iconv_mime_decode_headers
(PHP 5)
iconv_mime_decode_headers — Decodes multiple MIME header fields at once
说明
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.
参数
- 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.
范例
Example#1 iconv_mime_decode_headers() example
<?php
$headers_string = <<<EOF
Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=
To: [email protected]
Date: Thu, 1 Jan 1970 00:00:00 +0000
Message-Id: <[email protected]>
Received: from localhost (localhost [127.0.0.1]) by localhost
with SMTP id example for <[email protected]>;
Thu, 1 Jan 1970 00:00:00 +0000 (UTC)
(envelope-from [email protected])
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);
?>
上例将输出：
Array ( [Subject] => Prüfung Prüfung [To] => [email protected] [Date] => Thu, 1 Jan 1970 00:00:00 +0000 [Message-Id] => <[email protected]> [Received] => Array ( [0] => from localhost (localhost [127.0.0.1]) by localhost with SMTP id example for <[email protected]>; Thu, 1 Jan 1970 00:00:00 +0000 (UTC) (envelope-from [email protected]) [1] => (qmail 0 invoked by uid 65534); 1 Thu 2003 00:00:00 +0000 ) )
