(PHP 4, PHP 5)
imap_mime_header_decode — Decode MIME header elements
$text
)Decodes MIME message header extensions that are non ASCII text (see » RFC2047).
text
The MIME text
The decoded elements are returned in an array of objects, where each object has two properties, charset and text.
If the element hasn't been encoded, and in other words is in plain US-ASCII, the charset property of that element is set to default.
Example #1 imap_mime_header_decode() example
<?php
$text = "=?ISO-8859-1?Q?Keld_J=F8rn_Simonsen?= <keld@example.com>";
$elements = imap_mime_header_decode($text);
for ($i=0; $i<count($elements); $i++) {
echo "Charset: {$elements[$i]->charset}\n";
echo "Text: {$elements[$i]->text}\n\n";
}
?>
以上例程会输出：
Charset: ISO-8859-1 Text: Keld Jørn Simonsen Charset: default Text: <keld@example.com>
In the above example we would have two elements, whereas the first element had previously been encoded with ISO-8859-1, and the second element would be plain US-ASCII.
