properties - Undocumented Properties for DateInterval Class

问题描述

When I vardump a DateInterval object, in PHP 7.2.1, I get the following output:

object(DateInterval)#4 (16) {
  ["y"]=>
  int(0)
  ["m"]=>
  int(0)
  ["d"]=>
  int(14)
  ["h"]=>
  int(0)
  ["i"]=>
  int(0)
  ["s"]=>
  int(0)
  ["f"]=>
  float(0)
  ["weekday"]=>
  int(0)
  ["weekday_behavior"]=>
  int(0)
  ["first_last_day_of"]=>
  int(0)
  ["invert"]=>
  int(0)
  ["days"]=>
  int(14)
  ["special_type"]=>
  int(0)
  ["special_amount"]=>
  int(0)
  ["have_weekday_relative"]=>
  int(0)
  ["have_special_relative"]=>
  int(0)
}

There is another thread with the same question but is marked as duplicate. The link given here doesn't describe what I want to know.

NOTE: I am able to access all the properties for these DateInterval Object. I need a little knowledge about the properties not mentioned in the documentation.

Please tell me what are these properties?
