Bug #69339 [NEW]: realpath(false) returns CWD

From: sebastian Operating system: Linux PHP version: 5.6.7 Package: Filesystem function related Bug Type: Bug Bug description:realpath(false) returns CWD Description: ------------ realpath(false) returns the CWD. This is the behavior that the manual describes for blank or NULL values: "Whilst a path must be supplied, the value can be blank or NULL In these cases, the value is interpreted as the current directory." Either this is a bug in PHP or the documented needs to be amended. Test script: --------------- <?php var_dump(realpath(false)); var_dump(realpath(true)); var_dump(realpath(0)); var_dump(realpath(null)); var_dump(realpath('')); Expected result: ---------------- bool(false) bool(false) bool(false) string(8) "/home/sb" string(8) "/home/sb" Actual result: -------------- string(8) "/home/sb" bool(false) bool(false) string(8) "/home/sb" string(8) "/home/sb" -- Edit bug report at https://bugs.php.net/bug.php?id=69339&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69339&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69339&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69339&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69339&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69339&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69339&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69339&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69339&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69339&r=support Expected behavior: https://bugs.php.net/fix.php?id=69339&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69339&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69339&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69339&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69339&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69339&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69339&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69339&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69339&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69339&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69339&r=mysqlcfg
