                                mb_convert_case

   (PHP 4 >= 4.3.0)
   mb_convert_case -- Perform case folding on a string

Description

   string mb_convert_case ( string str, int mode [, string encoding])

   mb_convert_case() returns case folded version of string converted in
   the way specified by mode.

   mode can be one of MB_CASE_UPPER, MB_CASE_LOWER or MB_CASE_TITLE.

   encoding specifies the encoding of str; if omitted, the internal
   character encoding value will be used.

   The return value is str with the appropriate case folding applied.

   By contrast to the standard case folding functions such as
   strtolower() and strtoupper(), case folding is performed on the basis
   of the Unicode character properties. Thus the behaviour of this
   function is not affected by locale settings and it can convert any
   characters that have 'alphabetic' property, such as A-umlaut ().

   For more information about the Unicode properties, please see
   http://www.unicode.org/unicode/reports/tr21/.

   Example 1. mb_convert_case() example
   <?php
   $str = "mary had a Little lamb and she loved it so";
   $str = mb_convert_case($str, MB_CASE_UPPER, "UTF-8");
   echo $str; // Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
   $str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
   echo $str; // Prints Mary Had A Little Lamb And She Loved It So
   ?>

   See also mb_strtolower(), mb_strtoupper(), strtolower() and
   strtoupper().
