PHP function to check time between the given range?

Question

I am using PHP\'s Date functions in my project and want to check weather a given date-time lies between the given range of date-time.i.e for example if the current date-time

Answer 1

The function to check if date/time is within the range:

function check_date_is_within_range($start_date, $end_date, $todays_date)
{

  $start_timestamp = strtotime($start_date);
  $end_timestamp = strtotime($end_date);
  $today_timestamp = strtotime($todays_date);

  return (($today_timestamp >= $start_timestamp) && ($today_timestamp <= $end_timestamp));

}

Call function with parameters start date/time, end date/time, today's date/time. Below parameters gets function to check if today's date/time is between 10am on the 26th of June 2012 and noon on that same day.

if(check_date_is_within_range('2012-06-26 10:00:00', '2012-06-26 12:00:00', date("Y-m-d G:i:s"))){
    echo 'In range';
} else {
    echo 'Not in range';
}

Answer 2

Simply use strtotime to convert the two times into unix timestamps:

A sample function could look like:

function dateIsBetween($from, $to, $date = 'now') {
    $date = is_int($date) ? $date : strtotime($date); // convert non timestamps
    $from = is_int($from) ? $from : strtotime($from); // ..
    $to = is_int($to) ? $to : strtotime($to);         // ..
    return ($date > $from) && ($date < $to); // extra parens for clarity
}
