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.

The greatest breakthrough of the Web 2.0 age is the advances made in web page coding. Previously, an interactive web page would require you to click on the control to trigger the action, then the request would be sent to the web pages server, and you were stuck waiting for the page to reload. This is an inconvenience on your part, as you are stuck waiting. Similarly, if you are the owner of the webpage, it is an inconvenience to your users to have to wait. Furthermore, if you are offering your services or products, you are losing potential customers and gaining downtime on your webpage.

But AJAX, which stands for Asynchronous JavaScript and XML, is a new type of web coding technology which allows you to create an interactive website that does not need to reload and communicate with the server every time an action is taken. For you as a web page owner, this means faster loading times for your customers, as well as more interaction with the page on the end users' side.

AJAX uses a combination of Java, XML, HTML, and CSS coding, all rolled into one to create a unique and interactive web pages.

Are you wondering where AJAX has been employed on the Web? Ever used Google Maps? Google Maps allows you to drag the map, zoom in and out, as well as set markers on the map without the need to bee constantly interacting with Google's server.

If you want to create a unique and interactive webpage with less loading time, allowing your members to view more in less time, AJAX coding is the way to go.

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.
