What exactly does -> do in php?

I have a good understanding of the basics of php but never understood this. I tend to see in apps that use Codeignitor.

Answer 1

It accesses accessible child methods or properties of objects:

class myClass {
  public $fizz = 'Buzz';
  public function foo() {
    echo 'Bar';
  }
}

$myclass = new myClass();
$myclass->foo(); // outputs 'bar'
$myclass->fizz = 'Not Buzz'; // overwrites $fizz value
