provide access to the PCRE (perl compatible-regular-expressions) library for pattern matching. The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. This syntax can often handle more complex expressions and capturing than standard regular expression implementations. For more information about PCRE, please see: http://www.pcre.org/ lib_mysqludf_preg is a useful performance optimization for those applications that are already performing these regular expression matches in a high level language (ie. PHP) on the client side. It is also helpful when there is a need to capture a parenthesized subexpression from a regular expression, or simply as a slight performance boost over the builtin RLIKE/REGEXP functions.
