Can I put an array inside a Mysql query?

No, you can't. Furthermore, you should not do this. It's violating first normal form.

Each value should have its own column if there are a fixed number of values. If there are not a fixed number, you should have an intermediate table to handle the many-to-many relationship.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
