mb_encode_mimeheader

(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

mb_encode_mimeheaderEncode string for MIME header

Description

mb_encode_mimeheader(
    string $string,
    ?string $charset = null,
    ?string $transfer_encoding = null,
    string $newline = "\r\n",
    int $indent = 0
): string

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

Parameters

string

The string being encoded. Its encoding should be same as mb_internal_encoding().

charset

charset specifies the name of the character set in which string is represented in. The default value is determined by the current NLS setting (mbstring.language).

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.

newline

newline 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 string).

Return Values

A converted version of the string represented in ASCII.

Changelog

Version Description
8.0.0 charset and transfer_encoding are nullable now.

Examples

Example #1 mb_encode_mimeheader() example

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

The above example will output:

"=?UTF-7?Q?+WSqQzg-?=" <kru@gtinn.mon>

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.
