Adding or Subtracting Dates in PHP

Working with dates within PHP sometimes come in handy, yet the syntax is not quite something that is easy to remember. You can add or subtract; days, months and years to the current date by using the mktime() function.


Here is some quick PHP code to add a month to the current date:

$next_month = mktime(0, 0, 0, date("m")+1, date("d"), date("y"));
$outDate = date("Y-m-d", $next_month);
