Description
array
iconv_mime_decode_headers ( string encoded_headers [, int mode [, string charset]] )
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.
Example 1. iconv_mime_decode_headers() example
<?php
$headers_string = <<<EOF
Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=
To: example@example.com
Date: Thu, 1 Jan 1970 00:00:00 +0000
Message-Id: <example@example.com>
Received: from localhost (localhost [127.0.0.1]) by localhost
with SMTP id example for <example@example.com>;
Thu, 1 Jan 1970 00:00:00 +0000 (UTC)
(envelope-from example-return-0000-example=example.com@example.com)
Received: (qmail 0 invoked by uid 65534); 1 Thu 2003 00:00:00 +0000
EOF;
$headers = iconv_mime_decode_headers($headers_string, 0, "ISO-8859-1");
print_r($headers);
?>
|
The above example will output: Array
(
[Subject] => Prüfung Prüfung
[To] => example@example.com
[Date] => Thu, 1 Jan 1970 00:00:00 +0000
[Message-Id] => <example@example.com>
[Received] => Array
(
[0] => from localhost (localhost [127.0.0.1]) by localhost with SMTP id example for <example@example.com>; Thu, 1 Jan 1970 00:00:00 +0000 (UTC) (envelope-from example-return-0000-example=example.com@example.com)
[1] => (qmail 0 invoked by uid 65534); 1 Thu 2003 00:00:00 +0000
)
