# mb_encode_mimeheader

(PHP 4 >= 4.0.6, PHP 5)

mb_encode_mimeheader — Encode string for MIME header

### 설명

string mb_encode_mimeheader ( string `$str` [, string `$charset` [, string `$transfer_encoding` [, string `$linefeed` [, int `$indent` ]]]] )

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

### 인수

`str`

  The string being encoded.

`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() should be set to same encoding.

`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.

`linefeed`

  `linefeed` specifies the EOL (end-of-line) marker with which mb_encode_mimeheader() 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 "\r\n" (CRLF) if not given.

`indent`

  Indentation of the first line (number of characters in the header before `str` ).

### 반환값

A converted version of the string represented in ASCII.

### 변경점

버전 | 설명
--- | ---
5.0.0 | The `indent` parameter was added.

### 예제

Example #1 mb_encode_mimeheader() example

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

### 주의

> 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.
