Last time I talked about PHP and how to start moulding yourself into becoming a great PHP artist, Today I want to discuss PHP’s closest confidant and helper called Code-Ignitor
Code ignitor developed by British Columbia institute of technology was released in February 28, 2006.
It is an open source rapid development web framework which means code ingitor is really great at making
dynamic websites with php with high levels of quality, speed and efficiency

Points to Remember
- The name of the controller class must start with an uppercase letter.
