Greetings all,

When a private function is called from within a class, it is exposed in the print_r() (or var_dump()) output on it's object.

In order to explain this, consider this code:

class foo
{
    private function sayFoo()
    {
        /* uncomment this line */
        //$this->doSomeFoo();
    }
    private function doSomeFoo()
    {
        echo "Doing some foo\n";
    }

}

$foo = new foo;
// print the structure of $foo
print_r($foo);
// var_dump($foo);
Initially, this will return

foo Object
(
)

Which is correct.

However, if you then uncomment the line in "sayFoo", the print_r will return the name of the private function as one of the array indexes.

Changing the scope of "sayFoo" does the same thing no matter what scope you use.

I'm pretty sure this isn't expected behaviour, as that would expose the private function's existance (even though they still can't be accessed).

Tested on:
PHP 5.0.0-dev, 200305061830 build, Win32 package.
