php tutorial - By Bally Chohan

  1. 1. A beginners tutorial in PHP By Bally Chohan
  2. 2. 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
  3. 3. 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
  4. 4. 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
  5. 5. 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

  7. 7. 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
  8. 8. 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
  9. 9. The result should look like this:
