Most websites that are created these days, are making use of the latest web applications in their site, so as to make their website appear more technically sound and upgraded too. Maintaining a standard website helps in creating a better impression upon the people than otherwise.

There are several web applications available and several that are in the pipeline. If you plan to develop your own web application and wish to be known someday for its introduction, there are a few things that you need to keep in mind before actually wishing to launch them.

The first thing that you need to analyze is the scope of the web application that is planning to develop. The scope of the application should be well researched and developed considering the users of the application and its advantages to them.

A web application usually has a number of competitive web applications as well. It is essential to do an analysis of the competitor web applications as well. You need to review the competitor website and the web application development he has undertaken. Make use of the successful technology that they have used, which can be bettered by adding to it other functional techniques.

Every website that you make with web application development must have certain practical solutions ready that will make building your website an easier task than what it considers.

A good web application generally takes a long time to be constructed and to become fully functional. It is therefore not advised to rush through any of the web application while it is being constructed. Give the developers the required time they need in order create a completely functional web application.

Once the application is ready to be installed in the website, it is important to do a quality check of the website a few days before they can actually be installed in the sites. This is an essential step since; even a small mistake can make the website drop from a height to no where and crush.

Functions are used to perform a well defined task that is normally repeated at various places within a web site, web application, or other software application. The function sometimes needs certain information before performing its task, and sometimes returns a value to the calling page or program.

An example of how to use a simple function in PHP:

 function showMessage() {
echo "{$_SESSION["message"]}"; }

The above example shows a very simple function that displays the contents of a session variable called 'message'. The idea being that while a user is using a web site, etc, various messages are generated and stored in the 'message' session variable. Whenever the showMessage function is called, the contents of the session variable are displayed. So, for example, when the user logs on, you could display a message saying that they have done so. Likewise, when they log off, a different message could be displayed.

Calling a function

To call the showMessage function, you would just need to include the line:

showMessage()

in the web page (wrapped in php tags to distinguish it from normall HTML).

Passing values to a function

Often, a function requires one or more input values in order to perform its task. For example, take the following example that takes two numbers as input, and adds them together. The result is then returned to the calling web page or program.

function addNumbers($number1,$number2) {
$answer = $number1 + $number2;
return $answer; }

In the calling program we would have something similar to the following:

$number1 = "5";
$number2 = "6";
$sumOfNumbers = addNumbers($number1,$number2);
echo "$sumOfNumbers";

Obviously, in a real program you would not have the numbers hardcoded like this, but they would be obtained from user input or by some other means. Notice also that although the name of the returned variable is $answer, the calling program makes no reference to that. We could, if we wanted to, change the calling program to:

$answer = addNumbers($number1,$number2);
echo "$answer";

which might make things slightly easier to understand.

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.
