Date manipulation

[dannybrazil]

Hello,

 

I have a code that adds 1 month to a specific date every month.

$newdate = strtotime ( '+1 month' , strtotime ( $b_date ) ) ;
$new_date = date ( 'Y-m-d' , $newdate );

 

the thing is some month of the year do not contain the SAME amount of days.

 

For example:

 

If the date was 2011-01-31

 

+ 1 month

 

=

 

03-03-2011

 

Is there any way to add a month (+1 month) but make it consider the calendar.

 

lets say that I had 2011-01-31 --> +1 month == 2011-28-02 (the last day of the next month if there is NO similar days in month

 

Thanks
