Yii is a component-based high-performance PHP framework for developing large-scale Web applications. Yii is written in strict OOP and comes with thorough class reference and comprehensive tutorials. From MVC, DAO/ActiveRecord, widgets, caching, hierarchical RBAC, Web services, to theming, I18N and L10N, Yii provides nearly every feature needed by today’s Web 2.0 application development. And all these come without incurring much overhead. As a matter of fact, Yii is one of the most efficient PHP frameworks around.
2. CodeIgniter

CodeIgniter is an Application Development Framework – a toolkit – for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.
3. CakePHP

CakePHP is a rapid development framework for PHP which uses commonly known design patterns like ActiveRecord, Association Data Mapping, Front Controller and MVC. Our primary goal is to provide a structured framework that enables PHP users at all levels to rapidly develop robust web applications, without any loss to flexibility.
4. PHPDevShell

PHPDevShell is an Open Source (GNU/LGPL) Rapid Application Development framework written using only PHP with no Javascript and comes with a complete GUI admin interface. It is aimed at developing admin based applications as plugins, where speed, security, stability and flexibility are essentials. It is designed to have a very easy learning curve without complicated new terms to learn. The need for a light, fully functional GUI with limitless configuration brought forward PHPDevShell. We strive to keep direction and focus in our development according to our moto.
5. Akelos

The Akelos PHP Framework is a web application development platform based on the MVC (Model View Controller) design pattern. Based on good practices, it allows you to:

• Write views using Ajax easily
• Control requests and responses through a controller
• Manage internationalized applications
• Communicate models and the database using simple conventions.

Your Akelos based applications can run on most shared hosting service providers since Akelos only requires that PHP be available at the server. This means that the Akelos PHP Framework is the ideal candidate for distributing standalone web applications as it does not require any non-standard PHP configuration to run.
6. Symfony

Symfony is a web application framework for PHP5 projects.

It aims to speed up the creation and maintenance of web applications, and to replace the repetitive coding tasks by power, control and pleasure.

The very small number of prerequisites make symfony easy to install on any configuration; you just need Unix or Windows with a web server and PHP 5 installed. It is compatible with almost every database system. In addition, it has a very small overhead, so the benefits of the framework don’t come at the cost of an increase of hosting costs.

Using symfony is so natural and easy for people used to PHP and the design patterns of Internet applications that the learning curve is reduced to less than a day. The clean design and code readability will keep your delays short. Developers can apply agile development principles (such as DRY, KISS or the XP philosophy) and focus on applicative logic without losing time to write endless XML configuration files.

Symfony is aimed at building robust applications in an enterprise context. This means that you have full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized. To match your enterprise’s development guidelines, symfony is bundled with additional tools helping you to test, debug and document your project.

History of PRADO

The very original inspiration of PRADO came from Apache Tapestry. During the design and implementation, I borrowed many ideas from Borland Delphi and Microsoft ASP.NET. The first version of PRADO came out in June 2004 and was written in PHP 4. Driven by the Zend PHP 5 coding contest, I rewrote PRADO in PHP 5, which proved to be a wise move, thanks to the new object model provided by PHP 5. PRADO won the grand prize in the Zend contest, earning high votes both from the public and from the judges’ panel.

In August 2004, PRADO was hosted on SourceForge as an open source project. Soon after, the project site xisc.com was announced to public. With the fantastic support of PRADO developer team and PRADO users, PRADO evolved to version 2.0 in mid 2005. In this version, Wei Zhuo contributed to PRADO with the excellent I18 and L10N support.

In May 2005, we decided to completely rewrite the PRADO framework to resolve a few fundamental issues found in version 2.0 and to catch up with some cool features available in Microsoft ASP.NET 2.0. After nearly a year’s hard work with over 50,000 lines of new code, version 3.0 was finally made available in April 2006.

Starting from version 3.0, significant efforts are allocated to ensure the quality and stability of PRADO. If we say PRADO v2.x and v1.x are proof-of-concept work, we can say PRADO 3.x has grown up to a serious project that is suitable for business application development.
8. Zend

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 like Google, Amazon, Yahoo!, Flickr, as well as API providers and cataloguers like StrikeIron and ProgrammableWeb.
Expanding on these core themes, we have implemented Zend Framework to embody extreme simplicity & productivity, the latest Web 2.0 features, simple corporate-friendly licensing, and an agile well-tested code base that your enterprise can depend upon.

9. ZooP

The Zoop Object Oriented Php Framework (The Zoop PHP Framework for short). A framework written in and for php.

The Zoop PHP Framework is stable, scalable and portable. It has been in production use for the last 5 years and has been used in many production environments. The Zoop PHP Framework is designed to be fast, efficient and clean. It is easily extendable and you choose to include only the functionality you use.

With Zoop an inexperienced coder can make secure web applications quickly. A more experienced coder will really appreciate how flexible The Zoop PHP Framework is. Both experienced and inexperienced coders alike will appreciate the automations that are at his/her disposal to handle mundane tasks.

The Zoop PHP Framework encourages separation of display, logic and data layers(MVC).

The Zoop PHP Framework is made up of many components and integrates many different projects including smarty (http://smarty.php.net) and the prototype AJAX framework. It also makes use of PEAR modules (http://pear.php.net). The efficient core components handle many of the functions you would have to code yourselves. Zoop’s integrated error handling can be configured to log errors for production environments, and is highly informative and readable which makes bugs easy to find and squash.

Zoop has been designed to make the developers life easier by providing tools to make efficient use of his/her time. On of our more unique and notable features is our implementation of GuiControls, a revolutionary idea in PHP that provides many form widgets with validation completely integrated, as well as a framework to develop your own guiControls extremely easily.
10. QPHP

QPHP stands for Quick PHP and is a MVC framework similar as architecture to ASP.NET.

I, as the author of the project, have spent the last 8 years working on web projects using various Java frameworks, ASP.NET and PHP. This framework tries to get the best of the above platforms as well as to avoid the problematic parts. Basically it:

• Brings the elegance of Java and C#
• Drops all Perl like bizzare statements that other PHP frameworks use
• Relies extensively on OOP concepts

Smart Image Resizer

sIFR (Scalable Inman Flash Replacement) was one of the first dynamic text replacement methods, developed in the spring of 2005. It uses JavaScript and Flash to convert any text you designate on a page to any typeface you choose and has been released as open source under the CC-GNU LGPL license, so it’s free for anyone to use.

sIFR is fully accessible to screen readers, because it simply displays the original text if JavaScript or Flash isn’t enabled. And because of the way text is rendered, if your visitors zoom in using a browser’s text-zoom option, the replaced text will also zoom in (only when the page loads, though, not if they zoom in afterward).

2. Cufón

Cufón was created as an sIFR alternative. It uses JavaScript to replace text, without Flash, making it more widely compatible than sIFR.

3. Typeface.js

Typeface.js is a JavaScript-based dynamic text replacement method that embeds fonts on your page rather than converting them to images. This means that visitors are presented with a page that acts (and really is) like a regular HTML and CSS page.

4. PHP Image Replacement

PHP Image Replacement (also known as PIR) is based at least in part on the method originally outlined by A List Apart but modified to be used with jQuery for better control over the end images produced.

You probably use the FeedBurner badge to show the count of your feed subscribers and Twitter badge to display the number of your followers on Twitter. Now there’s a new badge in town to display visitor data from Google Analytics onto your WordPress powered website.

Called Google Analyticar, this plug-in uses the Google Analytics API to prepare a stats widget that will show statistics (unique visitors and page views) about yesterday’s visitors on your site.

Sitemeter and Statcounter too offer similar ‘visitor counter’ badges but since all of us have Google Analytics by default, the Analytics badge may come more handy.

The same Google Analytics plugin also includes tracking of external links as well as clicks on downloadable files like PDF, MP3, etc
