Seeting Autocomplete Notepad++

How to set up autocomplete in notepad++.
Here is  my article about this topics. Its base my experience when i was write code expecially  in php.

In notepad++ we choose setting menu, after that we choose preference menu, and it will popup a preference menu, and then we must select "Enable  auto-completion on each input". We have two option here, but for internal function autocompletion of php we prefer to choose "Function completion".

Briefly, Setting up process whould like this :

setting>preference>select "Enable  auto-completion on each input" > "Function completion".
