Just for those who found this thread on Google.

In PHP 5.6 and above you can use ... to specify the unknown number of parameters:

function sum(...$numbers) {
    $acc = 0;
    foreach ($numbers as $n) {
        $acc += $n;
    }
    return $acc;
}

echo sum(1, 2, 3, 4); // 10

$numbers is an array of arguments.
