                                 mb_strtoupper

   (PHP 4 >= 4.3.0)
   mb_strtoupper -- Make a string uppercase

Description

   string mb_strtoupper ( string str [, string encoding])

   mb_strtoupper() returns str with all alphabetic characters converted
   to uppercase.

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

   By contrast to strtoupper(), 'alphabetic' is determined by 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_strtoupper() example
   <?php
   $str = "Mary Had A Little Lamb and She LOVED It So";
   $str = mb_strtoupper($str);
   echo $str; // Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
   ?>
