imap_mime_header_decode
Description
array imap_mime_header_decode ( string text)imap_mime_header_decode() function decodes MIME message header extensions that are non ASCII text (see RFC2047) The decoded elements are returned in an array of objects, where each object has two properties, "charset" & "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".
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.
