What does these ... mean in this example?

Question

I'm learning PHP http://php.net/manual/en/migration70.new-features.php and in the following example, I don't understand ... prepended with the $ints parameter in the function definition.

<?php
// Coercive mode
function sumOfInts(int ...$ints)
{
    return array_sum($ints);
}

var_dump(sumOfInts(2, '3', 4.1));

Can anybody please tell me what those dots are for?

Thanks.

This allows you to have variable amount of parameters http://php.net/manual/en/functions.arguments.php $ints is an array. — Jason K, Dec 13 '17 at 17:04

that means that when you call that function, you can pass X integers and the function will process them, doesn't matter how many are they. If you call sumOfInts(3,4,6,2,9) or sumOfInts(3,2,9), the function works, no matter how many arguments you pass
