setBlock help PLSSSSSSSSSSS

I am trying to use the function $level->setBlock(), but I am not sure what parameters to use.
For example, when a player destroys a block at (new Vector3(X,Y,Z)), how do I turn the block at (new Vector3(X,Y,Z+1)) to air?
I know I should use

PHP:

$level->setBlock(new Vector3(X,Y,Z+1), $block)

, but how do I make a block?
I tried

PHP:

new Block(0)

, but error dump said Block cannot be instaniated.

PLEASE HELP.

Usage:

Code:

$air = BlockAPI::get(0, 0);
$level->setBlock(new Vector3($x, $y, $z + 1), $air);

Where the first 0 in the Block API is the air block ID, and the second 0 is the binary indicator, which is usually not used.
The rest is pretty much self-explanatory.

thx

So the second parameter is saying whether it is in denary? Can I omit it?

If you mean the parameters of BlockAPI then yes you are right, you can leave it at 0. Don't completely leave it out though, just set it to 0.
