Description:
------------
The documentation of ReflectionFunctionAbstract::getParameters indicates that the return value is "The parameters, as a ReflectionParameter object.". Of course, since a ReflectionParameter object is just reflecting one single parameter, it cannot return all of them as a single of those objects.
Testing reveals that ReflectionFunctionAbstract::getParameters returns an _array_ of ReflectionParameter objects (more or less as expected).

I tested this on php 5.2.9, but whether or not this behavior has changed in newer versions shouldn't matter as the documentation would still be incorrect.

Reproduce code:
---------------
class Test
{
        public function AFunction($x, $y, $z)
        {
                $this->AnotherFunction($z, $x, $y);
        }
}


$r = new ReflectionMethod('Test', 'Afunction');
$p = $r->getParameters();
var_dump($p);

Actual result:
--------------
array(3) {
  [0]=>
  &object(ReflectionParameter)#2 (1) {
    ["name"]=>
    string(1) "x"
  }
  [1]=>
  &object(ReflectionParameter)#3 (1) {
    ["name"]=>
    string(1) "y"
  }
  [2]=>
  &object(ReflectionParameter)#4 (1) {
    ["name"]=>
    string(1) "z"
  }
