Today I discovered a possible serious problem with the way the latest
PHP versions handle private properties.

Given the following code:

<?php

class Base
{
private $var1 = 0;
}

class FinalClass extends Base
{

function Test()
{
$this->var1 = 10;
}
}

$c = new FinalClass();

$c->Test();

print_r( $c );

?>


I get the following result:

FinalClass Object
(
[var1:private] => 0
[var1] => 10
)


Now... PHP should have displayed an error when I was trying to set a
value to this private member from the parent class. No error message was
displayed. It created a local member which holded the value 10. But when
trying to access this value from the parent class, it is not there.

I think PHP should notify of the problem but it is not doing so. I have
my error reporting level on E_ALL.

Any ideas?
