How do I go about checking to see if the current date is between two other dates?开发者_Python百科
I've been trying different operators, but haven't been able to figure this out.
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?
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.
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($d2))) {
return true;
} else {
return false;
}
If past date one and before date two, then it's between them.
the googles told me
if ( strtotime($date) > strtotime('22/09/2008') && strtotime($date) < strtotime('28/09/2008'))

wouldn't this work ?
( ($lowerlimitdate <= $checkingdate) && ($checkingdate <= $upperlimitdate))
