PHP strtotime +1 month behaviour

Question

I know about the unwanted behaviour of PHP\'s function

strtotime

For example, when adding a month (+1

Answer 1

what you need is to tell PHP to be smarter

$the_date = strtotime('31.01.2011');
echo date('r', strtotime('last day of next month', $the_date));

$the_date = strtotime('31.03.2011');
echo date('r', strtotime('last day of next month', $the_date));

assuming you are only interesting on the last day of next month
