ID: 61909 Comment by: david at panmedia dot co dot nz Reported by: david at panmedia dot co dot nz Summary: PHP realpath on Windows Case Issue Status: Not a bug Type: Bug Package: Filesystem function related Operating System: Windows Vista/7 PHP Version: Irrelevant Block user comment: N Private report: N New Comment: @pajoye, you missed my point about realpath not resolving the correct link target if the case is different. See my first comment. Previous Comments: ------------------------------------------------------------------------ [2012-05-03 05:51:04] paj...@php.net We do not support case sensitive paths on windows, so do 99.999% of the windows apps as well. strcasecmp is what you actually need. ------------------------------------------------------------------------ [2012-05-03 03:16:50] david at panmedia dot co dot nz @larue...@php.net Well, not always. In Windows Server 2008 it can be configured. http://technet.microsoft.com/en-us/library/cc725747.aspx Also, the point of realpath is to return the canonicalized absolute pathname, but it does not. Especially in the case of nested symlinks, as I pointed out in my other comment. You should be able to test if a path is the same by going if (realpath('c:\path-to-link') === realpath('C:\RealPathToTarget')) ... ------------------------------------------------------------------------ [2012-05-03 03:10:56] larue...@php.net path in windows is case insensitive.. ------------------------------------------------------------------------ [2012-05-02 17:46:25] david at panmedia dot co dot nz On further investigation I have noticed that on Windows symlinks are only followed 1 level deep: // F:\>mkdir link-target // F:\>mklink /D link f:\link-target // F:\>mklink /D link2 f:\link $dir = realpath('f:\link2'); var_dump($dir); $dir = realpath($dir); var_dump($dir); $dir = realpath($dir); var_dump($dir); // string 'f:\link' (length=7) // string 'f:\link-target' (length=14) // string 'F:\link-target' (length=14) ------------------------------------------------------------------------ [2012-05-02 17:37:52] david at panmedia dot co dot nz Description: ------------ I have a symlink on my Windows server which was made like this: F:\>mkdir link-target F:\>mklink /D link f:\link-target (Note the lower case f: in the symlink target) In PHP I run this: $dir = realpath('f:\link'); var_dump($dir); $dir = realpath($dir); var_dump($dir); Which outputs: string 'f:\link-target' (length=14) string 'F:\link-target' (length=14) Notice the change in case on the second realpath. The expected output is: string 'F:\link-target' (length=14) string 'F:\link-target' (length=14) Test script: --------------- <?php // F:\>mkdir link-target // F:\>mklink /D link f:\link-target $dir = realpath('f:\link'); var_dump($dir); $dir = realpath($dir); var_dump($dir); Expected result: ---------------- string 'F:\link-target' (length=14) string 'F:\link-target' (length=14) Actual result: -------------- string 'f:\link-target' (length=14) string 'F:\link-target' (length=14) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61909&edit=1
