From: tokul at users dot sourceforge dot net Operating system: PHP version: 5.1.4 PHP Bug Type: Filesystem function related Bug description: invalid return of file_exists() in safe mode
Description: ------------ PHP documentation (http://www.php.net/file-exists) states that file_exists() function returns false, when file is inaccessible due to safe mode restrictions. Tested PHP 4.3.10, 4.4CVS (200607021030), 5.1.4 and 5.2CVS(200607021030). In PHP 5.1.4 and 5.2CVS file_exists() function returns true, when file exists, but is inaccessible due to safe mode restrictions. Other php versions work as documented. Reproduce code: --------------- <?php var_dump(ini_get('safe_mode')); var_dump(file_exists('/usr/games/fortune')); var_dump(is_file('/usr/games/fortune')); var_dump(is_dir('/usr/games/fortune')); ?> Expected result: ---------------- When safe_mode is on ---- string(1) "1" bool(false) bool(false) bool(false) ---- When safe_mode is off ---- string(0) "" bool(true) bool(true) bool(false) ---- Actual result: -------------- When safe_mode is on ---- string(1) "1" bool(true) bool(false) bool(false) ---- When safe_mode is off ---- string(0) "" bool(true) bool(true) bool(false) ---- -- Edit bug report at http://bugs.php.net/?id=37987&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37987&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37987&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37987&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37987&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37987&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37987&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37987&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37987&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37987&r=support Expected behavior: http://bugs.php.net/fix.php?id=37987&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37987&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37987&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37987&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37987&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37987&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37987&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37987&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37987&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37987&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37987&r=mysqlcfg
