datetime - 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 is 2010-11-16 12:25:00 PM and want to check if the time is between 2010-11-16 09:00:00 AM to 06:00:00 PM. In the above case its true and if the time is not in between the range it should return false. Is there any inbuild PHP function to check this or we will have to write a new function??

Answer 1

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
}
