// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$imapSrc = new CkImap();

// Connect to our source IMAP server.
$success = $imapSrc->Connect('imap.someMailServer.com');
if ($success != true) {
    print $imapSrc->lastErrorText() . "\n";
    exit;
}

// Login to the source IMAP server
$success = $imapSrc->Login('admin@chilkatsoft.com','myPassword');
if ($success != true) {
    print $imapSrc->lastErrorText() . "\n";
    exit;

// Connect to our destination IMAP server.
$success = $imapDest->Connect('mail.example-code.com');

// Login to the destination IMAP server
$success = $imapDest->Login('myLogin','myPassword');

// Select an IMAP mailbox on the source IMAP server
$success = $imapSrc->SelectMailbox('Inbox');
if ($success != true) {
    print $imapSrc->lastErrorText() . "\n";
    exit;
}

// After selecting a mailbox, the NumMessages property will
// be updated to reflect the total number of emails in the mailbox:
print $imapSrc->get_NumMessages() . "\n";

// The emails in the mailbox will always have sequence numbers
// ranging from 1 to NumMessages.

// This example will copy the first 10 messages.
// We'll leave it up to you to write code to copy
// the entire sequence range in reasonable size chunks.
$startSeqNum = 1;
$msgCount = 10;

// sa is a CkStringArray
$sa = $imapSrc->FetchSequenceAsMime($startSeqNum,$msgCount);
if ($imapSrc->get_LastMethodSuccess() != true) {
    print $imapSrc->lastErrorText() . "\n";
    exit;
}

for ($i = 0; $i <= $sa->get_Count() - 1; $i++) {
    $success = $imapDest->AppendMime('Inbox',$sa->getString($i));
    if ($success != true) {
        print $imapDest->lastErrorText() . "\n";
        exit;
    }

}

// Disconnect from the IMAP servers.
$success = $imapSrc->Disconnect();
$success = $imapDest->Disconnect();
