PHP: Date larger than current date

I have my dates in this format: dd-mm-yyyy

Now according to php, 28-06-2011 is bigger than 01-11-2011

$today = date('d-m-Y', time());

if("28-06-2011" > $today ){
     echo "This returns true";
}

How can i make this work properly?

Answer 1

You can’t compare dates like that. They’re two strings. PHP will try to interpret them as numbers (taking the first two digits and then failing because of the -) and compare those. Turns out this is not correct. YYYY-MM-DD type strings can indeed be compared using > and <.

So refer to Col. Shrapnel’s answer and change your date format – it makes sense anyway. If you can’t do that (because it’s a user-input date or whatever), you can create two DateTime objects which, thanks to PHP 5 magic, you can also compare like this:

$date1 = new DateTime('2000-01-01');
$date2 = new DateTime('2001-01-01');

if ($date1 > $date2)... // this works
