mb_encode_mimeheader — Encode string for MIME header

Beschreibung

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.

Parameter-Liste

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 ).

Rückgabewerte

A converted version of the string represented in ASCII.

ChangeLog

Version Beschreibung 5.0.0 The indent parameter was added.

Beispiele

Beispiel #1 mb_encode_mimeheader() example

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

Anmerkungen

Hinweis: 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.
