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).

SYNOPSIS

       string mb_convert_case (string  $str, int  $mode, [string  $encoding = mb_internal_encoding()])

DESCRIPTION

	Performs case folding on a string, converted in the way specified by $mode.

PARAMETERS

	      o $str
		- The string being converted.

	      o $mode
		- The mode of the conversion. It can be one of MB_CASE_UPPER, MB_CASE_LOWER, or MB_CASE_TITLE.

	      o $encoding
		-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.

RETURN VALUES

	A case folded version of $string converted in the way specified by $mode.

UNICODE

	By  contrast to the standard case folding functions such as strtolower(3) and strtoupper(3), 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 (A).
