In the following line from the video, Hampton used a dot:
return "Product Name: ". $this -> name;
I am not sure we have covered it yet (I could be wrong).
What does it do?? Why is there a space after it??
Thanks Leon

The whitespace is only to improve readability. (And I think people usually put a space both before and after, am I wrong?)

The . concatenates strings and the space is to aid legibilty in the code!

Python Web Development Techdegree Student 4,979 Pointsis it same if we say like this ?
return "Product Name: $this -> name";
so at here we don't need concatenates again
