you are attemptting to call a protected constructor from a outside scope.
just like:
abstract class A {
protected function __construct() {
echo "A constructor\n";
}
}
class B extends A {
/* NO __construct() declared */
public function foo() {
echo "foo method";
}
}
new B();//PHP Fatal error: Call to protected A::__construct() from invalid context
if you want B have a non-protected constructor, you must redeclared it with 'public'.

Description:
------------
When a construct is not declared on a inherited class and it's declared on base
class as protected, an instantiation of the derived class inside another class,
causes a fatal accessibility error.
Test script:
---------------
abstract class A {
protected function __construct() {
echo "A constructor\n";
}
}
class B extends A {
/* NO __construct() declared */
public function foo() {
echo "foo method";
}
}
class C {
public $B;
function __construct() {
$this->B = new B(); // Produces an error because B has no construct declared.
}
}
$c = new C();
Expected result:
----------------
This behavior is not documented.
Actual result:
--------------
Error: document.php line 18 - Call to protected A::__construct() from context 'C'.
