Symfony & Zend Framework
Symfony first of all is a PHP framework.
Basically, a framework consists of:
A toolbox - a set of prefabricated, rapidly integratable software components. This means that you will have to write less code, with less risk of error. This also means greater productivity and the ability to devote more time to doing those things which provide greater added value, such as managing guiding principles, side effects, etc.
Best Practices guaranteed! A methodology – an “assembly diagram” for applications. A structured approach may seem constraining at first. But in reality it allows developers to work both efficiently and effectively on the most complex aspects of a task, and the use of Best Practices guarantees the stability, maintainability and upgradeability of the applications you develop.
And although it might be obvious, we thought it best to say it anyway – Symfony is a PHP framework, which means that it permits web applications to be built in PHP!
Next to being a PHP framework, Symfony is a philosophy
What could be more useful than an application developed by users for their own needs? This is the story of the genesis of Symfony – born from the imagination of the web designers at SensioLabs, a web developer in its own right. Symfony was made available to everyone under an Open Source license. This benefits other developers, who also have the ability to improve it by adding their own modules. All this was done in an environment of Best Practices, standardization and interoperability of applications.
And behind Symfony, there are people. Sensiolabs created Symfony to solve their own web development problems and they’re pleased to promote it. Behind Symfony there is also a community of developers, users, and contributors which has formed around Symfony over the past 5 years.
Extending the art & spirit of PHP, Zend Framework is based on simplicity, object-oriented best practices, corporate friendly licensing, and a rigorously tested agile codebase. Zend Framework is focused on building more secure, reliable, and modern Web 2.0 applications & web services, and consuming widely available APIs from leading vendors.
Zend Framework features include:
- All components are fully object-oriented PHP 5 and are E_STRICT compliant
- Use-at-will architecture with loosely coupled components and minimal interdependencies
- Extensible MVC implementation supporting layouts and PHP-based templates by default
- Support for multiple database systems and vendors, including MariaDB, MySQL, Oracle, IBM DB2, Microsoft SQL Server, PostgreSQL, SQLite, and Informix Dynamic Server
- Email composition and delivery, retrieval via mbox, Maildir, POP3 and IMAP4
- Flexible caching sub-system with support for many types of backends, such as memory or a file system.
- Frameworks and best practices mean reduced training costs and quicker time-to-market – important factors in adoption decisions. Built so you can pick and choose just the pieces you need to turbocharge your web applications – all your developers know where to find their PHP / Zend Framework code, speeding new development and reducing maintenance costs.
