I was inspecting a class of a phpoffice vendor called phpspreadsheet and found the following function in the module Calculation.php... is not really a problem, but I would like to understand the meaning of this function, I program in php at 10 years and have never seen 3 points within a function parameter. I would like to know what this means, what cause or what it serves! Follow the function
private static function mkMatrix(...$args)
{
return $args;
}
