How to learn CI

Hi Soeharyo.

The best way would be to first learn some basic programming. If you know nothing about programming, find a PHP environment and start learning these things --

• Variables and variable types.
  
• Conditional execution (IF-ELSE statements)
  
• Logical operations (this OR that AND the other)
  
• Operator precedence (why 2 + 2 / 2 equals 3 and not 2)
  
• Loops (doing the same thing over and over until something else happens)
  
• Arrays (a special kind of variable)
  
• Functions
  

You can install PHP on your own computer, but you can also find PHP that you can run online. Try this search link: https://www.google.com/search?q=run+php+online

After you learn some PHP by itself, then try to mix it in with your HTML. For example, you could try building some kind of calculator or converter on a website. This is simple and does not require a database.

And then I think you are ready to learn Codeigniter. By then, you will know PHP well enough that you can focus on how Codeigniter works instead of trying to learn programming, PHP, and Codeigniter all at the same time. Good luck and ask us for help whenever you need it!
