Dereferencing confusion? What is this example here called?
- by perf
Considering this PHP example:
class A
{
public function getB( )
{
return new B();
}
}
class B
{
public function test( )
{
echo "Hello";
}
}
I could use this:
$a = new A( );
$b = $a->getB( );
$b->test( ); // Hello
Or this:
$a = new A();
$a->getB( )->test( ); // Hello
Taking a closer look at the second example...
What is the name of this form of expression?
Does this have something to do with dereferencing?
In which programming languages is this available?
What other forms of this exist?
