$message is a simple variable and $$message is variable of a
variable(also known as dynamic variable).
For Example:
$message = "welcome";
$welcome = "to php programming tricks!!!";
echo $message; // Output: welcome
echo "<br>",$$message; // Output: to php programming tricks!!!
You will notice with the second echo it will check the
variable $message for it's value and it's value is the
string "welcome". So then it searches for $welcome and finds
the final value which it yields.
