Demonstrates how to setup an SSH tunnel for IMAP.

use chilkat;

$imap = new chilkat::CkImap();

#  Anything unlocks the component and begins a fully-functional 30-day trial.
$success = $imap->UnlockComponent("Anything for 30-day trial");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Connect to an SSH server and establish the SSH tunnel:

#  The SSH hostname may be a hostname or an
#  IP address, such as "192.168.1.108".
#  The port is typically 22 (the standard port for SSH).
$sshHostname = "www.mysshserver.com";
$sshPort = 22;
$success = $imap->SshTunnel($sshHostname,$sshPort);
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Authenticate with the SSH server via a login/password
#  or with a public key.
#  This example demonstrates SSH password authentication.
#  Note: This is not authenticating with the IMAP server, it is
#  for authenticating with the SSH server, which is separate.
$success = $imap->SshAuthenticatePw("mySshLogin","mySshPassword");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  OK, the SSH tunnel is setup.  The IMAP component may
#  be used exactly the same as usual, except all communications
#  are sent through the SSH tunnel.

#  Connect to an IMAP server via the SSH tunnel.
#  Because the SSH tunnel has been previously setup,
#  this does not establish a direct connection with the IMAP
#  server.  It directs the SSH server to establish the connection.
$success = $imap->Connect("mail.chilkatsoft.com");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Authenticate with the IMAP server via the SSH tunnel.
$success = $imap->Login("myLogin","myPassword");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Select an IMAP mailbox
$success = $imap->SelectMailbox("Inbox");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  We can choose to fetch UIDs or sequence numbers.
$fetchUids = 1;
#  Get the message IDs of all the emails in the mailbox
# messageSet is a CkMessageSet
$messageSet = $imap->Search("ALL",$fetchUids);
if ($messageSet eq null ) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Fetch the emails into a bundle object:

# bundle is a CkEmailBundle
$bundle = $imap->FetchBundle($messageSet);
if ($bundle eq null ) {

    print $imap->lastErrorText() . "\n";
    exit;
}

#  Loop over the bundle and display the FROM and SUBJECT of each.

for ($i = 0; $i <= $bundle->get_MessageCount() - 1; $i++) {

    # email is a CkEmail
    $email = $bundle->GetEmail($i);
    print $email->ck_from() . "\r\n";
    print $email->subject() . "\r\n";
    print "--" . "\r\n";

}

#  Disconnect from the IMAP server.
$imap->Disconnect();
