A beginners tutorial
in PHP
By Bally Chohan

Step 1:
 To use PHP you’ll need a server to work
on and test your page…
 You may already have web space with
PHP installed to work on,
 Or you may already have a server
installed on your system,
 If not you’ll need to install one yourself….
- Bally Chohan

Installing a server:
 An easy way to aquire an Apache server,
along with PHP and MySQL built in (you’ll
need these when using PHP), is using
 WAMP (Windows) or,
 MAMP (Mac) (http://www.mamp.info)
 LAMP (Linux)
You can download WAMP at
http://www.wampserver.com/en/
- Bally Chohan

Step 2:
 Once you have followed the online instructions
for installing and configuring WAMP, you need to
check it works!
 Open notepad (php can be added straight into
your html) and type:
<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php echo '<p>Hello World</p>'; ?>
</body>
</html>
- Bally Chohan

Testing:
 Save this as ‘hello.php’ in your ‘www’ folder
located within your WAMP folder.
 This can be done by selecting ‘all files’ when
saving rather than the default ‘.txt’
 (Note: you can also just type this script straight
into a new document in Dreamweaver if
preferred)
 Now preview by opening your browser and
entering http://localhost/hello.php
 Your page should look like this…

Step 3: Variables
 Variables will allow a value to be changed
throughout your page without having to go
through and find it every time you need it
changed.
 A variable can be defined by using ‘$’ at the
beginning of your variable name. e.g.
$variable = ‘value’
 A variable must start with a letter or underscore
and can only contain letters, numbers or
underscores, and must not use spaces
- Bally Chohan

Variables: a simple example
<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php
$weather="sunny";
echo 'Hello World it’s ';
echo $weather;
?>
</body>
</html>
Note: every line of PHP must end in ‘ ; ’ - Bally Chohan

The result should look like this:

Now to experiment!
