What does "->" do or mean in PHP?

Question

I have seen this at a lot of place but have never understood it's meaning or working... for example:

// Registry
$registry = new Registry();

// Loader
$loader = new Loader($registry);
$registry->set('load', $loader);

If someone can elaborate this, I will be very greatful... thanks in advance...

Answer 1

That calls a method on an instance of a class or accesses a field of an instance of a class. You may find this page useful.
