Description:
------------
---
From manual page: https://php.net/dateinterval.construct
---
The "Example #1 DateInterval example" code now produces different output to that shown, since new properties have been added to the class. It doesn't state how to set any of these new properties with the constructor, in particular the microseconds property.

Test script:
---------------
<?php

$interval = new DateInterval('P2Y4DT6H8M');
var_dump($interval);

?>

Actual result:
--------------
class DateInterval#1 (16) {
  public $y =>
  int(2)
  public $m =>
  int(0)
  public $d =>
  int(4)
  public $h =>
  int(6)
  public $i =>
  int(8)
  public $s =>
  int(0)
  public $f =>
  double(0)
  public $weekday =>
  int(0)
  public $weekday_behavior =>
  int(0)
  public $first_last_day_of =>
  int(0)
  public $invert =>
  int(0)
  public $days =>
  bool(false)
  public $special_type =>
  int(0)
  public $special_amount =>
  int(0)
  public $have_weekday_relative =>
  int(0)
  public $have_special_relative =>
  int(0)
}
