How Can I Check if a Date Falls Within a Specific Range in PHP?

Inspecting Date Ranges with PHP

Determining whether a specified date falls within a predefined range is a common task in programming. Let's consider a scenario where you have a start date ($start_date), an end date ($end_date), and a date provided by a user ($date_from_user). The goal is to ascertain if the user's date lies within the specified range.

Converting the dates to timestamps using the strtotime() function proves advantageous:

$start_date = '2009-06-17';
$end_date = '2009-09-05';
$date_from_user = '2009-08-28';

You can leverage the check_in_range() function to perform the verification:

function check_in_range($start_date, $end_date, $date_from_user)
{
  // Convert to timestamps
  $start_ts = strtotime($start_date);
  $end_ts = strtotime($end_date);
  $user_ts = strtotime($date_from_user);

  // Check that user date is between start & end
  return (($user_ts >= $start_ts) && ($user_ts <= $end_ts));
}

This function returns a boolean value indicating whether the user's date falls within the specified range.

By converting the dates to timestamps, we ensure compatibility with PHP's date comparison and arithmetic operations, simplifying the process of verifying date ranges.
