Return the year from a future month

[htcilt]

I would like to echo the year for next september e.g. today it would return 2010, on 01/09/2010 it would return 2011.

Does anyone know how I can produce this?

Can you be more specific on what you're looking for? Today is Feb 16, 2010, and you say that this should be year 2010, but that sept 1 2010 should be 2011?

Maybe something like this:

PHP Code:

echo date('Y',strtotime('01/09/2011')); 


or even something like this:

PHP Code:

echo substr('01/09/2011',strrpos('01/09/2011','/')+1); 


would be suitable for you ?

I am sorry if my guess on what you need is wrong. In this case as Fou-Lu said could you explain the problem a little bit more in detail please ?

Agreed, your question makes little sense. Maybe this is what you're trying to accomplish?

PHP Code:

$next_year = date( 'Y', strtotime( '+1 year' ) ); 


Edit: Oh, I think I get you... as of today, the next September would fall in 2010, but in September 2010, the next September would fall in 2011.

Apologies. I'll try explain a bit better.

I need show to the year for the the next 1st September dynamically, i.e. the function returns the year without any date string entered.

For example

Today (16/02/2010) would return 2010
but from 01/09/2010 the next 1st September would be in the year 2011
on 20/04/2011 the next 1st September would be in the year 2011

2011 would be returned right up until 1st September 2011, when it would then return 2012.

I need something that will run happily without any manual changing of date string.

Let me know if you need any more information or if I'm still not explaining clearly

Function name could use some work

PHP Code:

function next_year_by_month( $month = NULL )
{
    // no month specified... use current, which will always return next year
    if ( NULL === $month )
    {
        return 1 + date( 'Y' );
    }
    // build a timestamp based on the selected month
    $mktime = mktime( 0, 0, 0, ( int ) $month );
    // grab the associated year
    $year = ( int ) date( 'Y', $mktime );
    // if month is current or in the past, reflect the next year
    if ( date( 'Y-m' ) >= date( 'Y-m', $mktime ) )
    {
        $year++;
    }
    // send it on it's way
    return $year;
} 


PHP Code:

// Today is Feb 16, 2010 (2010/02/16)

// Current month
echo next_year_by_month(); // 2011

// January
echo next_year_by_month( 1 ); // 2011

// February
echo next_year_by_month( 2 ); // 2011

// March
echo next_year_by_month( 3 ); // 2010

Thanks kbluhm,

I would have been here until 1st September trying to figure it out!

[Fou-Lu]

Gotcha.
Avoiding some of the newer date features:

PHP Code:

function pivotYear($iCurrent, $pMonth, $pDay)
{
    $iYear = (int)date("Y", $iCurrent);
    if (!checkdate($pMonth, $pDay, $iYear))
    {
        trigger_error('Invalid pivot month/day provided!');
    }

    if (date("n", $iCurrent) > $pMonth || (date("n", $iCurrent) == $pMonth && date("j", $iCurrent) >= $pDay))
    {
        ++$iYear;
    }
    return $iYear;
}

// Used:
print pivotYear(time(), 9, 1); 


No idea if it works, I'm at work so I can't test it. Works alright in my head though

Edit:
Bah, way too slow today >.<

Edit:
OHHHHHHHHH! I guess I didn't getcha lol.
Yes, use kblums, I completely ignored the fact that this should cover past months as well (as in, its not sensitive to the year change). I would expect that mine should return 2010 if provided with a time created in january, instead of 2011 as it should.
