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.

Nowadays a quality website is proven to be a key tool for spreading information about a company, its services and products to a vast audience across the Globe. But what is a quality website? It seems, there is no a simple answer to the question. Still there exist some general factors that determine the quality of a website and therefore its success.

An appealing design, comfortable navigation and quick website loading definitely attract visitors. The more difficult task is to convert visitors to clients and keep them coming back. This can be done by providing high quality content and updating the website on a regular basis. However for a website owner it can become a serious problem, as website maintenance requires technical skills and programming knowledge.

Of course, there are a lot of companies providing a variety of web mastering services such as news or upcoming events additions, product list changes and additions, photos, graphics and text additions and updates, and more. It all seems to be ideal but for one thing: as a rule, their prices are very high and not always affordable for small businesses.

Another solution to the problem of website maintenance is the implementation of a Content Management System, also known as CMS. It is an application combining web-based tools, web templates and a database in order to manage a content of a website. Content Management Systems are perfect for websites that require constant updates and additions.

CMS usually have user-friendly interface giving freedom for text editing, as well as for image managing. In fact, one of the main advantages of these systems is that you will be able to manage a web site's content without having to study web programming and deal with time-consuming technical tasks. All necessary website modifications and updates will be done immediately, no matter where you are: at your workplace, at home, or on vacations. You will just need a computer connected to the Internet.

There are a lot of different CMS packages available, some of them are free or open source, and some are commercial. A commercial Content Management System has a number of advantages, not the least of which is a guarantee of professional tech support and the possibility of development of specific extensions personally for your website. Commercial software is usually associated with a relatively high degree of safety as opposed to open source. So, if a website owner has the resources to purchase such a system, then it can be the safest way.

CMS also vary by structure and features. For example, Content Management Systems that use module architecture can be tailored to suite the needs of almost any website, be it a business site, an online shop, or a multilingual portal. These CMS offer additional modules and extensions covering up assorted functions. It may be a good choice for those website owners who are planning to expand their business and widen the range of their web services in future.

On the whole, the implementation of a CMS is a perfect solution for a wide variety of websites. Content Management Systems make it much easier for non-technical users to add, edit, and update their content on websites. It also helps to save a good sum of money as website owners do not have to pay a web master for their website maintenance.

If you have ever been to a "bad" website, you didn't need an expert to tell you it was a bust. Maybe you didn't know exactly why it was bad, but dysfunctional web sites tend to exhibit similarities that make them unlikely success stories.

For instance, have you ever visited a site and wondered "what are they selling anyway?" I know I have. I get frustrated with websites like these and quickly start my search again for a website that focuses on the information I was looking for.

A well designed website can either make or break your website success. The tips below will help you get started and to learn what works for a successful website. These tips are by no means all-inclusive; you will also learn a lot through "trial and error" just as with any brick and mortar business. These tips will however, help you to avoid web blunders that hinder even more seasoned web developers and designers.

Must-Have Tip #1 - Make it clear what you do. Find a niche market and don't try to be a "jack of all trades" selling multiple and unrelated products, services, or information. Instead, figure out who your target market will be, and what products and/or services you provide that will appeal to this market. Then, stay on topic; don't throw in a bunch of irrelevant information just to try and lure visitors. They will resent the deception and you'll lose customers.

Note: It is very important to note that search engine crawlers index and categorize your website based on the text and content you provide on each page. The content on each page is also compared to all other pages on your site, so having a cohesive set of pages that focus on your niche product or service is always better than trying to provide too many products or services.

Must-Have Tip #2 - Do your visitors know how to contact you? You would be surprised how many websites leave no way for a customer to contact them with questions or to order their products and services. Think about it this way: if you stopped into a store that provided widgets, and no one was around to help you or answer questions, how comfortable would you feel spending money with that company? You wouldn't, of course, because if they can't even make themselves available for questions before the sale, they certainly won't take time for you after the sale.

If you worry about getting too much spam, or receiving unwanted phone calls by leaving your contact information on your site, make sure to add your business phone to the federal "Do Not Call" list, and use a contact form instead of just providing your email address. This won't eliminate the problem of spam (what does?) but it will make it more difficult to abuse your contact information.

Note: Always respond to email in a timely manner. Treat them as you would any business phone call. Customers typically expect a higher-than-average response rate when shopping or doing business on the internet; if it takes you longer than 24 hours to respond to an email you will probably lose a customer. Even an "I received your email and will respond to your question shortly" is better than waiting too long to get back to a customer.

Must-Have Tip #3 - Don't use flash introductory pages. Everyone knows they are fun and entertaining, but if your site is designed for sales, a business, or for a professional purpose, what will they add to your site? In fact, for many, these are just another added aggravation they have to wade through to get to the information they really want.

Note: If you must use a flash intro, be sure there is a "Skip" feature clearly marked so visitors can bypass it if they choose.

Must-Have Tip #4 - Focus your web copy on satisfying the needs of your customer. Content can make or break the sale, or determine whether a visitor stays or finds another site to shop. Be sure to provide your costumers with unique and interesting words to help pique their interest and differentiate your products and services from your competitor's.

A well-thought through home page and a few articles that prompt a desired action, while simultaneously provide information to help your visitors quickly (in one or two clicks max) find and pay for products and services will keep them interested, and coming back again and again for future information and purchases.

Note: Consider hiring a contact writer if you're at a loss with web content. This may be a significant investment, but the results, and the success of your site, will definitely be worth it in the long run!

Must-Have Tip #5 - Update, update, update. This cannot be stressed enough; if you provide no reason for visitors to show up on your site again, why would they? If the information is the same week after week, month after month, who would want to? Even your local Wal-Mart will provides weekly sales flyers to entice shoppers back to their store! Keep your site fresh and updated!

In closing, I am sure you are reading this article because you want a professional website. If you have programming skills and can write your own code, great! If not, there are many affordable, quality online website builders available; many hosting packages also provide web software and templates. With a little elbow grease and effort, you can build and maintain a successful website as well!
