Operating system: Windows 2003
PHP version: 5.1.6
PHP Bug Type: Directory function related
Bug description: is_dir seem to have permission problems
Description:
------------
If you have a directory where Everyone has "Full Control" rights you would
expect is_dir to return true but it doesn't.
This bug has existed since 5.0.0 and I've had this problem on at least
three servers during the past year.
I'm lying about my PHP version (it's really 5.1.4) but I've checked the
change log.
realpath() seem to exhibit the proper behavior.
Reproduce code:
---------------
<?php
print("<pre>");
error_reporting(E_ALL);
#clearstatcache();
$paths = array(
"C:\\",
"C:\\Windows",
"C:\\Windows\\Temp",
"C:\\Windows\\Temp\\RP_Compile",
"C:\\Windows\\Temp\\DoesNotExist",
"C:\\Windows\\Temp\\RP_Compile\\Subdir",
);
print("\nis_dir()\n");
foreach($paths as $path)
print(is_dir($path) . " \t$path\n");
print("\nrealpath()\n");
foreach($paths as $path)
print(!(realpath($path) === FALSE) . " \t$path\n");
print("\nstat()\n");
foreach($paths as $path)
print(!(stat($path) === FALSE) . " \t$path\n");
print("</pre>");
?>
Expected result:
----------------
is_dir()
1 C:\
1 C:\Windows
1 C:\Windows\Temp
1 C:\Windows\Temp\RP_Compile
C:\Windows\Temp\DoesNotExist
1 C:\Windows\Temp\RP_Compile\Subdir
realpath()
1 C:\
1 C:\Windows
1 C:\Windows\Temp
1 C:\Windows\Temp\RP_Compile
C:\Windows\Temp\DoesNotExist
1 C:\Windows\Temp\RP_Compile\Subdir
Actual result:
--------------
Notice the different result for "C:\Windows\Temp\RP_Compile"
is_dir()
1 C:\
1 C:\Windows
1 C:\Windows\Temp
C:\Windows\Temp\RP_Compile
C:\Windows\Temp\DoesNotExist
1 C:\Windows\Temp\RP_Compile\Subdir
realpath()
1 C:\
1 C:\Windows
1 C:\Windows\Temp
1 C:\Windows\Temp\RP_Compile
C:\Windows\Temp\DoesNotExist
1 C:\Windows\Temp\RP_Compile\Subdir
