Hier eine kurze Erklärung der Konfigurationsoptionen:

mbstring.language string

The default national language setting (NLS) used in mbstring. Note that this option automagically defines mbstring.internal_encoding and mbstring.internal_encoding should be placed after mbstring.language in php.ini

mbstring.encoding_translation boolean

Enables the transparent character encoding filter for the incoming HTTP queries, which performs detection and conversion of the input encoding to the internal character encoding.

mbstring.internal_encoding string
Warnung

This feature has been DEPRECATED as of PHP 5.6.0. Relying on this feature is highly discouraged.

Defines the default internal character encoding.

PHP 5.6 and later users should leave this empty and set default_charset instead.

mbstring.http_input string
Warnung

This feature has been DEPRECATED as of PHP 5.6.0. Relying on this feature is highly discouraged.

Defines the default HTTP input character encoding.

PHP 5.6 and later users should leave this empty and set default_charset instead.

mbstring.http_output string
Warnung

This feature has been DEPRECATED as of PHP 5.6.0. Relying on this feature is highly discouraged.

Defines the default HTTP output character encoding (output will be converted from the internal encoding to the HTTP output encoding upon output).

PHP 5.6 and later users should leave this empty and set default_charset instead.

mbstring.detect_order string

Defines default character code detection order. See also mb_detect_order().

mbstring.substitute_character string

Defines character to substitute for invalid character encoding.

mbstring.func_overload string

Overloads a set of single byte functions by the mbstring counterparts. See Function overloading for more information.

This setting can only be changed from the php.ini file.

mbstring.strict_detection boolean

Enables the strict encoding detection.

According to the » HTML 4.01 specification, Web browsers are allowed to encode a form being submitted with a character encoding different from the one used for the page. See mb_http_input() to detect character encoding used by browsers.

Although popular browsers are capable of giving a reasonably accurate guess to the character encoding of a given HTML document, it would be better to set the charset parameter in the Content-Type HTTP header to the appropriate value by header() or default_charset ini setting.

Beispiel #1 php.ini setting examples

; Set default language
mbstring.language        = Neutral; Set default language to Neutral(UTF-8) (default)
mbstring.language        = English; Set default language to English 
mbstring.language        = Japanese; Set default language to Japanese

;; Set default internal encoding
;; Note: Make sure to use character encoding works with PHP
mbstring.internal_encoding    = UTF-8  ; Set internal encoding to UTF-8

;; HTTP input encoding translation is enabled.
mbstring.encoding_translation = On

;; Set default HTTP input character encoding
;; Note: Script cannot change http_input setting.
mbstring.http_input           = pass    ; No conversion. 
mbstring.http_input           = auto    ; Set HTTP input to auto
                                ; "auto" is expanded according to mbstring.language
mbstring.http_input           = SJIS    ; Set HTTP input to SJIS
mbstring.http_input           = UTF-8,SJIS,EUC-JP ; Specify order

;; Set default HTTP output character encoding 
mbstring.http_output          = pass    ; No conversion
mbstring.http_output          = UTF-8   ; Set HTTP output encoding to UTF-8

;; Set default character encoding detection order
mbstring.detect_order         = auto    ; Set detect order to auto
mbstring.detect_order         = ASCII,JIS,UTF-8,SJIS,EUC-JP ; Specify order

;; Set default substitute character
mbstring.substitute_character = 12307   ; Specify Unicode value
mbstring.substitute_character = none    ; Do not print character
mbstring.substitute_character = long    ; Long Example: U+3000,JIS+7E7E

Beispiel #2 php.ini setting for EUC-JP users

;; Disable Output Buffering
output_buffering      = Off

;; Set HTTP header charset
default_charset       = EUC-JP    

;; Set default language to Japanese
mbstring.language = Japanese

;; HTTP input encoding translation is enabled.
mbstring.encoding_translation = On

;; Set HTTP input encoding conversion to auto
mbstring.http_input   = auto 

;; Convert HTTP output to EUC-JP
mbstring.http_output  = EUC-JP    

;; Set internal encoding to EUC-JP
mbstring.internal_encoding = EUC-JP    

;; Do not print invalid characters
mbstring.substitute_character = none   

Beispiel #3 php.ini setting for SJIS users

;; Enable Output Buffering
output_buffering     = On

;; Set mb_output_handler to enable output conversion
output_handler       = mb_output_handler

;; Set HTTP header charset
default_charset      = Shift_JIS

;; Set default language to Japanese
mbstring.language = Japanese

;; Set http input encoding conversion to auto
mbstring.http_input  = auto 

;; Convert to SJIS
mbstring.http_output = SJIS    

;; Set internal encoding to EUC-JP
mbstring.internal_encoding = EUC-JP    

;; Do not print invalid characters
mbstring.substitute_character = none

Note that you should better at least set "mbstring.internal_encoding".

Just check as below:

<?php

echo mb_internal_encoding() . '<br />';
echo
mb_regex_encoding();

?>

You might be surprised at unexpected values.

eg.

mbstring.language Japanese
;mbstring.internal_encoding (commented out showing "no value" in phpinfo() )

These two lines in "php.ini" are the same values as

mb_internal_encoding("EUC-JP");
mb_regex_encoding("EUC-JP");

in Win / Linux servers.

"mbstring.internal_encoding" defines the default encoding for "mb_" Functions such as "mb_strlen()".

It also defines the same for "mb_ereg_" Functions such as "mb_ereg()" when you don't set "mb_regex_encoding".
