[ciapug] Dates question

[Chris Hettinger]

Working with dates still challenges me

$date1 = date('Y-m-d H:i:s');  // current date
$date2 = X;

I need to know if $date2 is 30 or more days in the future from the 
current date.

If $date2 >= $date1 by 30 days
   echo 'date2 is more than 30 days in the future';
else
   echo 'date2 within 30 days of date1';


^^--- how do I do this comparison?
