PHP is a server side language, and its not like javascript which is a client side language.

Section I - Using PHP
You can run PHP in basically 4 differen't ways.

<%
// Code in here
%>

<script language="php">
// Code in here
</script>

<?
// Code in here
?>

<?php
// Code in here
?>

I prefer the last method "<?php". You also may see "<?" be called shorttags.

Section II - Comments
There are bascically two ways that I do comments within the PHP code, they are:

<?php
// This is a comment
?>

<?php
/* Comment Line 1
Comment Line 2
*/
?>

As you probably can tell, the /* */ combo provides a multi line commenting system, while // privides a single line comment.

Section III - Display HTML
There are two very common ways to display text/html onto the webpage, print and echo. I prefer echo over print.
Example Usage:
print "<b>This is my bold text</b>";
echo "<b>This is my bold text</b>";

You might notice the ; symbol after those lines, its required after every line that you process data.

Section IV - Variables
Heres an example of giving a variable a value:
$name = "Jon";
And using what you learned earier try making it say on the screen:
Your name is Jon

To display variables in echo's or print's do this:
echo "Your name is $name";
or
echo "Your name is " . $name;

Thanks for reading and I hope it helps. Please remember that this is only a Beginning Guide to some simple features of PHP.
