PHP version: 5.2.5
PHP Bug Type: Filesystem function related
Bug description: is_readable() returns incorrect result
Description:
------------
NT ACL Permissions can be modified in Windows by right clicking on the
file, going to properties, and security. Clicking the Everyone user and
hitting Deny Read, will prevent ANYTHING from reading, even if they have
READ permissions granted elsewhere.
is_readable() doesn't seem to care and thinks that all these files are
readable, when in fact they aren't. is_writeable() probably has the same
problem. Previous Bugs Identified with this have been closed: 41519.
Reproduce code:
---------------
$some_file = 'C:\\path\to\file.txt';
if(is_readable($some_file))
{
echo file_get_contents($some_file);
} else
{
echo "This file isn't readable";
}
Expected result:
----------------
With NTFS ACL Permissions set to allow reading:
*Contents of File*
With NTFS ACL Permissions set to disallow reading:
"This file isn't readable";
Actual result:
--------------
With NTFS ACL Permissions set to allow reading:
*Contents of File*
With NTFS ACL Permissions set to disallow reading:
Warning: file_get_contents(C:\\path\to\file.txt)
[function.file-get-contents]: failed to open stream: Permission denied in
C:\\path\to\script.php on line 4
