Bug description: _FILES unintuitive when arrays used.
PHP seems to mix up array-based file uploads. In the
simple example code I've attached, pick any two files,
and you'll get an array that looks like this:
$_FILES =
[thing]=> Array
(
[name][test] => ...
[type][test] => ...
[tmp_name][test] => ...
[error][test] => ...
[size][test] => ...
)
[other] => Array
(
[name] => ...
[type] => ...
[tmp_name] => ...
[error] => ...
[size] => ...
)
But you'd expect from how the last array works, that the
elements: name, type, tmp_name, error, size, are associated
with the actual uploaded file. In that case, you'd expect:
[thing]=> Array
(
[test] => Array
(
[name] => ...
[type] => ...
[tmp_name] => ...
[error] => ...
[size] => ...
)
)
[other] => Array
(
[name] => ...
[type] => ...
[tmp_name] => ...
[error] => ...
[size] => ...
)
This makes the $_FILES variable virtually impossible to
use in a foreach or while context, as all of the
associated elements are not associated with the array
elements, but vice versa.
This is also the crux of the problem that caused $_FILES
to be removed from $_REQUEST in CVS. Since, if I have an
element named stuff[name] in a form upload, and a file
called stuff[thing], then the $_REQUEST variable would
contain stuff[name][thing] when it should be
stuff[thing][name] and stuff[name] as separate elements.
