From PHP 5.6 we now have the possibility to invoke or declare a function, stating that the arguments are infinite, using the ... operator.

Example:

function add(... $arguments)
{
    return array_sum($arguments);
}

add(1, 2, 3); // imprime: 6

Example 2:

print_r(...[$object, false]);
// é equivalente a:
print_r($object, false);

I asked a question related to variadic functions where the advantages of using it are explained.

But I do not know the name of this operator used in variadic funcion , that of the ... operator.

I often talk with reluctance. But I do not know if I'm right.

What is the correct name for this operator?
