Bug #55832 [Bgs]: is_file() returns true if file does NOT exist

Edit report at https://bugs.php.net/bug.php?id=55832&edit=1 ID: 55832 Updated by: pajoye@php.net Reported by: christian dot koncilia at gmx dot net Summary: is_file() returns true if file does NOT exist Status: Bogus Type: Bug Package: Filesystem function related Operating System: Windows 7 PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: This is a wrong explanation. It is by no mean due to the Win32 API idiosyncrasy but the usage of FindFirstFile. Its behavior is clearly documented (http://msdn.microsoft.com/en- us/library/windows/desktop/aa364418(v=vs.85).aspx) and we should actually stop to use it in realpath and related functions. By doing so we also have to do the case conversion manually as well (btw, amazing that we have to do that for the case insensitive filesystem ;). However, I keep this bug as bogus as we already have a feature request to solve this problem.

This is an idiosyncrasy of the windows API. ------------------------------------------------------------------------ [2011-10-02 14:12:01] christian dot koncilia at gmx dot net Description: ------------ Using Windows 7, create a directory "C:\dirtest\Au". Run the test script. Output produced is: bool(true) bool(true) bool(false) bool(false) bool(false) bool(false) although neither $file1 nor $file2 exist! Expected output would be "bool(false)" in all cases. Test script: --------------- <?php $file1 = 'C:\dirtest\Au\aux.gtb'; $file2 = 'C:\dirtest\Au\bux.gtb'; var_dump(is_file($file1)); var_dump(file_exists($file1)); var_dump(is_readable($file1)); var_dump(is_file($file2)); var_dump(file_exists($file2)); var_dump(is_readable($file2)); Expected result: ---------------- bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) Actual result: -------------- bool(true) bool(true) bool(false) bool(false) bool(false) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55832&edit=1
