mb_encode_mimeheader()

mb_encode_mimeheader() — Encode string for MIME header.

mb_encode_mimeheader() — Encodes a given string string by the MIME header encoding scheme.

Inputs: 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 “rn” (CRLF) if not given.

Returns: A converted version of the string represented in ASCII.
