Increase days to php current Date()

Question

How do I add a certain number of days to the current date in PHP?

I already got the current date with:

$today = date(\'y:m:d\');

If you need this code in several places then I'd suggest that you add a short function to keep your code simpler and easier to test.

function add_days( $days, $from_date = null ) {
    if ( is_numeric( $from_date ) ) { 
        $new_date = $from_date; 
    } else { 
        $new_date = time();
    }

    // Timestamp is the number of seconds since an event in the past
    // To increate the value by one day we have to add 86400 seconds to the value
    // 86400 = 24h * 60m * 60s
    $new_date += $days * 86400;

    return $new_date;
}

Then you can use it anywhere like this:

$today       = add_days( 0 );
$tomorrow    = add_days( 1 );
$yesterday   = add_days( -1 );
$in_36_hours = add_days( 1.5 );

$first_reminder  = add_days( 10 );
$second_reminder = add_days( 5, $first_reminder );
$last_reminder   = add_days( 3, $second_reminder );
