From: mrueegg at metaworx dot ch Operating system: Windows NT 5.1 build 2600 (WiXP) PHP version: 5CVS-2006-06-26 (snap) PHP Bug Type: Filesystem function related Bug description: file_exists() failes on long filenames (gt 259)
Description: ------------ on my windows system the function file_exists() returns true whenever the full qualified file path has more than a total of 259 characters. if the path is relative, the cwd will be prepended and counted (e.g. 260-28=232). i testet it with the snapshot of today (26-Jun-2006 16:19) as well. plain php.exe, no changes to modules or php.ini. same result. i use an immaginary filename in the root of 'C:\'. the file obviously does not exist. refer to http://bugs.php.net/bug.php?id=31347 describing the similar error with strlen > 255. Reproduce code: --------------- <?php echo php_uname(); if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { echo "Running on Windows with PHP ", phpversion(), "\n"; $root = "c:".DIRECTORY_SEPARATOR; } else { die("problem could not be reproduced on linux (debian with PHP 5.1.2-1+b1)\n"); } $max = 260; $t = $root.str_repeat('x', $max - strlen($root)); var_dump(strlen($t)); var_dump(file_exists($t)); $t = $root.str_repeat('x', $max - strlen($root) - 1); var_dump(strlen($t)); var_dump(file_exists($t)); echo "\nif no root is given, then cwd is prepended:\n"; var_dump(getcwd().DIRECTORY_SEPARATOR); var_dump(strlen(getcwd().DIRECTORY_SEPARATOR)); echo "\n"; $t = str_repeat('x', $max - strlen(getcwd().DIRECTORY_SEPARATOR)); var_dump(strlen($t)); var_dump(file_exists($t)); $t = str_repeat('x', $max - strlen(getcwd().DIRECTORY_SEPARATOR) - 1); var_dump(strlen($t)); var_dump(file_exists($t)); Expected result: ---------------- Windows NT MWXDEV 5.1 build 2600 Running on Windows with PHP 5.1.4 int(260) bool(false) int(259) bool(false) if no root is given, then cwd is prepended: string(28) "P:\Programming\xampp\htdocs\" int(28) int(232) bool(false) int(231) bool(false) an exception/warning would also be acceptable. but in case of doubt the function should return false. Actual result: -------------- Windows NT MWXDEV 5.1 build 2600 Running on Windows with PHP 5.1.4 int(260) bool(true) int(259) bool(false) if no root is given, then cwd is prepended: string(28) "P:\Programming\xampp\htdocs\" int(28) int(232) bool(true) int(231) bool(false) -- Edit bug report at http://bugs.php.net/?id=37918&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37918&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37918&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37918&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37918&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37918&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37918&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37918&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37918&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37918&r=support Expected behavior: http://bugs.php.net/fix.php?id=37918&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37918&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37918&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37918&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37918&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37918&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37918&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37918&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37918&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37918&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37918&r=mysqlcfg
