Can Anyone Guide...........

I was/still in a similar situation to you. I'd say a few things:

1) Get a decent overview of PHP first. Get a book on it, and follow some basic PHP tutorials until you understand the syntax, and can do some very simple projects.
2) Read up on the MVC logic. This is the biggest barrier to learning CI I feel from a newbie point of view. When you understand that relationship it will all just 'click' for you and you'll find writing PHP any other way is extremely inefficient.
3) Make sure you read every tutorial that you can find I'm working through the list on <a href="http://codeigniter.com/wiki/Tutorials/">http://codeigniter.com/wiki/Tutorials/</a> at the moment.

I hope that helps.
