$message is a variable
$$message is Variable to Variable.

Example:
Suppose $var="Hello";
$message="var";

echo $message; will print var while echo $$message; will print Hello.

Thanks

$message in simple variable and $$message in refrence variable.
For example

$message="hello";
$$message=$message;

echo $$message;

//It will print hello on the screen

$message is a variable whereas $$message is a variable variable. The value for $message becomes a variable in itself when you add $ to $message and so on.
e.g,
$message="come";
$come="sit";
$sit="eat";
echo $message;
echo $$message;
echo $$$message;

it will print: comesiteat

$$message  - this is called as variables variable

see...

$message = "Welcome";
$$message = "World";

Now we can echo above strings like

echo $message.$welcome;

This weill print we "WelcomeWorld"

Note : variable's value can be act as variable
