IF Statement Date comparison

Hello All, im looking for a simple date comparison if statement. I searched google and only found one result worthwhile and for whatever reason I couldnt seem to get it to work, they were using strtotime()..

Anyway, just looking for a simple setup like:

if ($ThisDate is in the past) {
echo "sorry, this date has arleady passed";
} else {
echo "Sign Up Now!";
}

 

Read the following article, it will surely help you

EDIT: A few seconds too late...

strtotime() is probably the easiest way to do it. In which format is your date?

 

I got it, thanks guys, it took a little modification to the code provided by that webpage but it works awesome now, thanks.
