imap_mime_header_decode — Decode MIME header elements
$string
) : array|falseDecodes MIME message header extensions that are non ASCII text (see » RFC2047).
stringThe 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.
The function returns false on failure.
示例 #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.
