Let's get into it Partner.

In the last tutorial of the series; 'Build Your Own Site', we elaborated a lot more on HTML, and helped built our first Form on an HTML Page. We talked a little about submitting forms and needing PHP to process that form submission. And so here we are; learning some of that PHP "good-good" to get you start.

Now that we have talked extensively about how all of this is going to work, let's get back to the topic at hand shall we; learning how to use the PHP language.

PHP Tags

As we've indicated in a lot of our previous tutorials, PHP is written between php tags, like so:

<?php  exit('soul train'); //php here  ?>
<!DOCTYPE HTML>
<html>
<head>
<title>PHP FOOL!!</title>
</head>

<body>
    php above fool
</body>

</html>
<?php
    echo 'hello world';
?> 
DECLARING VARIABLES

Variables in PHP are declared with the $ sign, because we're all about that moolla booiiyyy. Naaahh it's just a convention that was adapted at the creation of the language. Look at the example below

<?php 
    $stuff = "Hello World";
    echo stuff;
?>
<?php 
    $stuff = "Hello World";
    echo $stuff;

    $stuff = "New value";
    echo $stuff;
?>
<?php 
    $stuff = "Hello World";
    echo "At first you have to say ".$stuff;
?>
<?php 

    $num = 5;

    $sum = $num + 5; // this will give 10

    $difference = $num - 2; // this will give 3

    $multiplication = $num * 2; // this will give 10

    $division = $num / 1; // this will give you 5

?>

We'll be using a lot of PHP variables in these tutorials, so please look at these basic PHP variable rules below.
