In the first generation web technologies were developed to tap the resources from a commercial point of view. The patrons perceived the development of the new media to bring more profits in terms of monetary gains. But as the web world advances to take over new responsibilities and roles, its very character is observing changes that are more or less inclined towards the human side.

The maxim of Web 2.2 which goes as 'Web for the people and by the people' clearly gives an insight of the new character adopted by the web and the emergence of community services. In the new era the developmental work as such emphasizes on increased participation of the audience member. It is this audience, the users spread all over the world that drive the web today.

In order to bring increased levels of participation and give way to more interactions, many community service programs have been thrown open to the people. At present a plethora of community services like Face book, Orkut, Hi5, etc., connect the people and communities at large. Blogs and forums have further helped as better tools and platforms for interacting with each other. Then there are Wikis that make available important online resources for the people at large.

In community web development technologies have primarily been redeveloped to make them user-friendly and interactive. On technical front both the designing as well as the scientific coding have been utilized to forge the end product for the benefit of the people at large. As of now many of these products or online services are available as free and open ended services.

Hence community web development incorporates all those elementary changes that are required to disentangle the web from commercial values. The services and products under it have primarily been designed and developed to allow the people to come nearer and enjoy the benefits of new technology. It is worth mentioning at this point that many business organisations develop such products or deliver services to have better relations with the public. Occasionally it might happen that a free community service in the due course of time change its preferences and take a commercial identity.

Website Accessibility means the website accessible to all the users in the web including visitors with disability. Many website owners know that their website is available in the internet for visitors to access information but possibly may not know whether their website is easily accessible and even be unaware about Disability Discrimination Act (DDA).

According to Disability Discrimination Act (DDA), all the business should make their services accessible to disabled users. There is also a section in DDA which addresses that if a business offers an online service, even the information is on a single page, then the business is responsible for making an effort to make this information accessible to disabled users.

All new websites that are designed and developed should now follow the W3C (World Wide Web Consortium) and Web Content Accessibility Guidelines (WCAG) against which the accessibility of the website is measured. But when the website is found isn't complaint, then anybody can sue you legally, if they want to.

By following these guidelines, you enhance the professional look of your website, provide access to visitors who previously had not no choice, thus increasing your business prospects and finally not to forget, your business is legal.

Some basic Guidelines to increase the accessibility of the visitors

Validate HTML and CSS: To check if the HTML and CSS used is valid, W3C validator can be used. It is necessary that websites are checked as the validator automatically tells you about any errors and accessibility issues in the web pages.

Image and alternative text: For browsers which don't support images, alternative text can be used to explain what the image is about as the user will only see the text.

Resize font text: Most of the internet browsers use Internet explorer to search for information. If the size of the text can be increased by choosing the font size to the largest then it means that your website is accessible to visitors.

Use of Java script: Websites are not easily accessible when java script is disabled. Mostly people have the java script support switched off, if that's the case then make sure that you use the Java script sensibly and unnoticeably.

Check for the following,

1. Website is accessible without the use of a mouse

2. Website has a Sitemap

3. Website has link text relevant to the content (blind users use tabbing while browsing websites from one link to the other)

What is PHP?

PHP stands for PHP: HyperText Preprocessor, it is a server-side scripting language, and as the name goes, it is to create dynamic and interactive Websites for your visitors. Maybe you currently make your Websites in HTML? HTML alone cannot create dynamic Web pages, HTML is clearly defined as a static language, as it is always static and mainly is used for structuring (or styling, in some cases) a document (or a Web page, if you like).

What do we mean by server-side scripting?

You may already know, but HTML is a client-side language, so the browser translates the HTML code into "bytecode" that the computer can understand, and so the computer translates bytecode into what we can clearly understand, text, for example. Server-side scripting is a little different, a little bit more added to the story. As with PHP, server-side scripting languages have an interpreter inside a machine, that translates the code (in our case, PHP code) to HTML code (that the browser can understand), and then the same process will take place with the browser translating the HTML code to bytecode, and so forth. With server-side scripting languages, you don't need anything adding to your browser or computer, as the interpreter inside the machine that hosts the particular Website does most of the work.

What's the fuss with server-side scripting languages, then?

The thing that makes server-side scripting a must nowadays is because it can generate dynamic Web pages, but what do we mean by dynamic Web pages? Well, imagine you wanted to start a forum, and you used HTML. Okay, you used a form to submit the data and it is sent to your e-mail address, and you have to edit the static Web page every time you want a new post added. That, to me, would be the most annoying job of creating a Website. However, with PHP (or any other server-side scripting language, for that matter), can be completely automated, and you'd not have to edit your file even once! The thing that PHP does, is sends the form data to a different page, saves it in "pre-defined" variables (things that store a value), and using something called a "while loop" that continually loops all the posts saved in the Web page - and that's it! PHP stores the posts in a MySQL database (something that holds data, if you like, like member accounts, etc) and uses that as long-term memory.

But if we're talking about server-side scripting languages, what makes PHP different from the rest? Well, simply put, PHP is probably the best thing that has come into the server-side scripting genre. If you have heard about other scripting languages like Perl or ASP/ASP.NET, you'll come to find that they are extremely hard to learn from. Put it this way, the majority of Web developers that use ASP.NET, for example, are those who have come from a different programming background, like have known VBScript, or other languages that's in relation to ASP.NET, the same with Perl. The difference between PHP and the rest, is PHP is incredibly easy to learn, especially for the newbies towards this industry, and PHP has took several steps to ensure an easy introduction to those newbies to the world of programming. Let's do an example, lets see which is the easiest to understand, out of PHP, VBScript and Perl, by doing a simple "Hello World" program, that outputs text to a Web page:

PHP:

echo "This is some text that'll be shown in a Web page...";

VBScript/ASP.NET:

Response.Write("This is some text that'll be shown in a Web page...");

Perl:

#!/usr/bin/perl

print "content-type: text/html nn";

print "This is some text that'll be shown in a Web page...";

Okay, now I am not going to say things like "well, obviously PHP is the easiest to understand" - as obviously, we all have different preferences, but what I can say is, that they all do the same thing. Which seems the most logical to you? In my opinion, the two most logical ones for me is PHP and VBScript/(ASP.NET).

Now it's up to you which one you want to go ahead with, experiment which one is best for you, after all, we all have dfferent tastes.

Good luck!
