title: What does these ... mean in this example?
body: <p>I'm learning PHP <a href="http://php.net/manual/en/migration70.new-features.php" rel="nofollow noreferrer">http://php.net/manual/en/migration70.new-features.php</a> and in the following example, I don't understand <code>...</code>  prepended with the <code>$ints</code> parameter in the function definition.</p>
  
  <pre><code>&lt;?php
  // Coercive mode
  function sumOfInts(int ...$ints)
  {
      return array_sum($ints);
  }
  
  var_dump(sumOfInts(2, '3', 4.1));
  </code></pre>
  
  <p>Can anybody please tell me what those <strong>dots</strong> are for?</p>
  
  <p>Thanks.</p>
