Functions are used to perform a well defined task that is normally repeated at various places within a web site, web application, or other software application. The function sometimes needs certain information before performing its task, and sometimes returns a value to the calling page or program.

An example of how to use a simple function in PHP:

 function showMessage() {
echo "{$_SESSION["message"]}"; }

The above example shows a very simple function that displays the contents of a session variable called 'message'. The idea being that while a user is using a web site, etc, various messages are generated and stored in the 'message' session variable. Whenever the showMessage function is called, the contents of the session variable are displayed. So, for example, when the user logs on, you could display a message saying that they have done so. Likewise, when they log off, a different message could be displayed.

Calling a function

To call the showMessage function, you would just need to include the line:

showMessage()

in the web page (wrapped in php tags to distinguish it from normall HTML).

Passing values to a function

Often, a function requires one or more input values in order to perform its task. For example, take the following example that takes two numbers as input, and adds them together. The result is then returned to the calling web page or program.

function addNumbers($number1,$number2) {
$answer = $number1 + $number2;
return $answer; }

In the calling program we would have something similar to the following:

$number1 = "5";
$number2 = "6";
$sumOfNumbers = addNumbers($number1,$number2);
echo "$sumOfNumbers";

Obviously, in a real program you would not have the numbers hardcoded like this, but they would be obtained from user input or by some other means. Notice also that although the name of the returned variable is $answer, the calling program makes no reference to that. We could, if we wanted to, change the calling program to:

$answer = addNumbers($number1,$number2);
echo "$answer";

which might make things slightly easier to understand.

A system that can be used to manage the content of a website is called content management system (CMS). In other words, CMS is a tool to create, edit, and remove details/information in a website.

As you know we are all fond of the easy things in life. We all like the path of least resistance. The easier we can find our way the better for us. The more complicated something appears the less we understand it and as consequence the less we like it.

With this in mind we need to approach the building of a website in a way that will avoid all of the above. Your website will need to be laid out in a way that understands the visitor's needs and addresses them clearly and concisely.

The question then becomes how to do this? When considering what subject to build your site around you will need to start your research on the forums relative to the topics of choice. For example if your passion relates to golf then you will need to visit forums where this subject is discussed.

Here you will need to look at what questions are being asked and where the people posting to this forum are having difficulty. Then you will need to get engaged and try and help. Here is how you could do this. Create a signature that links back to a free blog that asks the question "what is the biggest problem you face when it comes to golf"

On your free blog you could ask other questions. Your blog then can have a form where people can submit their questions. Of course you would need to offer them something to do this that will help their game and of course you will need to offer it for free.

Based on this you will be gathering actionable intelligence relative to your target market. With this information you can then build a website that addresses these concerns and provides a product that you are either affiliated with or that you have created yourself.

Now that you have this information you can build a real website that can generate a real income in multiple ways. You will want to build a site that is structured properly for the search engines and one which is easy to navigate for your visitors.

To conclude if you lay the groundwork properly then the rest will fall into place.
