Memcached Figure 1. The Memcached client library is responsible for sending requests to the correct servers. Step 1: Application requests keys foo, bar and baz using the client library, which calculates key hash values, determining which Memcached server should receive requests. Step 2: Memcached client sends parallel requests to all relevant Memcached servers. Step 3: Memcached servers send responses to the client library. Step 4: Memcached client library aggregates responses for the application. Install Memcache with Drupal: Windows XP: a. Install the Memcached Service Download memcached binaries for Win32 from http://jehiah.cz/projects/memcached-win32/ Unzip the binaries in a directory (eg. c:\memcached) Run the command “c:\memcached\memcached.exe -d install” for installing the service.

The following list provides the main new features: public / private / protected: Access modifiers for methods and properties. Allows the use of common OO access modifiers to control access to methods and properties: class MyClass { private $id = 18; public function getId() { return $this->id; } } Unified constructor name __construct(): Instead of the constructor being the name of the class, it is now declared as __construct() , which makes it easier to shift classes inside class hierarchies: class MyClass { function __construct() { print "Inside constructor"; ...
Here is a list of KernelEvents constants: KernelEvents::CONTROLLER ; // The CONTROLLER event occurs once a controller was found for handling a request. KernelEvents::EXCEPTION ; // The EXCEPTION event occurs when an uncaught exception appears. KernelEvents::FINISH_REQUEST ; //The FINISH_REQUEST event occurs when a response was generated for a request. KernelEvents::REQUEST ; // The REQUEST event occurs at the very beginning of request dispatching. KernelEvents::RESPONSE ; // The RESPONSE event occurs once a response was created for replying to a request. KernelEvents::TERMINATE ; // The TERMINATE event occurs once a response was sent. KernelEvents::VIEW ; // The VIEW event occurs when the return value of a controller is not a Response instance.
