bugs needs fix before 5.4.1

Hi,
From the NEWS file :

• . Fixed bug #55475 (is_a() triggers autoloader, new optional 3rd argument to + is_a and is_subclass_of). (alan_k)
  The 3rd argument is add to let user choose autoload or not, but not a string or not.
  so maybe we can make it more clear.

Hi Stas,

Just FYI.
Following bugs are needed to be fixed before 5.4.1, I think.

https://bugs.php.net/bug.php?id=61526
Which is right, doc or code?

Both. The parameter means that first argument (object) can be a string,
and if it is, it will be passed to autoloader to find the class. See bug
#55475 for the discussion.
If is set to false does it means the first parameter can't be string?
Can't we just make the last parameter to autoload=true|false.
if the first parameter is a string then try to find the class if not try autoloadding.

if string will not be a String Class in 5.* I think it's ok to do like this. eg: callable and many mixed paramter.

what do you think?

This is worse than isset($str[0][0]) issue.

Non-string offsets do not work in strings, because they don't make sense
in strings.

You're right.
I've read too many bug reports today and confused :)

<?php
class Super {}
class Sub extends Super {}

// By default, 1st parameter may be string and treated as class name.
var_dump(is_subclass_of('Sub', 'Super')); // true

// Explicitly allow string as class name
var_dump(is_subclass_of('Sub', 'Super', true)); // true

// Do not allow string as a 1st parameter, so false.
var_dump(is_subclass_of('Sub', 'Super', false)); // false
?>

Therefore, 3rd parameter works for "Not allowing class name", but
it cannot be used to restrict autoloading.

Am I missing something? I'll read the report Stas mentioned from now.

Hi!

If is set to false does it means the first parameter can't be string?

It can. But it won't be seen as a class name, but rather as a string,
that is not an object that is an instance of a subclass of anything, so
it will return false.

Can't we just make the last parameter to autoload=true|false.
if the first parameter is a string then try to find the class if not try
autoloadding.

We discussed all the solutions already and chose this one, please see
discussion on the list and the bug I've referred to. I see no point in
going through the same discussion again.
