Description:
------------
The new function setPassword seems not to work in my environment. The function returns TRUE, however no password is set to the archive.



This was also reported to 
http://stackoverflow.com/questions/24190502/ziparchivesetpassword-doesnt-set-a-password-to-my-newly-created-file 
for a different PHP 5.6 version on a different operating system.

Test script:
---------------
$zipFilePath = sys_get_temp_dir() . DIRECTORY_SEPARATOR . 'filename.zip';
$password = 'P455W0RD';
if (file_exists($zipFilePath)) {   unlink($zipFilePath); }
$zipArchive = new ZipArchive();
$zipArchive->open($zipFilePath, ZipArchive::CREATE);
if ($zipArchive->setPassword($password)) { echo 'OK' . PHP_EOL; }
foreach (range(1, 10) as $fileNumber) {
    $zipArchive->addFromString('file' . $fileNumber . '.txt', rand());
}
$zipArchive->close();


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.

Actual result:
--------------
When opening the archive with WinZIP, no password is required and you get all contents right away.
