# mb_convert_case

(PHP 4 >= 4.3.0, PHP 5)

mb_convert_case — Perform case folding on a string

### 설명

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

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

### 인수

`str`

  The string being converted.

`mode`

  The mode of the conversion. It can be one of `MB_CASE_UPPER`, `MB_CASE_LOWER`, or `MB_CASE_TITLE`.

`encoding`

  `encoding` 인수는 문자 인코딩입니다. 생략하면, 내부 문자 인코딩값을 사용합니다.

### 반환값

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

### 유니코드

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 (Ä).

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

### 예제

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
?>`

### 참고

- mb_strtolower() - Make a string lowercase
- mb_strtoupper() - Make a string uppercase
- strtolower() - 문자열을 소문자로 만듭니다
- strtoupper() - 문자열을 대문자로 만듭니다
- ucfirst() - Make a string's first character uppercase
- ucwords() - Uppercase the first character of each word in a string
