// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Imap')
$imap = new COM("Chilkat.Imap");

// Connect to an IMAP server.
// Use TLS
$imap->Ssl = 1;
$imap->Port = 993;
$success = $imap->Connect('imap.someMailServer.com');
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

// Login
$success = $imap->Login('myLogin','myPassword');
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

// Check the capabilities of the IMAP server.
$cap = $imap->capability();
print 'IMAP capabilities: ' . $cap . "\n";

// If the capabilities string contains the substring "UIDPLUS", then 
// the UID of the appended email will be available in the AppendUid property (see below).

// For example, the GMail IMAP server has these capabilities (at this current time)
// * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN 
// X-GM-EXT-1 UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT 
// APPENDLIMIT=35882577 LIST-EXTENDED LIST-STATUS

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Email')
$email = new COM("Chilkat.Email");

// Load the email from a .eml file.
$success = $email->LoadEml('myEmail.eml');
if ($success != 1) {
    print $email->LastErrorText . "\n";
    exit;
}

$success = $imap->AppendMail('Inbox',$email);
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

// If the IMAP server supports the UIDPLUS extension, then the 
// imap.AppendUid will contain the UID of the appended email.
// Otherwise AppendUid will be 0.
print 'UID of appended email: ' . $imap->AppendUid . "\n";

// If the IMAP server does NOT have UIDPLUS, then a program can 
// first select the mailbox, get the value of the UidNext property,
// and then append.  The appended email SHOULD have a UID equal to 
// the UidNext that was obtained just prior to appending (assuming no other
// program is simultaneously appending an email to the same mailbox).

// Note: It is not required to select a mailbox to append.  The select is only
// done for the purpose of obtaining the UIDNEXT value.
$success = $imap->SelectMailbox('Inbox');
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

$uidNext = $imap->UidNext;

$success = $imap->AppendMail('Inbox',$email);
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

print 'The UID of the appended email SHOULD be ' . $uidNext . "\n";

print 'Email uploaded to Inbox!' . "\n";

// Disconnect from the IMAP server.
$success = $imap->Disconnect();
