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 <p>This function returns a boolean value indicating whether the user's date falls within the specified range.</p><p>By converting the dates to timestamps, we ensure compatibility with PHP's date comparison and arithmetic operations, simplifying the process of verifying date ranges.</p>
