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.

This is a question you will have to address. Many folks just a build a website but do not think out why they are really doing it. As a result they don't take it seriously and therefore they do not get serious results. This makes logical sense right?

A website in and of itself means nothing unless it has visitors and achieves a certain objective. So you have to be clear what you want to achieve as this will help you focus on your research and build a site that can achieve your objective. Quality research will help you build a quality website.

To build a business online you are going to have to build a relationship with your site visitors. You will need to show them how to connect the dots and you can only do this by providing valuable content that is benefit driven.

Furthermore you are going to have to show them solid evidence of how your product or service can help them achieve results. Connecting the dots means moving them closer to their outcome. Once they can follow this and see how it will work for them you will naturally build credibility which will result in you having a profitable website.

As mentioned when you build your site you want to clearly have your visitor's objectives in mind so that you can address their concerns and overcome their objections. If you can help them achieve their goals it will be a win win situation for all parties concerned.
