iconv_mime_decode — Decodes a MIME header field
Decodes a MIME header field.
The encoded header, as a string.
mode determines the behaviour in the event iconv_mime_decode() encounters a malformed MIME header field. You can specify any combination of the following bitmasks.
| 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_encoding will be used.
Returns a decoded MIME field on success, or FALSE if an error occurs during the decoding.
Beispiel #1 iconv_mime_decode() example
<?php
// This yields "Subject: Prüfung Prüfung"
echo iconv_mime_decode("Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=",
0, "ISO-8859-1");
?>
In PHP versions that have imap_mime_decode built in, it's possible to emulate the operation of this function:
<?php
function iconv_mime_decode($str, $mode=0, $charset="UTF-8")
{
$data = imap_mime_header_decode($str);
if (count($data) > 0) {
// because iconv doesn't like the 'default' for charset
$charset = ($data[0]->charset == 'default') ? 'ASCII' : $data[0]->charset;
return(iconv($charset, $charset, $data[0]->text));
}
return("");
}
?>
I've only tried to use this code snippet to decode ISO-2022-JP messages to UTF-8, but I see no reason why it shouldn't work in other cases.
