Hi there, Luca,

Yes I think you've got it right, var dump is a pre build PHP function that displays the contents including the type of variable.

So you could use it to inspect the contents of an array, or a variable or an object.

As i recall the output would be something like this

one[0], => two[1]

It's just a list of what makes up a particular object. :-)
