Operating system: Windows 2000
PHP version: 4.3.3
PHP Bug Type: Filesystem function related
Bug description: fileperms() inaccurately reports permissions
Description:
------------
On Linux, PHP 4.3.3 correctly returns file permissions from the
filesystem. With Windows 2000 and IIS, PHP in CGI or ISAPI mode does not.
The reproduce code assumes that another file (TEST.PHP) already exists in
the filesystem. Any other file or directory could be used (although the
permissions are returned differently for directories). TEST.PHP can have
any permissions, including explicitly DENY "Full Access" for EVERYONE
group.
Reproduce code:
---------------
<?php
clearstatcache();
$test = fileperms('c:/inetpub/wwwroot/test.php');
echo '<H1>PERMS = ';
$read = ($test & 0x0004) ? 'r' : '-';
$write = ($test & 0x0002) ? 'w' : '-';
$execute = ($test & 0x0001) ? 'x' : '-';
echo $read.$write.$execute.'</H1>';
?>
Expected result:
----------------
For files, returned results should be "<H1>PERMS = r--</H1>' if
permissions were set to READ. Returned results should be "<H1>PERMS =
rw-</H1>" if permissions were set to READ/WRITE or READ/WRITE/MODIFY.
Returned results should be "<H1>PERMS = rwx</H1>" if permissions were set
to READ/EXECUTE/WRITE or READ/EXECUTE/WRITE/MODIFY or FULL CONTROL.
For directories, returned result should be similar (although permissions
on directory are more well-defined).
Actual result:
--------------
For files, returned results will always be "<H1>PERMS = rw-</H1>';
For directories, returned result will always be "<H1>PERMS = rwx</H1>';
Even attempting this operation on "C:/pagefile.sys" returned "<H1>PERMS =
rw-".
Curiously, when marking the file as "read-only" in the file properties
(not security tab), the returned results are "<H1>PERMS = r--</H1>" for
files and "<H1>PERMS = r-x</H1>" for directories.
