I'm sorry, the example was wrong, this is the right example:
<?php
class ExampleSuperclass
{
private $foo;
function propertyExists()
{
return property_exists($this, 'foo');
}
}

class ExampleSubclass extends ExampleSuperclass
{

}

$example = new ExampleSubclass();
var_dump($example->propertyExists());
?>

Another more complete example here:
<?php
 
class ExampleSuperClass
{
    private $foo;
    static protected $bar;
 
    private function foo()
    {
    }
 
    public function propertyFooExists()
    {
        return property_exists($this, 'foo');
    }
 
}
 
class ExampleSubClass extends ExampleSuperClass
{
    public function methodExists()
    {
        return method_exists($this, 'foo');
    }
 
    public function propertyBarExists()
    {
        return property_exists($this, 'bar');
    }
}
 
$example = new ExampleSubClass();
var_dump($example->methodExists());
var_dump($example->propertyFooExists());
var_dump($example->propertyBarExists());

?>

In php 5.2.1 you get:
bool(true)
bool(true)
bool(false)

php bool 5.3:
bool(true)
bool(false)
bool(true)

expected result: 
bool(true)
bool(true)
bool(true)

Using class name instead of object shows the expected result. I'd guess (according to docs) it should be same in both ways though.
