What is the alternative method to add 1 hour to the server time in PHP?

When adding 1 hour to the server time in PHP, an alternative method is to use the `date()` function in combination with `strtotime()` to add the desired time interval. This method allows for easy manipulation of time values without the need for complex calculations.

// Get the current server time
$server_time = date('Y-m-d H:i:s');

// Add 1 hour to the server time
$updated_time = date('Y-m-d H:i:s', strtotime($server_time . ' +1 hour'));

// Output the updated time
echo $updated_time;
