project has no copyright statement, and is an unattributed derivation of php's openssl support

There is no copyright statement on lua-openssl, so under most legal jurisdictions, it is copyright the author, all rights reserved, and cannot be legally used without some kind of agreement with the author. This probably isn't what you intended by putting the source on github.

Also, this project looks like it was started from a copy of PHP's openssl support. That's OK, except this isn't acknowledged anywhere that I can see, and the original authors copyright statements have been stripped from the code. The PHP copyright explicitly prohibits that:

http://www.php.net/license/3_01.txt:

modification, is permitted provided that the following conditions
are met:

Hello
I add MIT license, and acknowledgement steal some idea and code from php, Please see https://github.com/zhaozg/lua-openssl/blob/master/LICENSE.

Good start, but the original C files had copyrights on the top that said effectively "you can use this code, but you cannot remove this copyright from the top of this file".

You need to restore all those statements if you ever want this project to get used by people who care about copyright (like most linux distributions or companies).

That's not a problem, I'll fix it, I need take more attention on copyright.

Hi, I do some research.
If I'm not wrong, I need to add then below text on the top of file:

 "This product includes PHP software, freely available from <http://www.php.net/software/>".

Is that only thing need to do?

Add PHP license on top of file.
