Description

string iconv_mime_decode ( string encoded_header [, int mode [, string charset]] )

Table 1. Bitmasks acceptable to iconv_mime_decode()

ValueConstantDescription
1ICONV_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.
2ICONV_MIME_DECODE_CONTINUE_ON_ERROR If set, iconv_mime_decode() attempts to continue to process the given header even though an error occurs.

The optional charset parameter specifies the character set to represent the result by. If omitted, iconv.internal_charset will be used.

                       0, "ISO-8859-1");
