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.

So you're considering building a website and you may be feeling a little overwhelmed by it all. While this can easily happen it is wise to whip out some note paper and write down exactly what you want to achieve and what steps you need to take in order to get there.

So the first thing you are going to need to do is put the foundation in place. This will require extensive research. Now contrary to popular opinion I start this process a little bit differently than what is generally advised.

Now while we all know that you need to find a hungry market doing this can be a little more difficult than explained in actual fact that is just like everything else when it comes to doing anything online.

Actuality can be quite different from theory. So what I do is visit the article directories. I punch in a keyword that I am interested in and see what articles come up relative to that. Then I check the articles out to see how many page views they have received over a given period of time.

If an article receives a lot of page views then I know that there are a number of people looking for information relative to this subject. I also know that if I write an article on this topic that it will receive a lot of page views and as a result get a lot of click throughs to my site which will help me get traffic quickly without having to worry about what Google and everyone else does.

Next I visit the forums to see what solutions are being discussed then I go back to the articles and check what the writers are promoting and see if it is a valid good product to help people achieve the goals they desire. If so then I make note of it. Now I feel a little more confident about building a site around this theme.

The next thing you have to consider is the domain. A keyword in the domain is helpful but not essential. Your next quest is hosting. You need a good host as this is your life line.

Finally you want to be able to build the site effectively so as to achieve good search engine rankings. Keyword research relative to your overall theme will help you to do this plus you need to structure the pages properly so that you site can be understood by the search engines.

Do not worry if you lack technical knowledge as there are site builders out there to help you overcome this challenge.
