Body
Efficient learning-(analysis of causes, formation methods)

Let's start by analyzing:

Novice may take the move?
I use ' degree Niang ', ' elder brother ' Encyclopedia PHP, found that although the concept surface know, but the concrete operation or confused, dazed, distant
II use ' degree Niang ', ' elder brother ' to look for various resources , collect, organize, archive and then, then, put it in memory (this is true)
III Start watching video tutorials, and not long, various grammars, explosions
/**

*/
Personally think that the above practices have several misunderstandings, do not step
I find a good information (rest assured: I will put some) insist on thoroughly understand , do not ask for information how much, do not support the data looked and changed
