Looking at a script PHP at some point I came across this line
$valor = $_GET['id'] ?? 1;
What is the interpretation of this code? What does it do?
What is the function of the "??" operator (two questions) in PHP?

?? is known as null coalescing was added in the PHP 7 . Its functionality is to return the first operand if it exists and is not null otherwise the second returns.
The code in PHP 7
$valor = $_GET['id'] ?? 1;
Can be translated into PHP 5 as
$valor = isset($_GET['id']) ? $_GET['id'] : 1;

Same as in C # and other languages, this is #
$valor = isset($_GET['id']) ? $_GET['id'] : 1;
