Helper for parsing headers attributes
I'm missing a helper for parsing headers, i.e something that turns attachment; filename="example.php" into [filename => 'example.php']
@JanTvrdik Is there a standard for this? I haven't looked myself.
Shouldn't it be more something like [attachment => NULL, filename => 'example.php'] ?
Is there a standard for this?
It depends afaik. There is standard for Accept headers as well as Content-Type header (RFC 7231) at least.
It's not in one place, but if summarized, it leads to http://search.cpan.org/~ether/HTTP-Message-6.11/lib/HTTP/Headers/Util.pm
Uf, as it turned out there is no unified standard (as pointed out for example here). So I guess we need to pick a list of headers which we actually want to be able to parse decide based on that.
The stuff is so fucked up that even browsers don't implement it correctly http://greenbytes.de/tech/tc/httpcontenttype/
