Determine if a given date is on or between two other dates.

[Arc]

I can't seem to find a function that will tell me if a given date is on or between two other dates.

For instance, $isBetween = DateBetween($theDate,$fromDate,$toDate);

Where theDate is the given date, fromDate is the earliest date and toDate is the latest date.

if toDate = aug-2-2007 and fromDate = aug-1-2007 and toDate= aug-15-2007 the function would return true.

Is there a built in PHP function that does this kind of thing? If not, does anyone know how to go about doing it?

Thanks!🙂

no such function

but this is like using 2 numbers and see if a third number is between

As long as: $a < $b
this simple test will work

<?php

function test( $date, $a, $b ){

if( $date >= $a  &&  $date <= $b ){
    return true;
}else{
    return false;
}

} // end func

$date = 7;
$btween = test( $date, 3, 10 );

if($btween)
    echo 'between';
else
    echo 'not between';

?>

Yah, I thought of that, but wasn't sure it would be accurate with dates. I'll give it a shot.

Thanks!

You can use [man]mktime/man or [man]strtodate/man to convert a date into Unix timestamps which are very easy to compare (they're simply integers).
