mb_encode_mimeheader — Encode string for MIME header
Description
string mb_encode_mimeheader ( string $str [, string $charset = determined by mb_language() [, string $transfer_encoding = "B" [, string $linefeed = "\r\n" [, int $indent = 0 ]]]] )
Encodes a given string str
by the MIME header encoding scheme.
Parameters
-
str
-
The string being encoded. Its encoding should be same as mb_internal_encoding().
-
charset
-
charset
specifies the name of the character set in whichstr
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
).
Return Values
A converted version of the string represented in ASCII.
Examples
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; ?>
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.
