This question already has an answer here:
I'd like to take a number of hours imputed in a text box and get a timestamp back so I can create a countdown timer.
The countdown is fine so ignore how that is done etc. But whats the best way to get a timestamp '48' hours from now. For example user has entered 48?
</div>
$hours = 48;
$timestamp = (new DateTime())->modify("+{$hours} hours")->format('U');
You can create a timestamp like this:
<?php
strtotime(date('d-m-Y H:i:s') . "+ 48 hours");
?>
Your looking for strtotime. For example, you can just use strtotime('+48 hours'), and it will return a unix timestamp for that time.
