一、index.php
//错误显示，如果注掉就不显示错误
error_reporting(E_ALL | E_STRICT);
//基本目录，一些模板目录中使用
defined('BASE_PATH')
|| define('BASE_PATH', realpath(dirname(__FILE__)));
// 定义应用目录
defined('APPLICATION_PATH')
|| define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/application'));
// 定义应用环境，APPLICATION_ENV是预设的系统环境变量，它将用于Application.ini中区分应用程序运行环境，这里预设3个值：development, testing, production，分别表示开发环境，测试环境及实际运行环境
defined('APPLICATION_ENV')
|| define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));
// 确认ZF的库
set_include_path(implode(PATH_SEPARATOR, array(
realpath(APPLICATION_PATH . '/../library'),
'E:/apmserv/APMServ5.2.6/www/htdocs/haojie_xml/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'
);
/*
Zend_Application（）用于解析application.ini，用APPLICATION_ENV来指定读取application.ini的那个模块（比如product）
*/
$application->bootstrap()
->run();
二.application.ini
[production]
;=========== php ini配置
phpSettings.display_startup_errors = 0
phpSettings.display_errors = 0
;=========== 库文件路径
;includePaths.library = APPLICATION_PATH "/../library"
;=========== 类自动加载的前缀
autoloaderNamespaces.0 = "Digitalus_"
;=========== bootstrap类的路径及类名
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
;=========== 自定义资源的路径及其前缀
;pluginPaths.Kbs_Application_Resource = APPLICATION_PATH "/../library/Kbs/Application/Resource/"
;=========== front controller配置
;resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.env = APPLICATION_ENV
resources.frontController.throwExceptions = false
resources.frontController.defaultModule = "admin"
resources.frontController.defaultControllerName = "index"
resources.frontController.defaultAction = "index"
;============启动的时候会自动加载下面的类
resources.frontController.plugins.init = "Digitalus_Controller_Plugin_Initializer"
resources.frontController.plugins.init = "Digitalus_Controller_Plugin_Auth"
[staging : production]
[testing : production]
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
[development : production]
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
三。Bootstrap.php
protected function _initAutoload()
{
// Ensure front controller instance is present
$this->bootstrap('frontController');
// Get frontController resource
$this->_front = $this->getResource('frontController');
// Add autoloader empty namespace
$autoLoader = new Zend_Loader_Autoloader_Resource(array(
'basePath' => APPLICATION_PATH,
'namespace' => '',
'resourceTypes' => array(
'form' => array(
'path' => 'admin/forms/',
'namespace' => 'Admin_Form_',
),
'model' => array(
'path' => 'models/', //模块路径
'namespace' => 'Model_' //制定默认模块前缀
),
),
));
// Return it, so that it can be stored by the bootstrap
return $autoLoader;
}
1。加载xml文件
protected function _initConfig()
{
$config = new Zend_Config_Xml(APPLICATION_PATH . '/data/config.xml', APPLICATION_ENV);
// 注册$config
$registry = Zend_Registry::getInstance();
$registry->set('config', $config);
// Return it, so that it can be stored by the bootstrap
return $config;
}
2。连接数据库
protected function _initDb()
{
$this->bootstrap('config');
// Get config resource
$config = $this->getResource('config');
// Setup database
$db = Zend_Db::factory($config->database->adapter, $config->database->toArray());
$db->setFetchMode(Zend_Db::FETCH_OBJ);
$db->query("SET NAMES 'utf8'");
$db->query("SET CHARACTER SET 'utf8'");
Zend_Db_Table::setDefaultAdapter($db);
// Return it, so that it can be stored by the bootstrap
return $db;
}
3。初始化Controller
protected function _initControllers()
{
$this->_front->addControllerDirectory(APPLICATION_PATH . '/admin/controllers', 'admin');
}
3。加载缓存，以文件的形式在服务器上保存，减少对数据库和服务器的压力
protected function _initCache()
{
// Cache options
$frontendOptions = array(
'lifetime' => 1200, // Cache lifetime of 20 minutes
'automatic_serialization' => true,
);
$backendOptions = array(
'lifetime' => 3600, // Cache lifetime of 1 hour
'cache_dir' => BASE_PATH . '/cache/', // Directory where to put the cache files
);
// Get a Zend_Cache_Core object
$cache = Zend_Cache::factory('Core', 'File', $frontendOptions, $backendOptions);
Zend_Registry::set('cache', $cache);
// 查看一个缓存是否存在:
if(!$result = $cache->load('myresult')) {
// 缓存不命中
$cache->save('aaaaaaaaaaaaaa', 'myresult');
} else {
// cache hit! shout so that we know
echo "This one is from cache!/n/n";
}
// Return it, so that it can be stored by the bootstrap
return $cache;
}
$cache = Zend_Registry::get('cache');
if(!$result = $cache->load('myresult')) {
$cache->save('indexAction', 'myresult');
} else {
echo $cache->load('myresult');
$cache->remove('myresult'); //删除缓存
}
四。在TrafficLog.php中有日期格式化的例子
$date = new Zend_Date();
$data['timestamp'] = $date->get(zend_date::TIMESTAMP);
$data['day'] = $date->get(zend_date::WEEKDAY_DIGIT);
$data['week'] = $date->get(zend_date::WEEK);
$data['month'] = $date->get(zend_date::MONTH);
$data['year'] = $date->get(zend_date::YEAR);
$data['page'] = $_SERVER['REQUEST_URI'];
$data['ip'] = $_SERVER['REMOTE_ADDR'];
