Tech Date() countdown until last Sunday of the month?

[Publisher Bucks]

I have the following code:

$dt_end = new DateTime('June 26, 2022');
$remain = $dt_end->diff(new DateTime());
echo $remain->d . ' days and ' . $remain->h . ' hours';

How would I go about changing it so that each month, it will display the days until the last Sunday of the month without having to put the date in the code?

I've searched a few different places and can't find anything specific to what I need

Hopefully that makes sense?

TIA for any help you can offer.

Did you try 'last Sunday of the month'? PHP surprisingly can parse a lot of these things and do the heavy lifting for you

Google is your friend.

Like baodb said, you can use the string "last sunday of month year" in the date function to get the date of the last sunday.

date('Y-m-d', strtotime('last sunday of ' . $month . ' ' . $year)

Here is an example they have looping through and getting the last sunday of every month.

// Created with PHP 7.0

function printLastSundayOfAllMonth($year)
{
$months = array(
'January', 'February', 'March', 'April', 'June', 'July',
'August', 'September', 'October', 'November', 'December');

foreach ($months as $month) {
echo $month . ': ' . date('Y-m-d', strtotime('last sunday of ' . $month . ' ' . $year)) . "\n";
}
}

printLastSundayOfAllMonth($argv[1]);

I swear I searched for this in Google and Sitepoint and nothing came up :/

Thank you both.
