mb_encode_mimeheader — Encode string for MIME header
$str
[, string $charset = mb_language()
[, string $transfer_encoding = "B"
[, string $linefeed = "\r\n"
[, int $indent = 0
]]]] ) : string
Encodes a given string
str by the MIME header encoding scheme.
strThe string being encoded. Its encoding should be same as mb_internal_encoding().
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).
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).
A converted version of the string represented in ASCII.
Beispiel #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;
?>
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.
