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 );
<?php
$dt = new DateTime;
if(isset($_GET['year']) && isset($_GET['week'])) {
$dt->setISODate($_GET['year'], $_GET['week']);
} else {
$dt->setISODate($dt->format('o'), $dt->format('W'));
}
$year = $dt->format('o');
$week = $dt->format('W');
?>
<a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week-1).'&year='.$year; ?>">Pre Week</a>
<a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week+1).'&year='.$year; ?>">Next Week</a>

With php 5.3

$NewTime = mktime(date('G'), date('i'), date('s'), date('n'), date('j') + $DaysToAdd, date('Y'));
From mktime documentation:
mktime() is useful for doing date arithmetic and validation, as it will automatically calculate the correct value for out-of-range input.
The advantage of this method is that you can add or subtract any time interval (hours, minutes, seconds, days, months, or years) in an easy to read line of code.
Beware there is a tradeoff in performance, as this code is about 2.5x slower than strtotime("+1 day") due to all the calls to the date() function. Consider re-using those values if you are in a loop.
The date_add() function should do what you want. In addition, check out the docs (unofficial, but the official ones are a bit sparse) for the DateTime object, it's much nicer to work with than the procedural functions in PHP.
You can also use Object Oriented Programming (OOP) instead of procedural programming:
$fiveDays = new DateInterval('P5D');
$today = new DateTime();
$fiveDaysAgo = $today->sub(fiveDays); // or ->add(fiveDays); to add 5 days
Or with just one line of code:
$fiveDaysAgo = (new DateTime())->sub(new DateInterval('P5D'));

while ($countDates < $max_dates) {
$NewDate=Date('F d, Y', strtotime("+".$countDates." days"));
