My idea for the PHP development as a difficult course was wrong and I came to know that when I joined It and Dc and got the training. Then I came to know that this is an interesting subject and I started enjoying it. Now I own my websites and am happily developing them on my own. I like this work and am grateful to the training for showing me the way.
