$name and $$name both are variables but with a single difference that is $name is just a normal php variable where as $$name is known as reference variable. It allow you to use $name variable's value as a variable for getting $$name variable value.
$name = 'Roshan';
$$name = 'Singh';
echo $name . "<br>";
echo $$name . "<br>";
// value of "$name" variable
echo $Roshan
//output
Roshan
Singh
Singh // This is value of "$Roshan" variable
