MB_CONVERT_CASE(3)							 1							MB_CONVERT_CASE(3)

mb_convert_case - Perform case folding on a string

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).

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

EXAMPLES

       Example #1

	      mb_convert_case(3) 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
	      ?>

       Example #2

	      mb_convert_case(3) example with non-Latin UTF-8 text

	      <?php
	      $str = "Txiotn a
nE Baos unuvn yn, dpaokeCei unp vw0po kuvs";
	      $str = mb_convert_case($_tr, MB_CASE_UP_ER, "UTF_8");   _ 		     _
	      echo $str; // Prints TXI>TH A/TTHH BAO> YHMNH | H, /PA>KE/EI YTTP NOOPO KYN>
	      $str = mb_convert_case($str, MB_CASE_TITLE, "U_F-8");
	      echo $str; // Prints Txiotn A
nE Baoo Ynuvn | n, /paokeCei Ynp Nw0po Kuvo
	      ?>

MB_ENCODE_MIMEHEADER(3) 						 1						   MB_ENCODE_MIMEHEADER(3)

mb_encode_mimeheader - Encode string for MIME header

SYNOPSIS

       string m0],n[int_m$indent]) (string  $str, [string  $charset = mb_internal_encoding()], [string	$transfer_encoding = "B"], [string  $line-
       feed = "

DESCRIPTION

	Encodes a given string$str by the MIME header encoding scheme.

PARAMETERS

	      o $str
		- The string being encoded.

	      o $charset
		-$charset specifies the name of the character set in which $str is represented in. The default value is determined by the  current
		NLS setting ( mbstring.language). mb_internal_encoding(3) should be set to same encoding.

	      o $transfer_encoding
		-$transfer_encoding  specifies the scheme of MIME encoding. It should be either "B" (Base64) or "Q" (Quoted-Printable). Falls back
		to "B" if not given.

	      o $linefeed
		-$linefeed specifies the EOL (end-of-line) marker with which mb_encode_mimeheader(3) performs line-folding (a RFC term, the act of
		breaking a line longer than a certain length into multiple lines. The length is currently hard-coded to 74 characters). Falls back
		to "
" (CRLF) if not given.

	      o $indent
		- Indentation of the first line (number of characters in the header before $str).

RETURN VALUES

	A converted version of the string represented in ASCII.

EXAMPLES

       Example #1

	      mb_encode_mimeheader(3) example

	      <?php
	      $name = ""; // kanji
	      $mbox = "kru";
	      $doma = "gtinn.mon";
	      $addr = mb_encode_mimeheader($name, "UTF-7", "Q") . " <" . $mbox . "@" . $doma . ">";
	      echo $addr;
	      ?>

NOTES

       Note

	       This function isn't designed to break lines at higher-level contextual break points (word boundaries,  etc.).  This  behaviour  may
	      clutter up the original string with unexpected spaces.
