只有PHP strtotime的未来日期（）

Question

PHP's strtotime() uses the current year by default. How to get only future dates?

echo date('l d. M Y', strtotime('first sunday of april')); // Sunday 03. Apr 2016

I can't manage to get the next first Sunday of April. The date must not be in the past and it must be always relative (no 2017 or 2018 hardcoded).

echo date('l d. M Y', strtotime('first sunday of next april')); // fails

echo date('l d. M Y', strtotime('first sunday of april next year')); // wrong from January until that Sunday in April

I think I could do it in multiple steps or create a function to check, if current time is before/after the first Sunday and insert a 'next year' at the end.

But I was wondering if there is a simple solution with strtotime()

Answer 1

I dont think this is particularly elegant, but it works, and I hope it is what you were looking for?

echo date('l d. M Y', strtotime('first sunday of april', strtotime('first day of next year')));

However this seems like a much better, maintainable, readable solution

$d = new DateTime();
$d->modify( 'first day of next year');
echo $d->format('l d. M Y') . PHP_EOL;
$d->modify( 'first sunday of april');
echo $d->format('l d. M Y') . PHP_EOL;

Which gives

Tuesday 01. Aug 2017
Sunday 02. Apr 2017

The echo of the year change date, you would not need to do, its there just to prove that the year changed
