === $date2->format('Y-m')) {
    // year and month match
}

I would highly suggest to anyone learning PHP to learn the DateTime and related classes. They are much more powerful than the basic date functions.

Solution 2

if (date("F Y", $date1) == date("F Y", $date2))

see http://au2.php.net/manual/en/function.date.php

that makes sure they are in the same month and year, otherwise do something like:

if (date("n", $date1) == date("n", $date2))

Solution 3

Probably this:

$first = date("m", $timestamp);
$second = date("m", $timestamp2);

if($first == $second) {
   // they are in same month
}
else {
   // they aren't
}
