PHP 4 doesn't know what to do with this syntax but one of the changes in
PHP 5 is to let you use the return value of a function without assigning
it first. If your function/method returns an object you can call
methods of that object without assigning it to a variable first.
Ex: $obj->getOtherObj()->method();
