Most web development projects include one or more of the following elements...

• Database design and creation
• Server-side computer programming
• Client-side computer programming
• Web page design

Each of these elements has to work in its own right, and in cooperation with the other elements. The more complex the project, the harder it is to bring it all together and make it work correctly.

How to keep the cost down

Here's how you can make sure your web development costs don't run over budget...

1. Insist every aspect of the development is described in an Agreement document, and make sure both you and the developer sign it
2. Don't make changes after work has started

The key to achieving the second of these two items lies with the first. You should insist that an Agreement document be created, and sit in on the process.

You need both end-users and developers in the same room, working through each aspect of the development. The end result must be a document that fully describes the development, is clear (unambiguous), and easily understood by both users and programmers.

Every minute you invest creating this document greatly increases your chance of bringing the project in on budget.

Why it's worth it

Many of the problems that usually cause headaches during a complex development could have been discovered in advance, if an Agreement document had been created. When users and programmers get together and discuss their respective needs thoroughly, the resulting development is far more likely to go smoothly.

This kind of interaction forces both users and programmers to think through what's actually required to make the system work. The ongoing interaction reduces the risk that person A assumes person B knows what they're talking about.

Users are committing to a specific set of functions for an agreed price. The developer is committing to develop those functions for an agreed price. This means both users and developers have a self-interest in being thorough.

Should a user change his/her mind about something after the Agreement document is signed, the cost of development must be renegotiated. This punishes the user for failing to think things through.

Should the developer discover he/she hasn't fully understood what's required to complete some aspect of the project, he/she can't ask for more money. This punishes the developer for failing to break down each stage of the development and understand what's involved in completing it.

Assuming you do your part, you won't need to make changes after the work has started. As a result, you'll bring the project in on budget even if the developer hasn't done his/her job properly.

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.

The concept of web development may include more than a singular ecommerce website.

I have talked about the subject of web development in light of positively constructing a website. I've also talked about the mentality needed to envision the entire site prior to launch so you have some idea of where you want to go. The goal also included the need for a plan for growth and site expansion.

This article looks at the subject from the point of view of a corporate office with a few satellite offices that support and expand the potential of the primary business.

In a brick and mortar store environment it is often true that a business will start in a singular location. As trust is built through longevity and commitment to quality and service the business grows. If the business does well the owner may decide to develop a second store in another city within the region of primary service and support. Other stores may be opened as a result of the ongoing success of the overall operation. The idea is multiple stores - one brand.

Web development may be the mirror image of the brick and mortar model. Why do I say mirror? Well, because in the case of an online environment an ecommerce business owner may be better served by starting with the secondary stores and building up to the primary online business portal.

If you're thinking, "That does seem backwards," allow me to explain.

These satellite stores should have direct links to your primary site. Each satellite may have its own emphasis, but will always relate to the thrust of your main business. The end goal remains the same, multiple stores - one brand.

Why develop more than one site?

In web development the idea of more than one site could mean improved site rankings for your primary site and additional opportunities to reach potential customers.

Think of it this way. Each satellite website you develop can take on a distinct list of keywords or phrases. Each will be associated with your primary product. All content on the site will be geared toward the specific keyword or phrase.

If you have four supporting sites that can go online at the same time as your primary site you have five distinct opportunities to reach consumers with your message. Work to optimize each site for search engines and select unique and researched keywords or phrases for each site.

Is that the only benefit?

By developing your web presence this way you begin the process with backlinks already in place from the satellite sites to your primary web presence. As your Search Engine Optimization (SEO) strategies begin yielding results they should do so in all five instances and ultimately this effort benefits your bottom line.

By having five separate sites that market the same product from a slightly different vantage point the potential improves for increased sales. This is true not just because there are more sites for consumers to view, but because search engines will connect with this scenario and provide improved rankings earlier.

Proper web development may include more than one site and more than one approach as the vehicle used to maximize the overall potential of the product or service being marketed.
