About

Zend Framework 2 is an open source framework for developing web applications and services using PHP 5.3+.

Zend Framework 2 uses 100% object-oriented code and utilises most of the new features of PHP 5.3, namely namespaces, late static binding, lambda functions and closures.

Composer

Composer is a tool for dependency management in PHP.

It deals with "packages" or libraries, but it manages them on a per-project basis, installing them in a directory (e.g. vendor) inside your project.

The problem that Composer solves is this:You have a project that depends on a number of libraries.Some of those libraries depend on other libraries.You declare the things you depend on.Composer finds out which versions of which packages need to be installed, and installs them

RoutingRouting is the act of matching a request to a given controller.

Routes are stored in the “module.config.php” file found in the config directory. In this file you can modify existing routes and add new routes.

Session Management

Zend Framework 2

The session manager is a class that is responsible for all aspects of session management. It initializes and configures configuration, storage and save handling.Usage: In module Controller class:Use Zend\Session\Container;

In Action:$session = new Container('User');//to set session $session->offsetSet('UserName', 'Demo User');//get session$session->offsetGet('UserName');//session exist check$session->offsetExists('UserName');//destory session$session->offsetUnset('UserName');

CSS Stylesheets and Twitter Bootstrap

This is provided by default in ZF2 framework skeleton application.

Bootstrap has became a popular CSS framework, allowing to make your web site professionally looking and visually appealing, even if you don’t have advanced designer skills and without the need of creating basic CSS rules (but, of course you can define your own custom CSS rules on top of Bootstrap to customise your site’s appearance). Bootstrap is freely distributed under the Apache License v.2.0.

Zend Framework 2

Cont...Generally, the Bootstrap does the following things:

• It provides the CSS reset that is a style sheet defining styles for all possible HTML elements. This ensures your web site will look the same way in all web browsers.• It provides the base CSS rules that define style of typography (headings and text), tables, forms, buttons, images and so on.• It defines the grid system. The grid system allows to arrange elements on your web page in a grid-like structure. • It defines useful web interface components like dropdown menus, navigation bars, breadcrumbs, pagination and so on. • It includes the JavaScript extensions that allow to make Bootstrap-provided interface components more interactive. For example, JavaScript is used to animate dropdown menus and display “modal dialogs”.
