Step 1

• To use PHP youll 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 youll need to install one yourself.

Installing a server

• An easy way to aquire an Apache server, along
  with PHP and MySQL built in (youll 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/

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
• lthtmlgt
• ltheadgt
• lttitlegtPHP Testlt/titlegt
• lt/headgt
• ltbodygt
• lt?php echo 'ltpgtHello Worldlt/pgt' ?gt
• lt/bodygt
• lt/htmlgt

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
