Basically, "->" use to reference variables or functions (or more
precisely members and methods) within a class.
eg:
class Something {
public $a = 'Hello';
function __construct($a)
{ $this->a = $a; }
function SetA($a);
{ $this->a = $a; }
function GetA()
{ return $this->a; }
} //end class

Now the member "a" and methods SetA , GetA can be accessed via the "->"
operator
$obj = new Something('World');

//Access method "GetA" of object "obj" using ->
print $obj->GetA();

//accessing member "a" of object "obj" using ->
$obj->a = 'Hello';
print $obj->a;
