iconv_mime_decode_headers — Decodes multiple MIME header fields at once
Description
$encoded_headers
[, int $mode = 0
[, string $charset = ini_get("iconv.internal_encoding")
]] )Decodes multiple MIME header fields at once.
Parameters
-
encoded_headers -
The encoded headers, as a string.
-
mode -
modedetermines 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
charsetparameter specifies the character set to represent the result by. If omitted, iconv.internal_encoding will be used.
Return Values
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.
Examples
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>;

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:

If you need lower-case header-names (as I read the documentation case is not guranteed) try something like
<?php
$headers_string = <<<EOF
Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=
To: example@example.com
Date: Thu, 1 Jan 1970 00:00:00 +0000

$headers = array_combine(array_map("strtolower", array_keys($headers)), array_values($headers));
