This post give you a insight view of various PHP frameworks.....when should you use it ...which is suitable for you etc.

Many OO languages have the concept of a single base class from which all other classes are explicitly or implicitly descended. For example, Ruby, Java and .NET all have Object. It’s a very common belief that PHP implements stdClass as a base class for all objects, but this is in fact not the case

A lot of things have changed since PHP 2.0 most of them for the better. But many of its faults will not be changed or cannot be changed.

Today, we released Zend Framework 1.7.0. This release features AMF support, JQuery support, and Twitter support, among numerous other offerings. For this particular release, we tried very hard to leverage the community. The majority of new features present in 1.7.0 are from community proposals, or were primarily driven by community contributors. For me, this represents a milestone: ZF is now at a stage where fewer and fewer core components are necessary, and the community is able to build off it and add extra value to the project.

Intruders can make nasty damages to your web services just by using Replay Attacks. So you have to design your services carefully to detect and avoid them. This post discuss the possible solutions on detecting replay attacks with PHP web services.

Below are a list of my top five quick-and-dirty strategies for improving database performance in web applications. These suggestions are culled from recent experience and mixed with some ideas that I've implemented in my own code. They're not high level, but they are something we need consistent reminders about. Here they are...

As test writers, when we see code with poor test coverage the most natural approach is to think that we ought to write more test cases, indeed we have been doing exactly that for PHP. The number of test cases for the PHP implementation has increased from roughly 3000 to 5000 over the past two years.

A few years ago a friend of mine tried to convince me to learn ASP.NET because it was much better for my career than PHP. Not because ASP.NET is better than PHP but because .NET web development is a profession while PHP is only a skill.

This article covers PHP implementation of a couple of Yahoo's website performance recommendations for faster web page loading.

Users don’t like caching! They want to see the changes immediately. Otherwise they get confused and write you bug tickets or flame mails. But if you do not use caching the user comes and make your CPU’s burning. If your site is down you not only get mails from your users, but also from your management.

For the upcoming PHPUnit 3.4 I have implemented support for the idea expressed in the paper mentioned above.

The e-book version of the Pragmatic Programmers release Rails for PHP Developers written by Derek DeVries and Mike Naberezny occupies now some of my scarce hard drive space for several months, and today I managed to hit the last page of it. In case you're interested in knowing if it's worthy to sacrifice some rare hard drive or bookshelf space for this book read on.

Documentation. The word illicits a mix of fear and depression in even the most hardened programmer. For many it's a hard slog through endless boredom which occurs throughout, or at the end of, the development process. Documentation is never the easiest task. Good documentation takes time, patience, lots of questions about the subject matter (no matter how familiar you think you are with the subject matter, you can be assured you have some misunderstandings), and a degree of ability in condensing knowledge to a form people can instantly connect with.

The PHPClasses.org site is encouraging the production and sharing of slide presentations about PHP components, so PHP users may benefit of better learning materials.

PHP V5.3 is designed to prepare developers for PHP V6 when it comes by adding new features, cleaning up existing features by tweaking the functionality, fixing platform-specific issues, and deprecating old features that won't be in future versions of PHP. In this "What's new in PHP V5.3" series, discover the new features and see how they can be used in your Web application.

Many a web application can be enhanced with a decent graph to show data. Unfortunately out of the programming languages / frameworks that we have available to us, none seem to be very forthcoming with decent graph components, and it is left up to third party solutions to provide the necessary.

PHP V5.3 is set to be released by the end of 2008, and many of the new features in this release have been in the planning stages for a few years. In this "What's new in PHP V5.3" series, we'll look at these new V5.3 features, and see how they are used and how they can be used in your Web application.

Yii is a high-performance component-based PHP framework. It comes with a rich set of features. From MVC, DAO/ActiveRecord, to theming, internationalization and localization, Yii provides nearly every feature needed by today's Web 2.0 application development.

Using CI's ability to create my own custom libraries, I was able to create my own custom 'Model' which extends from the core 'Model' object. How this simple architecture has cleaned up my code is simply remarkable.

FireSpider is a an extension for Firebug that can help you find broken or misleading urls and optimize your web page for search engines.

So I’ve had quite a bit of experience with authorize.NET and PHP and I’ve found it’s difficult to find resources that provide textual examples for integrating the payment processor. I’ve put together a generic tutorial from documentation that is public. Of course, you will have to specify your Transaction ID and API Login ID. So here you are. If you need assistance or have any questions, feel free to leave a comment.

A late followup to Rasmus' talk, Simple is Hard, demonstrating that it's not that hard after all. Demonstrate simplicity compared to other frameworks not only with an "Hello World" but with queries. Conclude by giving optimization guidelines.

My personal site has been through a number of transitions. It was initially a flat/traditional/simple PHP based site with a custom ORM layer. Then I decided that I spent longer maintaining the site and wanted to blog more so I changed to using Serendipity. After a while of still not writing many posts and not updating Serendipity for a while my site got hacked. I'd always advised my clients of the risks of using open source software - that you have to keep it updated otherwise a security vulnerability found in the software means you are one evil mind and a google search away from being hacked - and then ignored that advice myself.
