Many business owners or ordinary individuals consider building a website so as to give themselves a presence online. In the event you are considering building a site you might want to go online to visit some sites to get a few ideas first.

A website can add credibility to your business. These days many folks jump online in order to research products and services. Having a website will enable prospective clients find out more about your business. This will also help you to present your products and services in a more detailed fashion.

The key to building a successful website lies within understanding what the web is all about. The internet in its former years was called the information super highway. The reason why people use the internet is to gather information for multiple reasons.

What is needed is to understand how people search for information online. What keywords they use and how best to get your website in front of their eyes. So while they may not search for your particular product or service you may find relative terms that you can use that would be relevant.

Once you do this you then need to consider constructing your web pages so that they are both relevant to the individual searching and relevant to the search engines.

This way your web pages will get indexed and ranked for your chosen keywords sooner rather than later. This will enable your site to get free traffic and having your site found in the search engines will also add further credibility.

To conclude the main reason any business considers building a website is to enable them to reach a broader range of customers and as a result increase their business. So when building your website understand the fundamentals and build it with the customer and search engines in mind.

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.

What Is PHP?

The full form of PHP is Hypertext PreProcessor and is a server-side scripting language. The PHP code can be combined with regular HTML tags and parsed on the server. The creator of PHP, Rasmus Lerdorf first displayed the language in the form of a Perl script . In 1997 it was adapted by Andi Gutmans and Zeev Suraski to use a C-written compiler. They completely reconstructed the original PHP into the web language that we know and use today.

Uses of PHP

It is used in the creation of dynamic web pages. Web developers like it because of its fast parsing and flexibility and versatility. PHP is a popular tool for managing a form's data after it is submitted and comes built in with many different interfaces and API's. It has database capability built into the language, the most common database being MySQL. Typically the PHP can connect to any SQL enabled database.

The Syntax of PHP is similar in structure to Perl and C where curly braces { } define blocks of code and semi-colons specify the end of a statement PHP is as easy to learn as Perl. It maintains all the traditional loops, if/else, and subroutines that are expected in a programming language. One difference between the two is that the code'?' is embedded in with the HTML; you could however, use a separate file. The PHP code is different from HTML code by use of the opening and closing tags. When it finds a PHP file, it tells the server to scan through for these tags, and execute the code in between them. The server recognizes a PHP enabled file by its extension, .php. These are essentially HTML files with PHP codes in them.

Getting Started

To start PHP requires a server with PHP installed and a simple ASCII text editor such as Notepad or VI, eMacs, Kate, etc. for a UNIX/Linux machine.

What are the problems faced by PHP?

It is case sensitive. For example if you name a variable $MyVar, you cannot call it as $myvar or $mYvAr. In case you forget to close your curly brackets, then it helps to indent lines inside the curly braces so that any missing braces can be spotted easily.
