Description:
------------
I don't know if this is expected behaviour or not, but parsing a date without a day, will produce a result where 'day' will be set to 1. If this is expected, there really should be a parameter that disables this. I'm using this for user provided data, and it's not really valid.

Test script:
---------------
var_dump(date_parse("May 2013"));

Expected result:
----------------
  ["day"]=>
  bool(false)


Actual result:
--------------
  ["day"]=>
  int(1)

This is expected behaviour, see "Textual month and four digit year (Day reset to 1)" on http://php.net/manual/de/datetime.formats.date.php

Indeed, this is documented behavior!

Documented behaviour does not make it correct behaviour.

Currently I have no way of testing if the day field is default or was actually parsed from the input.

If you want more control over parsing dates, where the behaviour of strtotime/ the DateTime constructor does not apply, you can use the date_parse_from_format function, like:

php -r 'var_dump(date_parse_from_format("M Y", "May 2013"));'

This will then show you the right information:

array(12) {
  'year' =>
  int(2013)
  'month' =>
  int(5)
  'day' =>
  bool(false)
