--------------------------+-----------------------------
 When you have form code that references [several file
 uploads](http://php.net/manual/en/features.file-upload.multiple.php) as
 array, the media_handle_upload() function fails to handle this.
 For example this:

 {{{
 <input type="file" name="documents[]">
 <input type="file" name="documents[]">
 }}}

 Will result in a $_FILES array that's creates subarrays shaped like so:

 {{{
 $_FILES['userfile']['name'][0]
 $_FILES['userfile']['name'][1]
 $_FILES['userfile']['tmp_name'][0]
 $_FILES['userfile']['tmp_name'][1]
 $_FILES['userfile']['size'][0]
 $_FILES['userfile']['size'][1]
 $_FILES['userfile']['type'][0]
 $_FILES['userfile']['type'][1]
 }}}


 This will fail when passed to media_handle_upload, since [the
 implementation does not handle this array
 structure](https://core.trac.wordpress.org/browser/tags/4.5.3/src/wp-
 admin/includes/media.php#L281) nor is this documented.
