How to enable Mbstring?

It is required to have PHP mbstring enabled which supports for storing and displaying multi-byte characters in PHPKB software. The PHPKB knowledge base software will automatically detect that PHP extensions is enabled or not.

Why mbstring is required?

When we manipulate string encoded with the mbstring we need to use some special characters which have one or more consecutive bytes represent a single character in an encoding scheme. If we use non-multi byte aware string to the string function it fails to detect the beginning and end of the multibyte character and we probably miss some original data. Mbstring provided with the multi-byte string that helps to deal with the multiple byte encoding in PHP. It also helps to handle the character encoding conversions between the possible encoding pairs. Mbstring are also helps to handle the Unicode based encodings such as UTF-8 and UCS-2 and many single-byte encodings for convenience.
