You can using Define save on define.php include for next time use on other project This is PROTOCOL DOMAIN PORT SITE_ROOT AND SITE PATH

**
 * domain
 * ex: localhost, maskphp.com, demo.maskphp.com,...
 */
define('DOMAIN', isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : $_SERVER['SERVER_NAME']);

/**
 * protocol
 * ex: http, https,...
 */
define('PROTOCOL', isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] === 'on' || $_SERVER['HTTPS'] === 1)
    || isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https' ? 'https' : 'http');

/**
 * port
 * ex: 80, 8080,...
 */
define('PORT', $_SERVER['SERVER_PORT']);

/**
 * site path
 * ex: http://localhost/maskphp/ -> /maskphp/
 */
define('SITE_PATH', preg_replace('/index.php$/i', '', $_SERVER['PHP_SELF']));

/**
 * site root
 * ex: http://maskgroup.com, http://localhost/maskphp/,...
 */
define('SITE_ROOT', PROTOCOL . '://' . DOMAIN . (PORT === '80' ? '' : ':' . PORT) . SITE_PATH);
