-> is use when working with objects.
It's the equivalent of " . " in java or javascript.
It's how you access a method/function or property/value that belongs to (is inside of) the object.
In javascript:
var node = document.getElementById('header');
In php:
$dom = new DOMDocument();
$node = $dom->getElementById('header');
