fwiw, python parses this properly. I'm just seeing an empty array!
<form enctype="multipart/form-data" action='/fileupload.php' method=post>
<input multiple=true type=file name='file["my{}stuff"].data'><input type=submit
value='submit'></form>
var_dump($_FILES) yields:
array(0) {}
If I change the 'action' to a python script, I see this:
[ { 'file["my{}stuff"].dataâ, âtestfile2.txtâ, âthis is another test
file (2)\nâ }, { âfile["my{}stuff"].dataâ, âtestfile1.txtâ, âthis
is test file 1\nâ } ] ]
POST source:
Content-Type: multipart/form-data;

I indicated this as an mbstring related problem because the similar bugs I
found used this as the category.
See bugs 20114 19507 19347 20024 20133.

How come this could be a mbstring related problem..?

with the version of the form I posted, the expected and actual result sample
data should obviously reflect the strings "John" and "Doe" instead of "billy"
and "joel", respectfully.

Description:
------------
If key contains more than one set of square brackets, the key value pair is not
decoded properly. For example, a form with a series of input elements named
such as "formname[0].fieldname[0]" will cause incorrect and missing key/value
pairs to be stored into the $_POST array.
In researching the existing bug list, I noticed that there have been numerous
variations of bugs reported when form data contains url encoded data, such as
occurs when the brackets are encoded as %5b and %5d. However these bugs have
apparently been closed without actually fixing this problem. Perhaps a more
thorough analysis of this problem is warranted to keep it from lingering on for
a few more years before this report is closed. The Adobe acrobat
products/reader have just started to encode form names in this format, so it
could become a very serious issue if PHP cannot correctly process this form
data.
Reproduce code:
---------------
<html>
<head><title>Form Submit Test Script</title></head>
<body>
<form name='fm1' action="<? echo ($_SERVER["HTTP_REFERER"])?>" method='post'>
<input type='text' name='form1[0].firstname[0]' value='John' />
<input type='text' name='form1[0].lastname[0]' value='Doe' />
<input type='submit' />
</form>
<?
var_dump($_POST);
?>
</body>
</html>
Expected result:
----------------
array(2) { ["form1[0].firstname[0]"]=> string(5) "billy"
["form1[0].lastname[0]"]=> string(4) "joel" }
Actual result:
--------------
array(1) { ["form1"]=> array(1) { [0]=> string(4) "joel" } }
