Updated calls to resource cleanup functions (curl_close, imagedestroy, finfo_close) to only execute for PHP versions below 8.0, as these functions have no effect in PHP 8+. Improved error handling and connection management in mysqli and sqlite drivers, and added missing DOCTYPE in error output for better HTML compliance.
