A beginners tutorial in PHP By Bally Chohan

Step 1::

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::

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::

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::

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… - Bally Chohan

Step 3: Variables:

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:

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
