determines the behaviour in the event iconv_mime_decode() encounters a malformed MIME header field. You can specify any combination of the following bitmasks.
Value | Constant | Description |
---|---|---|
1 | ICONV_MIME_DECODE_STRICT | If set, the given header is decoded in full conformance with the standards defined in » RFC2047. This option is disabled by default because there are a lot of broken mail user agents that don't follow the specification and don't produce correct MIME headers. |
2 | ICONV_MIME_DECODE_CONTINUE_ON_ERROR | If set, iconv_mime_decode_headers() attempts to ignore any grammatical errors and continue to process a given header. |
charset
The optional charset
parameter specifies the character set to represent the result by. If omitted, iconv.internal_encoding will be used.
Returns:
Returns a decoded MIME field on success, or FALSE
if an error occurs during the decoding.
