# iconv_mime_decode_headers

(PHP 5)

iconv_mime_decode_headers — Decodes multiple MIME header fields at once

### Opis

array iconv_mime_decode_headers ( string `$encoded_headers` [, int `$mode` = 0 [, string `$charset` = ini_set("iconv.internal_encoding") ]] )

Decodes multiple MIME header fields at once.

### Parametry

`encoded_headers`

  The encoded headers, as a string.

`mode`

  `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.

  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.

`charset`

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

### Zwracane wartości

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.
