How Can I Efficiently Verify if a Date Falls Within a Given Range in PHP?

Verifying Date Ranges

In programming, situations arise where you need to determine if a specified date lies within a predefined range. Utilizing timestamps as integers proves to be an effective solution for this task.

To illustrate this, consider the following scenario:

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

By converting these dates to timestamps using the strtotime() function, we can easily perform a range check:

function check_in_range($start_date, $end_date, $date_from_user)
{
  // Convert to timestamp
  $start_ts = strtotime($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 will return true if the user-provided date falls within the specified range and false otherwise. By utilizing timestamps, we can efficiently compare dates without relying on string comparisons, ensuring accurate and reliable results.</p>
