The question is what should be supported. mbstring is not a default
extension and function overloading is not the default setting in this
extension. If we follow a 80:20 or even a 90:10 rule this is not a ZF
bug, just a not supported extension/setting.
But as soon as we raise the required PHP version to 5.2 we should use
the binary-cast, so we would be compatible with PHP6.
In the meanwhile there is a workaround. mstring.func_overloaded can
be set per directory, but it's not recommended. Maybe it'd be better
to use runkit if overloading is really needed, because it can be
controlled per request.

Hi all,
I am working on one of the Http_Client bugs, ZF-2098, which
describes a
problem the Http_Client has when sending multi-byte encoded (eg. UTF8
Chinese) text in the request body when mbstring is loaded and
overloads
the strlen() function. This happens because I've been using strlen
() to
calculate the body size (in bytes - not in characters).
This works in most cases, but when mbstring overloads strlen with
mb_strlen - what you get is the string length in characters and not in
bytes.
Brian DeShong already proposed a patch fixing the problem, but I've
found that there are several Zend_Http classes that suffer from the
same
problem. I'm sure that other ZF classes, as well as users, who need a
transparent way to calculate string length in bytes, irregardless of
loaded extensions or PHP version (no idea what PHP 6 / 5.3 would cause
in this case).
So, is there any component of the framework where you would see a
static ::strByteLength($string) method? I was going to implement
one in
Zend_Http_Client - but it's not really Zend_Http_Client specific.
Suggestions welcome ;)
Shahar.
