mode
mode 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. |
encoding
The optional encoding parameter specifies the character set to represent the result by. If omitted or null, iconv.internal_encoding will be used.
Returns a decoded MIME field on success, or false if an error occurs during the decoding.
| Version | Description |
|---|---|
| 8.0.0 | encoding is nullable now. |
