Hi Simon,
starting with Moodle 1.5 and widely used in next Moodle 1.6 a lot of strings functions are being processed by a new text library in order to be able to handle different charsets properly, specially the UTF-8 one.
This library tries to do its work by using the mbstring or iconv libraries and, if they aren't present, a fallback mechanism to use internal functions is used instead. As these internal functions are written in PHP code, they will be slower that their mbstring/iconv counterparts.
And this is the primary reason to recommend mbstring/iconv. They are solid libraries and pretty faster than the alternative internal (PHP) functions.
Ciao

Uncomment this line in your php.ini:
extension=php_mbstring.dll
Hope this helps!
Ken
extension=php_mbstring.dll
Hope this helps!

By uncomment do you mean remove the ';' at the start of the line? If so it didn't work.

Are you using Linux or Windows and do you have a hosted moodle or direct access? Also it would be helpful if you could attach your php.ini and your the output from phpinfo (in moodle 1.6 this is in Administration, Miscellaneous, Environment - there is a button at the bottom of the page).

Hi Ken
I am using Windows and it is direct access. Attached is the php.ini file. How would you like me to display the phpinfo file?

Can you double check that you have the file php_mbstring.dll in the directory c:\php\ext and that it is the correct version (right click, properties, version, file version should be 5.1.4.x - if you're running php 5.1.4).
For the phpinfo, there is a more efficient method: at the command prompt, type php -i > phpinfo.txt. Attach the phpinfo.txt to your post.

php ver 5.1.2
php_mbstring.dll does exist and is version 5.1.2.2
phpinfo.txt attached.

Looking at the phpinfo I can see mbstring has loaded:
mbstring
Multibyte Support => enabled
Multibyte string engine => libmbfl
Multibyte (japanese) regex support => enabled
Multibyte regex (oniguruma) version => 3.7.1
So all's well and your php is using the library in the background.

Red Has has mbstring extension packaged as a standard RPM as part of the system. Have a look in your installation CDs.

Please guys i have same question of Jose. I really need answer. I'd like to enable the mbstring under Linux. The following is the mbstring section in my php.ini. Should i change or uncomment anything to enable it.
[mbstring]
; language for internal character representation.
;mbstring.Xlanguage= Japanese
; internal/script encoding.
; Some encoding cannot work as internal encoding.
; (e.g. SJIS, BIG5, ISO-2022-*)
;mbstring.internal_encoding = EUC-JP
; http input encoding.
;mbstring.http_input = auto
; http output encoding. mb_output_handler must be
; registered as output buffer to function
;mbstring.http_output = SJIS
; enable automatic encoding translation accoding to
; mbstring.internal_encoding setting. Input chars are
; converted to internal encoding by setting this to On.
; Note: Do _not_ use automatic encoding translation for
; portable libs/applications.
;mbstring.encoding_translation = Off
; automatic encoding detection order.
; auto means
;mbstring.detect_order = auto
; substitute_character used when character cannot be converted
; one from another
;mbstring.substitute_character = none;
; overload(replace) single byte functions by mbstring functions.
; mail(), ereg(), etc are overloaded by mb_send_mail(), mb_ereg(),
; etc. Possible values are 0,1,2,4 or combination of them.
; For example, 7 for overload everything.
; 0: No overload
; 1: Overload mail() function
; 2: Overload str*() functions
; 4: Overload ereg*() functions
;mbstring.func_overload = 0

As Iñaki points out, most linux distributions have mbstring available as a package which you can add manually. Search the rpmfind.net database, download using wget and then install using rpm -ivh. Alternatively, if you have yum, type "yum install php-mbstring".

Thank you so much for your reply. Unfortunately the yum did not work out. If I got and installed the rpm package, should I reconfigure the php?

Hi I am trying to install mbstring on the following system:
Windows 2003
Apache 2.2.6
PHP 5.2.5
moodle 1.8.3
It says that this is missing. When i try to install the extension from the msi installer i can not find the extension 'mbstring'
I go to the php.ini and there is details on mbstring as stated as the follows:
[mbstring]
; language for internal character representation.
;mbstring.Xlanguage= Japanese
; internal/script encoding.
; Some encoding cannot work as internal encoding.
; (e.g. SJIS, BIG5, ISO-2022-*)

; http input encoding.
;mbstring.http_input = auto
; http output encoding. mb_output_handler must be
; registered as output buffer to function
;mbstring.http_output = SJIS
; enable automatic encoding translation according to
; mbstring.internal_encoding setting. Input chars are
; converted to internal encoding by setting this to On.
; Note: Do _not_ use automatic encoding translation for
; portable libs/applications.
;mbstring.encoding_translation = Off
; automatic encoding detection order.
; auto means
;mbstring.detect_order = auto
; substitute_character used when character cannot be converted
; one from another
;mbstring.substitute_character = none;

; 0: No overload
; 1: Overload mail() function
; 2: Overload str*() functions
; 4: Overload ereg*() functions
;mbstring.func_overload = 0
; enable strict encoding detection.
;mbstring.strict_encoding = Off
There is no 'extension=php_mbstring'
Any ideas????
