mode
determines the behaviour in the event iconv_mime_decode_headers() encounters a malformedMIME
header field. You can specify any combination of the following bitmasks.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. -
encoding
-
The optional
encoding
parameter specifies the character set to represent the result by. If omitted ornull
, iconv.internal_encoding will be used.
Rückgabewerte
Returns an associative array that holds a whole set of
MIME
header fields specified by
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. Note that header names are not case-insensitive.
