Sorry, the visibility in both _foo definitions must be protected, not
private.

Description:
------------
If you have an abstract method inside an abstract class (obvious) and
you call that method inside another non-static method within the class,
you get an error.
If this is an abstract class, it is suposed that a non-static method
defined in the class, may have been called from an instance of a child
class of that class (cause this class is abstract), and this child
class may not be abstract, to be instantiated. So the abstract method
have must been overloaded in the non-abstract child class and the call
in the non-static method must be valid.
I encountered a waste solution, making a reference to $this in the
marked lines, so the error is not be triggered.
If we substitute the marked line with:
$aux_this=&$this;
$aux_this->_foo();
The error doesn't appear.
Sorry for my english, if it is embarrasing.
Reproduce code:
---------------
<?php
abstract class A {
public function foo() {
$this->_foo(); // THIS LINE IS MARKED ;)
}
private abstract function _foo();
}
class B extends A {
private function _foo(){
echo "foo!!";
}
}
$b=new B();
$b->foo();
?>
Expected result:
----------------
foo!!
Actual result:
--------------
Fatal error: Cannot call abstract method A::_foo() in myphp.php on line
4
