Description:
------------
Although the documentation claims every "Format accepted by date()" is accepted by DateTime::createFromFormat() (http://www.php.net/manual/en/datetime.createfromformat.php), the specifiers 'W' and 'w' are actually not.
So this is either a bug or a documentation-error.

Test script:
---------------
$mydate = DateTime::createFromFormat('W', '1');
print_r(DateTime::getLastErrors());

This missing feature (of w at least) requires parsing the english textual representation of days for localizing it. Obtaining an index would be much more efficient !

I am marking this as "Won't Fix". If this is still an issue, please open a new ticket at https://github.com/php/php-src/issues/

The documentation has been updated (a long time ago) to say:
In most cases, the same letters as for the date() can be used.
