What does setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION) do more exactly?

Question

As the title says, i tried to understand the concept but it seems like with it or without it the result its the same. I tried to look into php manual and i kind of understand what says but in practice its just seems the result is the same.

Manual also says that

PDO::__construct() throws a PDOException if the attempt to connect to the requested database fails.

This is your case exactly. And it has nothing to do with PDO::ERRMODE_EXCEPTION.

To test PDO::ERRMODE_EXCEPTION - properly connect to an existing database and run an invalid query.
