In the provided PHP code snippet, what improvements or best practices can be suggested for handling IMAP functions more efficiently?

One improvement for handling IMAP functions more efficiently is to minimize the number of times the connection to the mail server is established and closed. This can be achieved by reusing the same connection for multiple operations instead of opening and closing it for each action. Additionally, using IMAP functions that support batch operations can help reduce the number of requests sent to the server. 

// Establish a connection to the mail server
$imapStream = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password');

// Check if the connection was successful
if (!$imapStream) {
    die('Failed to connect to mail server');
}

// Perform multiple operations on the same connection
// For example, fetch emails, mark them as read, and delete them

// Close the connection after all operations are done
imap_close($imapStream);
