#37687 [NEW]: file_exists strange behavior on windows platform only

From: pear at laurent-laville dot org Operating system: Windows XP PHP version: 4.4.2 PHP Bug Type: Filesystem function related Bug description: file_exists strange behavior on windows platform only Description: ------------ Concat directory name without trailing dir separator, and a file name. While i was ready to prepare a new release of PEAR_PackageFileManager (PFM), and generate the new package.xml, i found a bug. I thought first it was from PFM, but then i investigate a bit more, and i found : It will occurs only under Windows platform, because it works fine under Unix. I have : - this "E:\pearix-dev\pfm15x" directory exists - this "E:\pearix-dev\pfm15xpackage.xml" (file | dir) does not exists - my test script into "E:\pearix-dev\pfm15x" directory Tested under PHP 5.1.4 and PHP 4.4.2 under windows, with Apache 2.0.55 gave WRONG results Tested under PHP 5.1.4 and PHP 4.4.0 under Unix with Apache 2.2.2 gave GOOD (expected) results. Feedback are welcome ! Laurent Laville Reproduce code: --------------- <?php $outputdir = dirname(__FILE__); // "E:\pearix-dev\pfm15x" $packagefile = 'package.xml'; var_dump($outputdir); var_dump($outputdir . $packagefile); if (file_exists($outputdir . $packagefile)) { var_dump('condition 1 passed'); } if (is_writable($outputdir . $packagefile)) { var_dump('condition 2 passed'); } if ((file_exists($outputdir . $packagefile) && is_writable($outputdir . $packagefile))) { var_dump('condition 3 passed'); } ?> Expected result: ---------------- None of "condition x passed" message displayed, but only string(20) "E:\pearix-dev\pfm15x" string(31) "E:\pearix-dev\pfm15xpackage.xml" Actual result: -------------- The 3 conditons are TRUE string(20) "E:\pearix-dev\pfm15x" string(31) "E:\pearix-dev\pfm15xpackage.xml" string(18) "condition 1 passed" string(18) "condition 2 passed" string(18) "condition 3 passed" -- Edit bug report at http://bugs.php.net/?id=37687&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37687&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37687&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37687&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37687&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37687&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37687&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37687&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37687&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37687&r=support Expected behavior: http://bugs.php.net/fix.php?id=37687&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37687&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37687&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37687&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37687&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37687&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37687&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37687&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37687&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37687&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37687&r=mysqlcfg
