Description:
------------
I am trying to unpack a Zip file.  Permissions on both the Zip file and the destination directory (which is the same directory as the Zip file is in) are set to 0777.

Running extractTo (zlib 1.2.3 installed) using code from example 1 at http://uk2.php.net/manual/en/function.ziparchive-extractto.php
including
	$zip->extractTo('/path/...../');

results in no return to the browser (and the Zip file not being unpacked).

Changing the above to

	$directory = '/path/...../';
	$zip->extractTo('$directory');

results in " Warning: ZipArchive::extractTo() [ziparchive.extractto]: Permission denied in /path/....../script_file_name.php on line 12 "

Again the Zip file is not unpacked.

Reproduce code:
---------------
<?php

	$zip = new ZipArchive;

	if ($zip->open('/path/...../xyz.zip') === TRUE)
	{
		$zip->extractTo('/path/...../');
    $zip->close();
    echo 'ok';
	}
	else
	{
    echo 'failed';
	}
?>

Expected result:
----------------
Echo 'ok' (or 'failed')
Zip file unpacked

Actual result:
--------------
Nothing returned to the browser.
Zip file not unpacked.
