I am developing a web-based system for university
students to submit assignments over the web. This
involves uploading files via HTTP POST method,
with a PHP script on the receiving end. The page
I designed works with Netscape Navigator, Mozilla,
and Internet Explorer, but not with Opera 5 for
Linux or Windows: PHP obviously gets confused by
the data that Opera sends.

I've set up a test page to demonstrate the
behaviour at
with the source code at

After I tested this also with non-php CGI script, I'm
totally sure that this is NOT php bug but a bad bug 
in Opera for Linux. I tried also with the Opera/Win32 5.11
and it works just fine.

I submitted a bug report to Opera but feel free to do 
so too.

Here's what I received from the Opera folks.  They admit the
bug, but claim that PHP also doesn't implement the RFC 100%.


Subject: Your Opera Bug report

Thank you for reporting this bug, and for taking the 
trouble to develop a test page.
The bug was known and is fixed in the next release of Opera
Versions 5.02 and earlier of Opera also function correctly.

What happened was that it was noticed that Opera did not
comply with the RFC
governing multipart mime attachments for forms (where
headers should be able to
be split across lines). Opera was brought into compliance
for version 5.1, but it
was then discovered that several major procesing languages
(php, coldfusion and miva)
do not comply with the RFC either.
