Edit report at https://bugs.php.net/bug.php?id=63639&edit=1 ID: 63639 Updated by: mike@php.net Reported by: antronin at gmail dot com Summary: posix_isatty and posix_ttyname weird var handling -Status: Open +Status: Not a bug Type: Bug Package: POSIX related Operating System: Ubuntu 12.10 PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Expecting integer parameters the arguments get converted, so: true -> 1 -> STDOUT false/'str'/array() -> 0 -> STDIN Previous Comments: ------------------------------------------------------------------------ [2012-11-28 21:55:52] antronin at gmail dot com 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. It also returns TRUE if the parameter is not a file descriptor at all except is it is an integer < 3. 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 this bug report at https://bugs.php.net/bug.php?id=63639&edit=1
