mb_strtoupper
MB_STRTOUPPER(3) 1 MB_STRTOUPPER(3)
mb_strtoupper - Make a string uppercase
SYNOPSIS
string mb_strtoupper (string $str, [string $encoding = mb_internal_encoding()])
DESCRIPTION
Returns $str with all alphabetic characters converted to uppercase.
PARAMETERS
o $str
- The string being uppercased.
o $encoding
-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
RETURN VALUES

UNICODE
For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/.
By contrast to strtoupper(3), '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 (a).
EXAMPLES
Example #1
mb_strtoupper(3) 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
?>
Example #2
mb_strtoupper(3) example with non-Latin UTF-8 text
<?php
$str = "Txiotn a
nE Baos unuvn yn, dpaokeCei unp vw0po kuvs";
$str = mb_strtoupper($st_, 'UTF-8'); _ _ _ _
echo $str; // Prints TXI>TH A/TTHH BAO> YHMNH | H, /PA>KE/EI YTTP NOOPO KYN>
