From: antronin at gmail dot com Operating system: Ubuntu 12.10 PHP version: Irrelevant Package: POSIX related Bug Type: Bug Bug description:posix_isatty and posix_ttyname weird var handling Description: ------------ --- From manual page: http://www.php.net/function.posix-isatty --- Although documentation says "Returns TRUE if fd is an open descriptor connected to a terminal and FALSE otherwise." clearly this is not the case.

Test script: --------------- var_dump(posix_isatty(true)); var_dump(posix_isatty(false)); var_dump(posix_isatty('str')); var_dump(posix_isatty(array())); var_dump(posix_isatty(42)); for ($i=0; $i<50; $i++) { var_dump(posix_isatty($i)); } Expected result: ---------------- (bool)false (bool)false (bool)false (bool)false (bool)false (bool)false x50 Actual result: -------------- (bool)true (bool)true (bool)true (bool)true (bool)false (bool)true (bool)true (bool)true (bool)false x47 -- Edit bug report at https://bugs.php.net/bug.php?id=63639&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63639&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63639&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63639&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63639&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63639&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63639&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63639&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63639&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63639&r=support Expected behavior: https://bugs.php.net/fix.php?id=63639&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63639&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63639&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63639&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63639&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63639&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63639&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63639&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63639&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63639&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63639&r=mysqlcfg
