The PHP mbstring functions provide support for languages represented by multi-byte character sets, e.g., Chinese, Japanese, Korean, Russian and more. See the PHP manual section on mbstring for more information on how this might affect you.
phpMyAdmin sometimes requires these functions to properly display database information, though no database corruption should result if it is not installed .
For Windows users having particular difficulty installing the extension, this forum link suggests the following:
php_mbstring.dll(included only in the .zip distribution of php) in the
extsubdirectory of your PHP install (for example, in to
php.iniand verify or add the following:
- Correct extension_dir:
; Directory in which the loadable extensions (modules) reside. extension_dir = C:\PHP\ext
- Dynamic Extensions (near other lines of "extension=..."):
- In the Windows Extension section, un-comment (by removing the semi-colon):
- Now save php.ini; a web-server restart may be needed for the changes to take effect.
