// In the IMAP (Internet Message Access Protocol) protocol, criteria strings are used to search for emails matching specific criteria on the mail server. 
// When searching for emails by date, you can use criteria strings to specify the date range you're interested in.
// 
// IMAP provides several options for searching emails by date using criteria strings. Here are the commonly used ones:
// 
// 1. BEFORE: Searches for emails sent before a specific date.
//    Example: BEFORE 01-Apr-2022
// 
// 2. ON: Searches for emails sent on a specific date.
//    Example: ON 01-Apr-2022
// 
// 3. SINCE: Searches for emails sent after a specific date.
//    Example: SINCE 01-Apr-2022
// 
// 4. SENTBEFORE: Searches for emails whose date header (sent date) is before a specific date.
//    Example: SENTBEFORE 01-Apr-2022
// 
// 5. SENTON: Searches for emails whose date header (sent date) is on a specific date.
//    Example: SENTON 01-Apr-2022
// 
// 6. SENTSINCE: Searches for emails whose date header (sent date) is after a specific date.
//    Example: SENTSINCE 01-Apr-2022
// 

// 
// The date format used in IMAP criteria strings is typically a specific format like "DD-Mon-YYYY" (e.g., "01-Apr-2022"), but some servers may also accept other formats 
// such as "YYYY-MM-DD". It's essential to check the documentation or specifications of the IMAP server you're working with to ensure compatibility with the 
// date format you're using.
// 
// By combining these date criteria strings with other search criteria (such as sender, recipient, subject, etc.), 
// you can effectively filter and retrieve emails based on various conditions.
// 

// Search for messages on a specific date.
// The date string is DD-Month-YYYY where Month is
// Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec.
$onDate = 'SENTON 15-Apr-2024';

// Search for messages between two dates.  SENTBEFORE
// finds emails sent before a date, and SENTSINCE finds
// email sent on or after a date.  The "AND" operation
// is implied by joining criteria, separated by spaces.
$betweenDates = 'SENTSINCE 12-Apr-2024 SENTBEFORE 15-Apr-2024';

// We can choose to fetch UIDs or sequence numbers.
$fetchUids = true;
// messageSet is a CkMessageSet
$messageSet = $imap->Search($betweenDates,$fetchUids);
if ($imap->get_LastMethodSuccess() == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

print $messageSet->toCompactString() . "\n";

// Download each email in the message set.

$messageCount = $messageSet->get_Count();
$i = 0;
while ($i < $messageCount) {
    // email is a CkEmail
    $email = $imap->FetchSingle($messageSet->GetId($i),$fetchUids);
    if ($imap->get_LastMethodSuccess() == false) {
        print $imap->lastErrorText() . "\n";

        exit;
    }

    print $email->subject() . "\n";
    // ...

    $i = $i + 1;
}

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