How to find the last day of the month from date?

Question

How can I get the last day of the month in PHP?

Given:

$a_date = \"2009-11-23\"

I want 2009-11-30; and given

$a_dat         


        

Answer 1

What is wrong - The most elegant for me is using DateTime

I wonder I do not see DateTime::createFromFormat, one-liner

$lastDay = \DateTime::createFromFormat("Y-m-d", "2009-11-23")->format("Y-m-t");
