I assume this is expected bahvior. At least on UNIX/Linux systems stat
is defined as
The stat() function obtains information about the file
pointed to by path. Read, write, or execute permission of
the named file is not required, but all directories listed
in the path name leading to the file must be searchable.
I assume it is similar on Windows.
If the zip extension is accessing the temp dir this should probably be
documented.
Assigning to Pierre who knows zip and windows better :-)

Description:
------------
On Windows 2003, IIS we use php as CGI. The php process runs as a
IUSR_XXXX user. When we want to unzip a file, we get error 11
(ZIP_ER_OPEN).
I tracked this by Process Monitor and I saw that ZipArchive::open()
tries to list a directory. We use temp directory. On Windows 2003 it is
C:\Windows\Temp.
After listing this directory ZipArchive::open() returns 11. And doesn't
continue at work.
When I add right "List Folder" for user IUSR_XXXX the open() call
succeeds.
I think it should be a kind of bug of c-runtime. I searched for
ZIP_ER_OPEN in php source and this is returned nearly after calls of
fopen() and stat(). It's odd that fopen() and stat() makes directory
listing....
Test script:
---------------
//without result testing:
$zipfile = tempnam(sys_get_temp_dir(),'zip');
file_put_contents($zipfile, $a_zip_file_content);
$zip = new ZipArchive();
$a_zip_file_content_reread = file_get_contents($zipfile,
$a_zip_file_conent);
//$a_zip_file_conent_reread has bean successfully read and has the same
content as $a_zip_file_content
$res=$zip->open($zipfile);
if ($res!==true)
echo "Failed open a file: ".$res;
