#47511 [NEW]: undocumented: is_dir() returns true for symbolic links to directories

From: moquist at majen dot net Operating system: linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: undocumented: is_dir() returns true for symbolic links to directories Description: ------------ If is_dir() wants to return true for symbolic links to directories that's fine, but this should be mentioned in the documentation. Cheers! --matt Reproduce code: --------------- <?php symlink('/etc/', '/tmp/imalink'); if (is_dir('/tmp/imalink')) { print "Hmm. I think /tmp/imalink is a directory! The usually excellent documentation at php.net didn't help me expect this result. :("; } else { print "I think /tmp/imalink is not a directory, which is what I would expect to be the case since I know it's a symlink."; } ?> Expected result: ---------------- I think /tmp/imalink is not a directory, which is what I would expect to be the case since I know it's a symlink. Actual result: -------------- Hmm. I think /tmp/imalink is a directory! The usually excellent documentation at php.net didn't help me expect this result. :( -- Edit bug report at http://bugs.php.net/?id=47511&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47511&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47511&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47511&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47511&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47511&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47511&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47511&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47511&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47511&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47511&r=support Expected behavior: http://bugs.php.net/fix.php?id=47511&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47511&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47511&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47511&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47511&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47511&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47511&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47511&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47511&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47511&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47511&r=mysqlcfg
