Date Comparison

[habanero25]

Hello,

 

I'm having trouble writing a program that checks if a date is in between two other dates or not.

 

	
$today = date("d-m-y");
$a = "09-09-06"; //September 9th, 2006
$c = "09-09-09"; //September 9th, 2009

if($a <= $today && $today<$c){
       echo "Wee";
}
else{
echo "Wrong";
}

 

When I try outputting this, it outputs always outputs "Wrong" for some reason, although $today is clearly inbetween $a and $c (Sept.09'06 and Sept.09'09). Am I doing something wrong?

 

Thanks,

Habanero

You're comparing ASCII strings, not dates. To compare dates convert each to a UNIX timestamp and compare them:

<?php
$today = time();
$a = strtotime("2006-09-09"); //September 9th, 2006
$c = strtotime("2009-09-09"); //September 9th, 2009

if($today > $a  && $today<$c)
       echo "Wee";
else
echo "Wrong";
?>
