What should I share for the first time? Let's start with zf's entry file.

The entry file, the index.php file under public, can be directly pasted to the manually created one.

header("Content-Type: text/html; charset=UTF-8");
error_reporting(E_ALL|E_STRICT);
date_default_timezone_set('Asia/Shanghai');
// Define path to application directory
defined('APPLICATION_PATH')
 || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));

// Define application environment
defined('APPLICATION_ENV' )
 || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
 realpath(APPLICATION_PATH . '/../library'),
 get_include_path(),
)));


/**Zend_Application*/
require_once 'Zend/Application.php';
// Create application , bootstrap, and run
$application = new Zend_Application(
 APPLICATION_ENV,
 APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()
 ->run();
