Null Coalescing Operator ( ?? ): The null coalescing operator provides a convenient way to choose between two values: A ?? B returns A if A is not null , otherwise returns B. It’s often used to provide default values when dealing with potentially undefined or null variables (e.g., reading from $_GET or arrays). This is effectively a shorthand for isset(A) ? A : B .

$username = $_GET["user"] ?? "Guest";
echo $username; // Outputs the 'user' query param if set, otherwise
"Guest"
$nick = null;
echo $nick ?? "anonymous"; // Outputs: anonymous (since $nick is null)
