Symfony2之session与cookie用法小结_PHP

session操作：

1. Set Session：

public function testSetSession() {
  $session = $this->getRequest()->getSession();
  $session->set($sessionName, $sessionValue );
}

2. Get Session：

public function testGetSession() {
 $session = $this->getRequest()->getSession();
 $username = $session->get($sessionName);
}

3. Clear Session：

public function testClearSession() {
  $session = $this->getRequest()->getSession();//清除session
  $session->clear();
}

cookie操作：

1. Set Cookie

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie;
public function testSetCookie($name, $value, $expire=0){
 $response = new Response();
 $response->headers->setCookie(new Cookie($name, $value, time() + $expire));
 $response->send(); // 包括 sendHeaders()、sendContent()
}

2. Get Cookie：

public function testGetCookie() {
 $request = $this->getRequest();
 return $request->cookies->all();
}

3. Clear Cookie：

public function testClearCookie() {
 $response = new Response();
 $response->headers->setCookie(new Cookie($name, $value, -1));
 $response->send();
}

4. twig模板调用cookie：

{{ app.request.cookies.get('cookie_name') }}

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
