How to check if a date is in a given range of day+month? [duplicate]

Answer 1

You can use this small function:

<?php
    $s_date = strtotime("2009-03-01 12:00");
    $e_date = strtotime("2009-03-03 14:00");
    $date = strtotime("2009-03-02 13:00");
    if($date > $s_date && $date < $e_date)
        print "Date is between start and end";
    else
        print "Date is outside start and end";
?>

function isDateBetween($dt_start, $dt_check, $dt_end){
    if(strtotime($dt_check) > strtotime($dt_start) && strtotime($dt_check) < strtotime($dt_end))
        return true;
    return false;
}
isDateBetween("2004-01-01", "2004-01-02", "2004-01-03")

Answer 2

Date values in PHP are expressed as UNIX timestamps and they represent the number of seconds passed since January 1st 1970.

You can use mktime function to create the dates ( http://php.net/manual/en/function.mktime.php ). Once you have them as numbers, you can easily compare them.

$interval_start = mktime(0, 0, 0, 1, 0, 2000);
$interval_end = mktime(0, 0, 0, 1, 0, 2010);
$my_date = mktime(0, 0, 0, 1, 0, 2004);
if($my_date > $interval_start && $my_date < $interval_end) {
    // in the interval
} else {
    // not in the interval
}
