// $fruit stores the value 'apple', so $$fruit will refer to the variable with name apple i.e., $apple.

No Luka this was correct , this is variable variables and answer is correct. i check my note now and this was absolute correct . With PHP, you can use one variable to specify another variable's name.
So, a variable variable treats the value of another variable as its name
. <?php
$a = 'hello';
$hello = "Hi!";
echo $$a;
?>
Please write comments carefully in the future before you deslike someone note . Good luck
