=?ISO-8859-1 in mail subject

Question

I'm acquiring the unread mails I have in my GMail account through PHP and its method *imap_open*

When I get the subjects through the method *imap_fetch_overview* I get some subjects like this:

=?ISO-8859-1?Q?Informaci=F3n_Apartamento_a_la_Venta?= =?ISO-8859-1?Q?_en_Benasque(Demandas:_0442_______)?=

It's unreadable, I think because of its character encoding.

What should I do to make it readable?

Answer 1

http://php.net/manual/en/function.mb-decode-mimeheader.php

Answer 2

To get the string in UTF-8, do:

$or = '=?ISO-8859-1?Q?Informaci=F3n_Apartamento_a_la_Venta?= =?ISO-8859-1?Q?_en_Benasque(Demandas:_0442_______)?=';
mb_internal_encoding('UTF-8');
$v = str_replace("_"," ", mb_decode_mimeheader($or));

which gives:

Información Apartamento a la Venta en Benasque(Demandas: 0442       )

You can then convert to ISO-8859-1, if you wish.
