php question… how to check if something is between two values?

Question

I know I'm missing something easy here... I've been trying different operators, but haven't been able to figure this out...

How do I go about checking to see if the current date is between two other dates?

So, if I have a from date of 2/2/2010 and a to date of 2/10/2010, how can I return TRUE if the current date (2/4/2010) falls between those two dates?

Answer 1

To do a comparison like this you need to do separate comparisons. If $d is the date you want to compare, $d1 is the earlier date, and $d2 is the later date, it would be something like:

if ((strtotime($d) > strtotime($d1)) and (strtotime($d) < strtotime($d2))) {
    return true;
} else {
    return false;
}

Answer 2

Off the top of my head, I don't know of a date comparison operator in PHP, but I would use strtotime() on all three dates, then do simple mathematical comparisons.

<?php

$early_date = strtotime("02/02/2010");
$date = strtotime("02/04/2010");
$late_date = strtotime("02/10/2010");

if (($early_date < $date) && ($date < $late_date)) {
  echo "true";
}

returns true.

Answer 3

If past date one and before date two, then it's between them.

Answer 4

the googles told me

if ( strtotime($date) > strtotime('22/09/2008') && strtotime($date) < strtotime('28/09/2008'))

wouldn't this work ?

 ( ($lowerlimitdate <= $checkingdate) && ($checkingdate <= $upperlimitdate))
