What Do I Need?
To start using PHP, you can:
- Find a web host with PHP and MySQL support
- Install a web server on your own PC, and then install PHP and MySQL
Use a Web Host With PHP Support
If your server has activated support for PHP you do not need to do anything.
Just create some .php files, place them in your web directory, and the server will automatically parse them for you.
You do not need to compile anything or install any extra tools.
Because PHP is free, most web hosts offer PHP support.
Set Up PHP on Your Own PC
However, if your server does not support PHP, you must:
- install a web server
- install PHP
- install a database, such as MySQL
Note: The official PHP website (PHP.net) has installation instructions for PHP: http://php.net/manual/en/install.php

JavaScript syntax is the set of rules, how JavaScript programs are constructed.
JavaScript Programs
A computer program is a list of "instructions" to be "executed" by the computer.
In a programming language, these program instructions are called statements.
JavaScript is a programming language.
JavaScript statements are separated by semicolons.
Example
var x = 5;
var y = 6;
var z = x + y;JavaScript Statements
JavaScript statements are composed of:
Values, Operators, Expressions, Keywords, and Comments.
JavaScript Values
The JavaScript syntax defines two types of values: Fixed values and variable values.
Fixed values are called literals. Variable values are called variables.
JavaScript Keywords
JavaScript keywords are used to identify actions to be performed.
The var keyword tells the browser to create a new variable:
var x = 5 + 6;
var y = x * 10;JavaScript Comments
Not all JavaScript statements are "executed".
Code after double slashes // or between /* and */ is treated as a comment.
Comments are ignored, and will not be executed:
var x = 5; // I will be executed
// var x = 6; I will NOT be executedLet's test yourself with Khmer-WEB!

JavaScript does NOT have any built-in print or display functions.
JavaScript Display Possibilities
JavaScript can "display" data in different ways:
- Writing into an alert box, using window.alert().
- Writing into the HTML output using document.write().
- Writing into an HTML element, using inner HTML.
- Writing into the browser console, using console.log().
- Using window.alert()
- You can use an alert box to display data:
Example
<!DOCTYPE html>
<html>
<body>
<h1>My First Web Page</h1>
<p>My first paragraph.</p>
<script>
window.alert(5 + 6);
</script>
</body>
</html>Using document.write()
For testing purposes, it is convenient to use document.write():
Example
<!DOCTYPE html>
<html>
<body>
<h1>My First Web Page</h1>
<p>My first paragraph.</p>
<script>
document.write(5 + 6);
</script>
</body>
</html>Using document.write() after an HTML document is fully loaded, will delete all existing HTML:
Example
<!DOCTYPE html>
<html>
<body>
<h1>My First Web Page</h1>
<p>My first paragraph.</p>
<button onclick="document.write(5 + 6)">Try it</button>
</body>
</html>Using inner HTML
To access an HTML element, JavaScript can use the document.getElementById(id) method.
The id attribute defines the HTML element. The innerHTML property defines the HTML content:
Example
<!DOCTYPE html>
<html>
<body>
<h1>My First Web Page</h1>
<p>My First Paragraph</p>
<p id="demo"></p>
<script>
document.getElementById("demo").innerHTML = 5 + 6;
</script>
</body>
</html>Using console.log()
In your browser, you can use the console.log() method to display data.
Activate the browser console with F12, and select "Console" in the menu.
Example
<!DOCTYPE html>
<html>
<body>
<h1>My First Web Page</h1>
<p>My first paragraph.</p>
<script>
console.log(5 + 6);
</script>
</body>
</html>Let's test yourself with Khmer-WEB!
