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.

Any of us who are interested in making money online are bombarded daily with information relative to achieving this objective. Along with this it seems that everyday there is a new technique and if you do not apply it you could be leaving thousands of dollars on the table.

Many of these opportunities involve creating your own website. This way you can earn revenue using multiple techniques. And of course on the business opportunity sales pages they often say that this can be done within weeks of implementing their strategies.

While in some cases this may be true it is often more the exception rather than the rule. I do not want to burst anyone's bubble. I have been marketing online for almost four years and honestly it takes grit and determination to build a successful business on the internet.

The truth is it can be done but many factors have to be brought into consideration before you begin. The first being how many hours per day are you willing to spend to build your online business.

By the way do not be fooled into thinking that an online business does not have to be taken as seriously as an offline business. If you do not take it seriously then you will not achieve serious results.

The step to take is to outline on a piece of paper what your interests are. Then you will need to research the market online to see which way you can enter the market and make money.

In terms of building a website you need to gather all this information first. Once you find what you are looking for and have determined that you are going to build a site relative to that subject you can then look for a site builder that will help you achieve the results you desire to achieve.

The best site builders are the ones that have proven results. Secondly if you are not technically minded you want it to take care of all those details. Remember if you are busy building a site then you will not be marketing your website hence you will not be making money.

To conclude apply due diligence. Research your market thoroughly and you will achieve results.
