Different programming languages excel at different things. I employ a number of different programming languages, and make my choice based on the task at hand. My presentations tend to be powered by Perl. My weblog is powered by Python. But my private applications tend to be written in PHP.
The developerWorks PHP Resources site will cover PHP from a perspective that may be new to some PHP users, covering such topics as Access an enterprise application from a PHP script
The developerWorks PHP Blog, however, will often touch on topics that may be new to enterprise (typically Java) programmers.
My first post on this site will cover an application I wrote in about an hour to cover a specific need. It breaks a number of "rules" that guide the development of scalable enterprise applications - in particular it does not separate presentation from content. Consequently, this application does not contain any reusable components that will ultimately find their way into a Customer Relationship Management system. I'm entirely OK with that.
Still, the application is centrally managed, requires zero deployment, is accessible everywhere and portable across a wide range of client operating systems and browsers. All good traits to have.
The application is a vocabulary test. My daughter weekly gets a list of words and their definitions to study. At the end of the week, there is a test where she needs to match the words with the definitions. At first, I helped her study using flash cards, but this seemed like an obvious candidate for automation.
The UI for this application was obvious... I precisely mimicked the layout of the test.
Nothing in this application couldn't have been done with JSP. However, to do so would have required additional effort, effort that does not result in a more functional end result.
And it wouldn't have been as much fun.
Not everybody may have the diverse set of skills required to pull together such an application in one sitting. However, a quite larger set of people can copy such an application and successfully make meaningful changes to it.
In my experience, that's how people tend to learn languages such as PHP. Some refer to this as Progressive Disclosure.
