What best practices can be implemented to prevent a 500 error after a failed IMAP connection in PHP?

When an IMAP connection fails in PHP, it can result in a 500 error if not properly handled. To prevent this, you can use try-catch blocks to catch any exceptions thrown during the connection attempt and handle them gracefully, such as by logging the error or displaying a user-friendly message. 

try {
    $imap = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password');
    
    // Do something with the IMAP connection
    
    imap_close($imap);
} catch (Exception $e) {
    error_log('IMAP connection error: ' . $e->getMessage());
    echo 'An error occurred while connecting to the IMAP server. Please try again later.';
}
