What to apply for console in phpstorm?

Question

phpstorm

Good afternoon.
I saw an interesting tool for php developers on the screenshot. Some kind of console screwed to NotePad ++, which allows you to display the result of the written code in php.
If, for example, I write something.
echo "Hello/nworld!";
Then the console will display:
Hello
world!
What is this console? And how can a similar tool be attached to phpstorm under mac os?
