Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to

You can increase visibility in derived classes (e.g.,
protected->public) but you can not decrease visibility (since it
violates the base class API).

Description:
------------
if a protected data member is re-declared as public in a child class,
it is redefined as public. Shouldn't the parent class protected
declaration override the child class as it does for private?
Reproduce code:
---------------
<?php
class test
{
protected $a = 6;
function __construct()
{
print $this->a;
}
}
class my extends test
{
var $a = 7;
function __construct()
{
print $this->a;
parent::__construct();
}
}
$a = new test; // 6
$a = new my; // 77
print $a->a; // should give error, is 7
$a->a = 4;
print $a->a; // 4
?>
Expected result:
----------------
Fatal Error, cannot redeclare a protected data member as public
Actual result:
--------------
67774
