Reusing pieces of HTML code is a common way of making web sites (or web applications) more consistent, reliable, and more manageable. Even a small web site consisting of perhaps 20 or 30 web pages can benefit from reusing code for header and footer sections, for example. If the same header or footer is used across all the pages on the site, it makes sense to put the header and footer code in separate files, and then call those files to insert their contents where required.

PHP offers two statements that can be used for inserted the contents of one file inside another: include() and require(). These two statements are virtually identical, with the only real difference being that if require() fails, it gives a fatal error, whereas if include() fails it just gives a warning. For this reason I tend to use the include() statement as it just seems slightly more friendly.

So, to include the contents of a file called header.inc inside a web page called index.php, you would just need to insert the following line of code (wrapped in PHP opening and closing tags) inside index.php.

Include 'header.inc';

As PHP takes no notice of the extension used for the included file, you can use whatever extension you want to. Be careful though, if you put passwords inside an include file with a .inc extension, they will be visible. You can get around this by putting include files that contain sensitive information outside the document tree to prevent people from browsing to them.

In Part 2 we'll look at the use of functions when developing web sites and applications.

I think the biggest mistake many of us make when we set out to build a website to make money is not to think out clearly how we are going to achieve this under our given set of circumstances.

We immediately jump on whatever bad wagon promises the best opportunity and hope to be able to achieve the same results. While hope is always nice it is action that will bring results. This is why it is imperative at the outset for you to figure out what you are prepared to do and how you are going to go about doing it.

For example list your strengths and what you are comfortable doing. Then you are going to look for ways and opportunities that will compliment your strengths.

If I had done this years ago I would have been a lot more successful. What I did instead was jump on the latest greatest opportunity, then when I would get the material I would be disappointed because many of the techniques listed where not in my field of expertise.

For example it would involve me having to cold call people to make sales and this is something I hate to do. So your first objective when setting out to build a website is to build it around a subject that you have some relationship with. Basically something that interests you.

Start out broad and be prepared to be taken down different paths that may yield more positive results in other words do not be too ridged.

Research is critical the more time spent researching the better your chances of success. Visit forums relative to your topics of choice and see what people are looking for - then with this information start to structure your site.

There are many site builders out there that can help. The one I used took care of the hosting and also helped me to market the site. This was very helpful especially starting out.

To conclude figure out what you want to do then be prepared to be adaptable based upon what the market demands. Then build a site that addresses their needs and provides solutions and you will make money.

What do you think is the most important aspect of a website? Let me put the question the other way around. When you go online and visit websites what do you look for? The first thing you want is information. This helps us to make decisions.

Before you buy a car for example you want to know what the safety ratings are and how many miles per gallon it gets. Then you may want to compare it to other cars in that category. All this information is provided through content.

Good content on a site helps you to make decisions and when you experience this you feel you are getting results. As a consequence of this credibility develops and you will use this website as a reference guide which means you may visit it again.

This makes sense right? It's funny because often the secrets to success lie right in front of our eyes. Many times we tend to look elsewhere rather than our own actions for answers. Good content will not only benefit your site visitors but it will also help you climb the ranks in the search engines.

So when you create a website you want to build it in a way that it can provide good content. Good content is brought about by good research. Research is key as this will help you to put a solid foundation in place.

Good content will provide good advertising opportunities and your recommendations will have credibility which will lead to sales - either of your own product or somebody else's.

While all this may seem a little over your head at this point it will all become clear as you work your way through it. Start with a subject you like and start researching niches relative to it. Then you will be focused and in a far better position to build a money making website.
