Retrieve email address from imap header - php

Question

I'm using php imap function imap_header to extract full header and imap_fetch_overview to extract raw header. Both the functions gives me stdClass object and arrays respectively.
I would like to always clean my from and to before further processing. Sometimes a FROM or TO can contain some thing like this,
Test user <test#test.com>
Also currently in my FROM I only see Test User and no email address until I use firebug.
How do I just get the test#test.com from these objects, arrays?
This is the result I get from imap_fetch_overview
Array
(
[0] => stdClass Object
(
[subject] => Testing
[from] => Test User
[to] => testuser2#test.com
[date] => Wed, 17 Apr 2013 18:43:46 +0530
[message_id] => <abcdef1244.93784jgsfk#test.com>
[size] => 3443
[uid] => 1234
[msgno] => 123
[recent] => 0
[flagged] => 0
[answered] => 0
[deleted] => 0
[seen] => 0
[draft] => 0
[udate] => 1366204439
)
)
There is a hidden <test#test.com> next to Test User. How do I extract that email address?
Similarly this is what I get from imap_header
stdClass Object
(
[date] => Wed, 17 Apr 2013 18:43:46 +0530
[Date] => Wed, 17 Apr 2013 18:43:46 +0530
[subject] => Test
[Subject] => Test
[message_id] => <abcdef1244.93784jgsfk#test.com>
[toaddress] => testuser#test.com
[to] => Array
(
[0] => stdClass Object
(
[mailbox] => testuser
[host] => test.com
)
)
[fromaddress] => Test User
[from] => Array
(
[0] => stdClass Object
(
[personal] => Test User
[mailbox] => test
[host] => test.com
)
)
[reply_toaddress] => Test User
[reply_to] => Array
(
[0] => stdClass Object
(
[personal] => Test User
[mailbox] => test
[host] => test.com
)
)
[senderaddress] => Test User
[sender] => Array
(
[0] => stdClass Object
(
[personal] => Test User
[mailbox] => test
[host] => test.com
)
)
[Recent] =>
[Unseen] => U
[Flagged] =>
[Answered] =>
[Deleted] =>
[Draft] =>
[Msgno] => 123
[MailDate] => 17-Apr-2013 13:13:59 +0000
[Size] => 3443
[udate] => 1366204439
)
A preg_match would be the obvious answer but just cant seem to figure out how to perform it on from bit where email address is not seen in the browser but is present when inspected with firebug. Any help is appreciated.
Thanks.

Answer 1

You can go one step further with imap_rfc822_parse_adrlist()Docs:
$toAddresses = imap_rfc822_parse_adrlist('Test user <test#test.com>', 'localhost');
print_r($toAddresses);
Array
(
[0] => stdClass Object
(
[mailbox] => test
[host] => test.com
[personal] => Test user
)
)

Answer 2

If name of array of std object is $arr
$arr[0]->to
returns what you want.
in second case
$stdObject <- object that is returned by second function
foreach($stdObject->to as $to)
{
echo $to->mailbox;
echo $to->host;
}

I've just discovered this thread and whilst it's old I hope this comment might help. I believe I've answered the query. As it happens, the format of the sender email is what's causing the issue.
From Name <from#name.com>
Because of the <> tag, the browser is making it into an HTML tag, I guess something akin to a span. By using str_replace to change "<" into " " (or whatever) you remove the issue before it gets to HTML
