[PSR-7] $_FILES behavior wrong description

[Benoît Burnichon]

Hello,

I have a legacy application where I included PSR-7 specification in the process of modernizing.

Looking at the PSR-7 section about UploadedFileInterface, I saw some false descriptions of how $_FILES works.

I uploaded a file in 'my-form[details][avatar]' field of form-data, I ended up with the following array in $_FILES:

Version of PHP used:

PHP 5.6.27-0+deb8u1 (cli) (built: Oct 15 2016 15:53:28)

array (
  'my-form' => array (
    'name' => array (
      'details' => array (
        'avatars' => 'learny-bn.jpg',
      ),
    ),
    'type' => array (
      'details' => array (
        'avatars' => 'image/jpeg',
      ),
    ),
    'tmp_name' => array (
      'details' => array (
        'avatars' => '/data/tmp/phpRq7Gzy',
      ),
    ),
    'error' => array (
      'details' => array (
        'avatars' => 0,
      ),
    ),
    'size' => array (
      'details' => array (
        'avatars' => 19600,
      ),
    ),
  ),
)

As you can see, it is different from what is indicated in behavior description where all 5 keys are in the same leaf array. Instead, I have keys of second level of $_FILES being 'tmp_name', 'name', 'size', 'type' & 'error'.

I think this description file should be changed as implementors could be misled by the wrong description. Or did I missed something in my config?

Cheers,

Benoît
