Retrieve All Dates Between Two Given Dates in PHP

Determining the sequence of dates within a specified range is a common task in programming. PHP provides several approaches to achieve this, including custom functions and built-in features such as DatePeriod.

Custom Function

A simple custom function could be created to generate an array of dates between two provided inputs:

function getDatesFromRange($startDate, $endDate) {
  $dates = array();
  $currentDate = $startDate;

  while ($currentDate <= $endDate) {
    $dates[] = $currentDate;
    $currentDate = date('Y-m-d', strtotime('+1 day', strtotime($currentDate)));
  }
  return $dates;
}

$dates = getDatesFromRange('2010-10-01', '2010-10-05');
// Output: Array('2010-10-01', '2010-10-02', '2010-10-03', '2010-10-04', '2010-10-05')

DatePeriod Class

PHP's DatePeriod class offers a more versatile solution:

$period = new DatePeriod(
  new DateTime('2010-10-01'),
  new DateInterval('P1D'),
  new DateTime('2010-10-05')
);

$dates = array();
foreach ($period as $key => $value) {
  $dates[] = $value->format('Y-m-d');
}

// Output: Array('2010-10-01', '2010-10-02', '2010-10-03', '2010-10-04', '2010-10-05')

The DatePeriod class provides flexibility in customizing the date intervals and allows for easy iteration through the generated dates.
