bool 
mb_ereg_search ( [string pattern [, string option]] )
     mb_ereg_search() returns TRUE if the
     multibyte string matches with the regular expression, FALSE for
     otherwise. The string for matching is set by

     pattern is not specified, the previous one
     is used.
    
     The internal encoding or the character encoding specified in

     encoding.
