getdate this and next month etc.

[tristeve]

Just looked at this old post on the forum [webmasterworld.com...]
and am using some of the ideas to try to retrieve a list of this month, next month, etc.
My code at the moment (which was working yesterday) is:

<?php
$month = date ("F");
echo ($month);
$next = date ("F", strtotime ("+1 month"));
echo ($next);
$next2 = date ("F", strtotime ("+2 month"));
echo ($next2);
$next3 = date ("F", strtotime ("+3 month"));
echo ($next3);
$next4 = date ("F", strtotime ("+4 month"));
echo ($next4);
$next5 = date ("F", strtotime ("+5 month"));
echo ($next5);
$next6 = date ("F", strtotime ("+6 month"));
echo ($next6);
$next7 = date ("F", strtotime ("+7 month"));
echo ($next7);
$next8 = date ("F", strtotime ("+8 month"));
echo ($next8);
$next9 = date ("F", strtotime ("+9 month"));
echo ($next9);
$next10 = date ("F", strtotime ("+10 month"));
echo ($next10);
$next11 = date ("F", strtotime ("+11 month"));
echo ($next11);
?>

Today however, my list of months is output as follows:
March, May, May, July, July, August, October, October, December, December, January, March.

I know it's not pretty, but can anyone see where I'm going wrong.
Yesterday the output was March, April, May, June, July, August, September, October, November, December, January, February

Thanks in advance,
Steve

Welcome to WebmasterWorld, tristeve!

The reason this is happening is that one month from today, March 31, is April 31. But since there is no April 31 this year¹ the date is determined to be May 1. And you are only returning the

month

portion of the date. Make sense?

¹you must take into account leap years, if we were using February, for example

Makes perfect sense. Thanks Coopster for the quick response.

Sure. Here are a couple of code snippets to help you get the next month as you would like. I included links to the PHP manual that describes the functions being used.

print 'The months, starting with this month:<br />'; 
for ($i = 0; $i < 12; $i++) { 
 print date [php.net]("F", mktime [php.net](0, 0, 0, date('m')+$i, 1, date('Y'))); 
 print '<br />'; 
} 
print 'The months, starting with next month:<br />'; 
for ($i = 0; $i < 12; $i++) { 
 print date('F', strtotime [php.net]("+$i month", strtotime('first day'))); 
 print '<br />'; 
}
