PHP: How to determine Unix Timestamp of midnight tomorrow?

Question

I have the following code to determine the unix timestamp of midnight tomorrow. It seems pretty hacky to me and I wondered if anyone had a more elegant solution.

date("U", strtotime(date("Y-m-d 00:00:00", strtotime("tomorrow"))));

Answer 1

This should be enough:

<?php
$t = strtotime('tomorrow');

You can also set a time:

<?php
$t = strtotime('tomorrow 14:55');

Please note that, as other date features in PHP, it will use the default time zone unless asked otherwise:

date_default_timezone_set('Asia/Tokyo');
$t = strtotime('tomorrow');
var_dump($t, date('r', $t));

date_default_timezone_set('Europe/Madrid');
$t = strtotime('tomorrow');
var_dump($t, date('r', $t));

date_default_timezone_set('Europe/Madrid');
// Generate midnight in New York, display equivalent Madrid time
$t = strtotime('tomorrow America/New_York');
var_dump($t, date('r', $t));
