What is Zend Framework?
Zend Framework is an open-source, object-oriented web application framework that uses the Model-View-Controller (MVC) pattern. It was created by Zend Technologies, the company behind PHP, and is one of the most popular PHP frameworks in the world. Zend Framework provides a rich set of components that can be used to build web applications, web services, APIs, and microservices. Some of the features of Zend Framework include:
Modularity: You can use only the components you need and create your own modules.
Performance: You can optimize your application with caching, compression, and other techniques.
Security: You can protect your application from common attacks with built-in filters, validators, and encryption.
Scalability: You can handle high traffic and complex functionality with ease.
Interoperability: You can integrate with other frameworks and libraries using standard interfaces and protocols.
Documentation: You can access comprehensive and up-to-date documentation and tutorials.
Benefits of using Zend Framework
Using Zend Framework has many benefits for web developers and businesses. Some of them are:
Quality: You can rely on a well-tested and stable framework that follows PHP standards and best practices.
Productivity: You can speed up your development process with ready-made components and tools.
Maintainability: You can write clean and organized code that is easy to read and modify.
Flexibility: You can customize your application according to your needs and preferences.
Community: You can get support and feedback from a large and active community of developers and users.
How to install Zend Framework
To install Zend Framework, you need to have PHP 7.1 or higher and Composer installed on your system. Composer is a dependency manager for PHP that allows you to install and update packages easily. To install Composer, follow the instructions on https://getcomposer.org/download/.
Once you have Composer installed, you can install Zend Framework using one of the following methods:
Using the skeleton application: This is the recommended way to start a new Zend Framework project. The skeleton application provides a basic structure and configuration for your application. To create a new project using the skeleton application, run the following command in your terminal:composer create-project -s dev zendframework/skeleton-application path/to/installReplace path/to/install with the directory where you want to install your project.
Using the installer: This is an alternative way to create a new Zend Framework project. The installer allows you to choose which components you want to use in your project. To use the installer, run the following command in your terminal:composer require zendframework/zendframeworkThis will install the Zend Framework package and all its dependencies. You can then use the zf command to create and manage your project.
Using individual components: This is the most flexible way to use Zend Framework. You can install only the components you need for your project and use them with any other framework or library. To install individual components, run the following command in your terminal:composer require zendframework/component-nameReplace component-name with the name of the component you want to install. You can find the list of available components on https://docs.zendframework.com/components/.
How to create a basic Zend Framework application
In this section, we will use the skeleton application method to create a basic Zend Framework application. The application will display a simple "Hello World" message on the homepage.
Setting up the project structure
After running the composer create-project command, you should see a new directory with the following structure:
skeleton-application/ config/ autoload/ development.config.php development.config.php.dist modules.config.php ... data/ cache/ module/ Application/ config/ src/ test/ view/ Module.php public/ css/ images/ js/ index.php vendor/ .gitignore composer.json composer.lock README.md
The main directories and files are:
config/: This directory contains the configuration files for your application. You can define global settings, module settings, routes, services, and other options here.
data/: This directory contains the data files for your application. You can store cache files, logs, databases, and other files here.
module/: This directory contains the modules for your application. A module is a self-contained unit of code that provides specific functionality. You can create your own modules or use third-party modules.
vendor/: This directory contains the vendor files for your application. This is where Composer installs and updates the packages you require.
.gitignore: This file tells Git which files and directories to ignore when committing changes.
composer.json: This file defines the dependencies and metadata for your project.
composer.lock: This file records the exact versions of the packages you have installed.
README.md: This file contains information about your project.
Configuring the application
The main configuration file for your application is config/application.config.php. This file defines some basic settings such as the environment mode, the modules to load, and the paths to look for modules. You can also override or extend these settings in config/autoload/*.php files.
The default configuration file looks like this:
<?php / * Zend Framework (http://framework.zend.com/) * * @link http://github.com/zendframework/ZendSkeletonApplication for the canonical source repository * @copyright Copyright (c) 2017 Zend Technologies Ltd. (http://www.zend.com) * @license http://framework.zend.com/license/new-bsd New BSD License */ // Define environment defined('APPLICATION_ENV') define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production')); // Setup autoloading require __DIR__ . '/../vendor/autoload.php'; // Retrieve configuration $appConfig = require __DIR__ . '/application.config.php'; if (file_exists(__DIR__ . '/development.config.php')) $appConfig = Zend\Stdlib\ArrayUtils::merge($appConfig, require __DIR__ . '/development.config.php'); // Run the application Zend\Mvc\Application::init($appConfig)->run();
You can modify this file according to your needs, but for this tutorial, we will use the default settings.
Creating the controller and the view
The controller is the class that handles the requests from the users and interacts with the model and the view. The view is the script that generates the output for the users. In Zend Framework, controllers and views are organized into modules. A module is a group of related controllers and views that provide a specific functionality. By default, the skeleton application has one module called Application, which contains a controller called IndexController and a view called index.phtml.
The IndexController class is located in module/Application/src/Controller/IndexController.php. This class extends the abstract class Zend\Mvc\Controller\AbstractActionController, which provides some common methods for controllers. The IndexController class has one method called indexAction, which is the default action for this controller. An action is a method that performs some logic and returns a response. The indexAction method looks like this:
public function indexAction() return new ViewModel();
This method simply returns a new instance of Zend\View\Model\ViewModel, which is a class that represents the data and options for a view. By default, the ViewModel will look for a view script that matches the controller name and the action name. In this case, it will look for module/Application/view/application/index/index.phtml.
The index.phtml file is located in module/Application/view/application/index/index.phtml. This file contains some HTML code that displays a welcome message and a navigation menu. The file looks like this:
