From: gilad dot buzi at concatel dot com Operating system: Windows (2000/XP) PHP version: 5.0.3 PHP Bug Type: *Directory/Filesystem functions Bug description: is_dir and is_file (incorrectly) return true for any string > 255 characters
Description: ------------ is_dir() and is_file() (incorrectly) return true for any string larger than 255 characters. I tried this on two different machines, with the out of the box, precompiled/downloaded Windows version of php 5.0.3. No changes were made to the standard php.ini-dist. No extra extensions were loaded. We are using PHP as an Apache2 module (php2apache2.dll). We also tried the latest CVS snapshot (5CVS-2004-12-30 (dev)) and got the same results. We tried, and could NOT reproduce this on Linux. It only failed on windows platforms. Curiously (or maybe not so curious), file_exists() DOES work fine. Reproduce code: --------------- <? $myfilename="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccsssssssssssssssssssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccssssssssssssssssssssssssssssssssssssssssssssss"; echo "myfilename is: $myfilename"; echo "<br>myfilename is ".strlen($myfilename)." characters long"; echo "<br>is_dir: ".is_dir($myfilename); echo "<br>file_exists: ".file_exists($myfilename); echo "<br>is_file: ".is_file($myfilename); $myfilename="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccsssssssssssssssssssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccssssssssssssssssssssssssssssssssssssssssssssss"; echo "<br><br>myfilename is: $myfilename"; echo "<br>myfilename is ".strlen($myfilename)." characters long"; echo "<br>is_dir: ".is_dir($myfilename); echo "<br>file_exists: ".file_exists($myfilename); echo "<br>is_file: ".is_file($myfilename); ?> Expected result: ---------------- is_dir() and is_file() should return false if the file or directory does not exist, regardless of the length of the string they are passed. Actual result: -------------- Result for above script is: myfilename is: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccsssssssssssssssssssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccssssssssssssssssssssssssssssssssssssssssssssss myfilename is 255 characters long is_dir: file_exists: is_file: myfilename is: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccsssssssssssssssssssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaccccccccccccccccccccccccccssssssssssssssssssssssssssssssssssssssssssssss myfilename is 256 characters long is_dir: 1 file_exists: 1 is_file: -- Edit bug report at http://bugs.php.net/?id=31347&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31347&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31347&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31347&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31347&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31347&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31347&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31347&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31347&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31347&r=support Expected behavior: http://bugs.php.net/fix.php?id=31347&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31347&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31347&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31347&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31347&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31347&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31347&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31347&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31347&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31347&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31347&r=mysqlcfg
