All of my public plugins use a configuration file of some sort: https://github.com/dutok?tab=repositories

It's very simple once you get the hang of it

hmmm . how well this help me ?

Look at the function names and guess what they are and how to use them. (Creating these objects is at the Advanced level in Learning-PocketMine-Development)

Learn PHP about objects.

i really don't have time to guess . just give me the answer ( i know . sham at me . i am teacher and i don't know the basics of configs )

If you know objects, you should know where to find the code of (new Config("blah"))->get($key).

This would be educational for all of us.

Once again, my plugins use most of these functions. Look through the code, that's how I learned best.

Of course. There are only two ways to learn plugin development I can think of: looking at the source code and looking at the source code of others' plugins.

Use two ways together !

I'll give you a break though, configuration is kinda tough and the documentation isn't very clear.

Yes but instantiate config objects is easiest. I learnt it by looking at the BanItem plugin.

The hardest, in my opinion, is SQL (SQLite or MySQL). Queries can be difficult to form.

Correct. That's why I still don't understand SQLite3 databases in PHP even till now.

If you'd like to see the struggle I went through!! Haha

Teach me SQLite3! XD
(I really want to learn it, but I don't have time or effort to, because it looks hardly debugable, programs using it)
