Find the Last Day of the Month With PHP

Google - last day of month php - and you'll get over 15,000,000 results. It's amazing how many people have searched for this & how many roundabout ways there are to accomplish what should be a simple task.

Here is the simplest way (that I know of) to get the last day of the month using PHP.

Get last day of the current month

$lastday = date('t',strtotime('today'));

Get last day of next month

$lastday = date('t',strtotime('next month'));

Get last day of any other month
Enter any month/day/year to get the last day of that month

$lastday = date('t',strtotime('3/1/2009'));

If you want to display the last day of this month on your website, do the following:

<?php
echo date('t',strtotime('today'));
?>

I needed to find out the last day of a user specified month from a dropdown, and I searched and found ridiculously long complicated functions but knew there must be a simple php way of doing it and luckily I came across this blog and from it created the following

$intLastDayInChosenMonth = date('t', strtotime($dteYear.'/'.$dteMonthID.'/01'));

Thankyou!!!

$lastdayFeb = date('t',strtotime('2/2/2039')); // 31!
