Bug description: Object instance variables not visible from within __toString()
Description:
------------
Hi folks,
When overriding __toString() to provide custom object to string conversion
it appears as though object level variables are not visible from within the
function.
This affects public, private and protected variables equally. Static
member variables and class constants are not affected.
Reproduce code:
---------------
class Foo
{
public $_myVar;
public static $_static = 'I am static.';
const MY_CONST = 'I am constant.';
function __construct()
{
$_myVar = 'A public variable.';
}
function __toString()
{
return
"Variables:\n".$this->_myVar."\n".Foo::$_static."\n".Foo::MY_CONST;
}
}
$foo = new Foo;
echo $foo;
Expected result:
----------------
Variables:
A public variable.
I am static.
I am constant.
Actual result:
--------------
Variables:
I am static.
I am constant.
