How do you list months between two dates in PHP?

Listing Months Between Two Dates

Enumerating the months between two arbitrary dates may seem like a simple task, but it becomes more intricate when dealing with edge cases. To effectively address this problem, we can leverage various programming techniques.

Approach 1: Using PHP Built-In Functions

For PHP versions 5.3 and above, we can utilize the DateTime and DatePeriod classes.

<code class="php">$start    = new DateTime('2010-12-02');
$start->modify('first day of this month');
$end      = new DateTime('2012-05-06');
$end->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period   = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
    echo $dt->format("Y-m") . "<br>\n";
}</code>

Approach 2: Using Pure PHP (PHP 5.4 or Newer)

If using PHP 5.4 or later, we can streamline the code as follows:

<code class="php">$start    = (new DateTime('2010-12-02'))->modify('first day of this month');
$end      = (new DateTime('2012-05-06'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period   = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
    echo $dt->format("Y-m") . "<br>\n";
}</code>

Considerations:

• It's crucial to modify the start and end dates to the first of the month to avoid skipping February.
• These approaches handle months correctly, even for leap years.
