PHP time() Function – Returning the Current Unix Timestamp

The time() function in PHP returns the number of seconds that have elapsed since the Unix epoch (January 1, 1970 00:00:00 UTC).

Example usage shows how to compute the timestamp for one week from now by adding the appropriate number of seconds (7 days × 24 hours × 60 minutes × 60 seconds) to the current timestamp, and then format both the current date and the future date with date() :

<?php
$nextWeek = time() + (7 * 24 * 60 * 60);

echo 'Now: ' . date('Y-m-d') . "\n";

echo 'Next Week: ' . date('Y-m-d', $nextWeek) . "\n";
// or using strtotime():

echo 'Next Week: ' . date('Y-m-d', strtotime('+1 week')) . "\n";
?>

The script first prints the current date, then prints the date exactly one week later using the calculated timestamp, and finally shows an alternative approach using strtotime('+1 week') to achieve the same result.
