I have reported this problem in http://bugs.php.net/bug.php?id=49238. It
would appear that this option, which was first made available in PHP 4.2.0,
has been silently dropped. Apparently the decision was made in order to fix
http://bugs.php.net/bug.php?id=43227, but nothing was explicitly stated in
the bug report, nor in any release notes, and the documentation still has
not been updated to reflect this change even after 6 months.
This causes a problem if your site is on a shared server and you don't have
access to either php.ini or httpd.conf. If this option is turned off by
default, then how do you turn it on? If it is on by default then how do you
turn it off? It needs to be turned off for phpMyAdmin otherwise it will
issue a message warning about possible data corruption.
Should this option be reinstated?

I think you can turn off mbstring overloading by setting internal mbstring
encoding to 'pass'. Instead of turning mbstring overloading on you should
use mbstring functions.

You THINK it can be turned off this way? That's not good enough. Does it
actually work? Where is it documented?

Works for me. See SquirrelMail functions/i18n.php set_up_language() function.

There is no set_up_language() function, and what has SquirrelMail got to do
with PHP?
Unless you can point to some official documentation on the PHP web site your
"advice" is totally unsubstantiated and virtually worthless.

He was referring to set_up_language() defined within SquirrelMail's
functions/i18n.php which contains:
// mbstring.func_overload<>0 fix. See cvs HEAD comments.
if ($squirrelmail_language != 'ja_JP' &&
function_exists('mb_internal_encoding') &&
check_php_version(4,2,0) &&
(int)ini_get('mbstring.func_overload')!=0) {
mb_internal_encoding('pass');
}
among other things. This appears to be what he was referring to,
particularly the "mb_internal_encoding('pass');" call.

As for hints in the documentation, see mb_internal_encoding() and the
comments for mb_http_output(), which mentions the 'pass' encoding type.

You are missing the point. I'm not trying to set the encoding for any HTML
output as that is handled differently. What I am concerned about is the
func_overload option which, ever since PHP 4.2.0, we have been able to turn
on or off using an htaccess directive on a PERDIR basis. Although neither
the documentation nor the release notes have been changed the PERDIR option
has disappeared and it is now set either on or off for the entire system and
cannot be modified with any htaccess or ini_set directive.
So if func_overload is turned on, how do I turn it off? If it is turned off
how do I turn it on?
Considering that phpMyAdmin does not like it to be turned on, this is not a
trivial point.

Simply doing a search in the bug system would have revealed the current

The documentation team just hasn't got around changing the docs yet and
adding a note about it there. Feel free to provide a patch or forever be
silent.

No need, fixed in the doc svn.

This "advice" is the only advice that you got. :) It might be worthless,
but it comes from PHP script developer who specializes in
internationalization stuff and who had to make sure that his stuff works
without any .htaccess modifications in environment thrashed by
mbstring.func_overload.
Setting mbstring internal encoding to 'pass' fixed string length
evaluation issues in code which worked with random 8bit strings. Those
random strings store encoded passwords and any data corruption would
result authentication error. ereg and mail overrides were not tested,
because code rarely uses ereg functions and does not use PHP mail().
Thanks to Dave for looking up the code I was referring too.
