how to redirect http to https for any wordpress site without changed in database?

Solution:
define(‘FORCE_SSL_ADMIN’, true);
define( ‘WP_SITEURL’, ‘https://programmerlab.com’);
define( ‘WP_HOME’, ‘https://programmerlab.com’);
if ( isset( $_SERVER[‘HTTP_X_FORWARDED_PROTO’]) && ‘https’ == $_SERVER[‘HTTP_X_FORWARDED_PROTO’] ) {
$_SERVER[‘HTTPS’] = ‘on’;
}
