Description:
------------
i want to make zip with password. 
But i think zipArchive::setPassword don't work.
When using setPassword that making protected zip. right?
so, i want to reply mail about that. thank.

Test script:
---------------
$zip = new ZipArchive ();
$file = "1.txt"; 
$zipPath = 'test.zip';
if (($zip->open ( $zipPath, ZipArchive::CREATE)) == true) {
	
	$z = $zip->addFile ( $file );
	if($z !== false){
		//var_dump($z);
	}
	$a = $zip->setPassword('abc');
	$zip->close ();
	echo "okey";

Expected result:
----------------
Created ZIP archive should have a password protection, and when opening it on a local machine with WinZIP, the program should ask for the password prior to open the archive.
