iconv_mime_decode_headers

(PHP 5)

iconv_mime_decode_headers — Decodes multiple MIME header fields at once

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.

Parameters

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.

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>;
    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_string0"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 ) )
