What is this -> in PhP?

Question

-> was not there in the lessons xD

Answer 1

-> is not related to arrays, it's for object scope.
class doSomething{
private $correctAnswer;
function somethingDone($somethingHappened){
$this->correctAnswer = $somethingHappened;
}
}

$ds = new doSomething();
$ds->somethingDone(true);

Answer 2

Ok thanks,

Answer 3

Whenever you want to use an object’s method or property, you need to use the -> operator.
e.g.:
$company->name = 'Acme';
$company->getName();
