Returns an associative array that holds a whole set of MIME header fields specified by encoded_headers on success, or FALSE if an error occurs during the decoding.
Each key of the return value represents an individual field name and the corresponding element represents a field value. If more than one field of the same name are present, iconv_mime_decode_headers() automatically incorporates them into a numerically indexed array in the order of occurrence.
mode determines the behaviour in the event iconv_mime_decode_headers() encounters a malformed MIME header field. You can specify any combination of the following bitmasks.
Table 1. Bitmasks acceptable to iconv_mime_decode_headers()
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. |
The optional charset parameter specifies the character set to represent the result by. If omitted, iconv.internal_charset will be used.
