New Comment:
You call the parent's constructor in the child, of course it sets the
variable again. (this is 'fixed' in PHP 5 with the introduction of
private/protected/public variables)

Description:
------------
I define variable A within parent class cFoo, and initialise it within
the class Constructor.
I redefine variable A within child class cBar, and initialise it within
the class Constructor which then calls the parent class Constructor.
The parent constructor modifies the child instance of property A rather
than the parent instance.
Reproduce code:
---------------
<?php
/* Inheritance test2. Inherited Vars */
class cFoo
{
var $A;
function cFoo() /* constructor */
{
$this->A = "cFoo_A";
}
function Display()
{
print("Within cFoo::Display; property A = '$this->A'; should be
'cFoo_A'<br>\n");
}
};
class cBar extends cFoo
{
var $A; // redefines A
function cBar() /* constructor */
{
$this->A = "cBar_A";
$this->cFoo(); /* parent constructor */
}
function Display()
{
print("Within cBar::Display; property A = '$this->A'; should be
'cBar_A'<br>\n");
}
};
$foo1 = new cFoo;
$foo1->Display();
$bar1 = new cBar;
$bar1->Display();
exit;
?>
Expected result:
----------------
Within cFoo::Display; property A = 'cFoo_A'; should be 'cFoo_A'
Within cBar::Display; property A = 'cBar_A'; should be 'cBar_A'
Actual result:
--------------
Within cFoo::Display; property A = 'cFoo_A'; should be 'cFoo_A'
Within cBar::Display; property A = 'cFoo_A'; should be 'cBar_A'
