php phalcon项目实战
Phalcon是一套实现MVC架构的高性能PHP应用程序框架。初始版本发布于2012年11月，开放源代码并基于BSD授权条款。与其他大部分的PHP框架不同，Phalcon是以扩充的方式以C语言所编写，因此Phalcon的执行速度高过其他PHP框架，并且消耗更少的资源，根据官方的测试，Phalcon是目前世界上速度最快的PHP框架之一。最近使用phalcon和之前的模板进行搭建了简单的项目，下面一起分享下该框架是怎样搭建项目：
该项目中是一个多模板项目：phalcon中session，db，第三方类库扩展，验证码，分页等都涉及到，请参阅代码。
1，首先我们需要详细了解阅读phalcon提供的api文档，目前使用的phalcon版本是1.3
2，我们搭建的该项目(该项目是多模块)中public/index.php是非常重要的引导文件（入口），由于phalcon是c开发的一个框架，我们是需要注册各种组件，调用其框架的所需接口，常见的如session,db,router,url等等
如下，这是我在项目中使用的index.php：
<?php
use Phalcon\Mvc\Application;
error_reporting(E_ALL);
ini_set('date.timezone','Asia/Shanghai');
try {
$loader = new \Phalcon\Loader();
$loader->registerNamespaces(array(
"Phalcon_wifi\Common\Models" => "../apps/Common/models",
"Phalcon_wifi\Common\Controllers" => "../apps/Common/controllers",
"Phalcon_wifi\Common\Config" => "../apps/Common/config",
"Phalcon_wifi\Common\Ext" => "../apps/Common/ext",
));
$loader->register();
$di = new \Phalcon\DI\FactoryDefault();
$di["router"] = function () {
$router = new \Phalcon\Mvc\Router();
$router->setDefaultModule("Admin");
$router->setDefaultNamespace("Phalcon_wifi\Admin\Controllers");
$router->add('/:controller/:action/:params', array(
'module' => 'Admin',
'controller' => 1,
'action' => 2,
'params' => 3
))->setName("common");
return $router;
};
$di["url"] = function () use ($di) {
$url = new \Phalcon\Mvc\Url();
$url->setBaseUri($di->get("config")->get("common")["baseuri"]);
return $url;
};
$di["session"] = function () {
$session = new \Phalcon\Session\Adapter\Files();
$session->start();
return $session;
};
$di["db"] = function () use($di) {
$config = $di->get("config")->get("common")["db"];
$connection = new \Phalcon\Db\Adapter\Pdo\Mysql(array(
"host" => $config["host"],
"username" => $config["username"],
"password" => $config["password"],
"dbname" => $config["dbname"],
"charset" => $config["charset"]
));
$eventsManager = new \Phalcon\Events\Manager();
$dblog = $di->get("config")->get("common")["dblog"];
$logger = new \Phalcon\Logger\Adapter\File(__DIR__ . $dblog);
$eventsManager->attach('db:beforeQuery', function($event, $connection) use ($logger) {
$sqlVariables = $connection->getSQLVariables();
if (count($sqlVariables)) {
$logger->log($connection->getSQLStatement() . ' ' . join(', ', $sqlVariables), \Phalcon\Logger::INFO);
} else {
$logger->log($connection->getSQLStatement(), \Phalcon\Logger::INFO);
}
});
$connection->setEventsManager($eventsManager);
return $connection;
};
$di["dbBackupTool"] = function () use($di) {
$config = $di->get("config")->get("common")["db"];
return new \Phalcon_wifi\Common\Ext\DBManager($config["username"], $config["password"], $config["host"], $config["dbname"]);
};
$di["validateCodeCreator"] = function () use($di) {
return new \Phalcon_wifi\Common\Ext\ValidateCode($di->get('session'));
};
$di["config"] = function () {
$config = new \Phalcon_wifi\Common\Config\Config;
return $config->config;
};
$di->set('modelsManager', function() {
return new Phalcon\Mvc\Model\Manager();
});
$application = new Application($di);
$application->registerModules(array(
"Admin" => array(
"className" => "Phalcon_wifi\Admin\Module",
"path" => __DIR__ . "/../apps/Admin/Module.php"
),
"Portal" => array(
"className" => "Phalcon_wifi\Portal\Module",
"path" => __DIR__ . "/../apps/Portal/Module.php"
)
));
echo $application->handle()->getContent();
} catch (Exception $e) {
echo $e->getMessage();
}
上述代码中config，是单独放在一个文件apps/common/config/config.php如下：
<?php
namespace Phalcon_wifi\Common\Config;
class Config {
public $config;
public function __construct() {
//module对应整型数值
$configs["common"]["modules"] = array("Admin" => 1, "Brand" => 2, "Agent" => 3, "Merchant" => 4);
//缓存文件夹
$configs["common"]["application"] = array('cacheDir' => __DIR__ . '/../cache/');
//不需要进行登陆验证的url()
$configs["common"]["not_check_uri"] = array("Admin/Members/login", "Admin/Index/getValidateCode", "Admin/Index/test", "Admin/Members/confirmLogin");
//常用的静态数据
$configs["common"]["config_setting"] = [
"group" => [
1=>"图片配置",
2=>"路由器配置",
3=>"短信网关配置",
4=>"邮件配置",
5=>"系统配置"
],
"type" => [
1=>"字符",
2=>"文本",
3=>"数组",
4=>"枚举",
5=>"密码",
6=>"长文本",
7=>"加长文本",
8=>"数字"
]
];
//系统版本
$configs["common"]["version"] = "0.0.1";
//数据库配置
$configs["common"]["db"] = [
"host" => "XXXXXX",
"username" => "XXXX",
"password" => "xxxxxxx",
"dbname" => "xxxxxxxx",
"charset" => "utf8"
];
//数据库备份文件名
$configs["common"]["dblog"] = "/../apps/Common/logs/db_" . date("Y_m_d_H") . ".log";
//app baseuri
$configs["common"]["baseuri"] = "/project_wifi/phalcon_wifi/";
$this->config = new \Phalcon\Config($configs);
}
}
具体的项目代码，数据库文件，api文档进行打包，有兴趣的进行下载进行参考，有好的想法，见解，请给出宝贵的意见，运行该项目请修改apps/common/config/config.php中的baseUri，每个人的项目可能不一样。
