From manual page: de paramètres

returns false when it should probably return the date of the first week of the year.

'W' is a date() compatible format

Test script:
$date = DateTime::createFromFormat('W','1');

Expected result:
it should return something like this:

public 'date' => string '2011-01-03 10:17:40' (length=19)
  public 'timezone_type' => int 3
  public 'timezone' => string 'UTC' (length=3)

Actual result:

"W" is not part of that list at all—it is not supported. The documentation also states

The format that the passed in string should be in. See the formatting options below. In *most cases*, the same letters as for the date() can be used.

Perhaps you're looking at an outdated translation of the manual? It looks that the French version of the manual is indeed outdated.

This is probably more of a feature request than a bug as 'W' isn't listed in the 
documentation for DateTime::createFromFormat neither are a few other characters 
that are supported by date.

You may as well just use the date() function if you wish to use 'W'

Marking as a datetime feature request.

To create a DateTime from a week you can use:

Thank you for your suggestion. As the previous comment suggests there is a way to solve this issue, so I'm closing this.
