The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.

我发现 上有介绍说:

mbstring provides multibyte specific string functions that help you deal with multibyte encodings in PHP.

Note: If you are connecting to a database with PHP, it is recommended that you use the same character encoding for both the database and the internal encoding for ease of use and better performance.
If you are using PostgreSQL, the character encoding used in the database and the one used in PHP may differ as it supports automatic character set conversion between the backend and the frontend.


“JIS, SJIS, ISO-2022-JP, BIG-5”

Example#1 php.ini 设置的例子

; 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 to “ASCII,JIS,UTF-8,EUC-JP,SJIS”

mbstring.http_input = SJIS ;Set HTTP2 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
