Backward-counting day display in php

Question

I would like to show the number of days missing for a specific date. In other words, I want to display something like:

X days to go for the great event

using PHP and the server time.

Answer 1

<?php

    $event_date = '2010-01-01 00:00:00';
    $event_time = strtotime($event_date);
    $diff = $event_time - time();
    echo floor($diff/(24*60*60)).' days to go for the great event';

?>

Note: I'm totally side stepping any timezone considerations, so, be sure you read up on timezone issues associated with using the PHP datetime functions.

Answer 2

jakemcgraw's answer would have my vote, had I 15 rep. :)

You might want to use mktime() instead of strtotime(), though.
