이 기사의 예에서는 Zend Framework 튜토리얼의 애플리케이션 사용법을 설명합니다. 참고할 수 있도록 모든 사람과 공유하세요. 자세한 내용은 다음과 같습니다.
Zend_Application은 Zend Framework의 핵심 구성 요소입니다. Zend_Application은 Zend Framework 애플리케이션에 대한 기본 기능을 제공하며 프로그램의 진입점입니다. 주요 기능은 PHP 환경 로드 및 구성(자동 로드 포함)과 애플리케이션 부팅의 두 가지입니다.
일반적으로 Zend_Application 생성자는 구성 옵션을 통해 구성되지만 사용자 지정 방법을 사용하여 완전히 구성할 수도 있습니다. 아래에는 두 가지 사용 사례가 있습니다.
Zend_Application 구성 옵션
생성자:
/**
* Constructor
*
* Initialize application. Potentially initializes include_paths, PHP
* settings, and bootstrap class.
*
* @param string $environment
* @param string|array|Zend_Config $options String path to configuration file, or array/Zend_Config of configuration options
* @throws Zend_Application_Exception When invalid options are provided
* @return void
*/
public function __construct($environment, $options = null)
{
$this->_environment = (string) $environment;
require_once 'Zend/Loader/Autoloader.php';
$this->_autoloader = Zend_Loader_Autoloader::getInstance();

if (is_string($options)) {
$options = $this->_loadConfig($options);
} elseif ($options instanceof Zend_Config) {
$options = $options->toArray();
} elseif (!is_array($options)) {
throw new Zend_Application_Exception('Invalid options provided; must be location of config file, a config object, or an array');
}
$this->setOptions($options);
}
