ID: 48729 Comment by: kripper3 at hotmail dot com Reported By: kripper at imatronix dot cl Status: Feedback Bug Type: Streams related Operating System: Windows XP SP3 PHP Version: 5.2.10 Assigned To: pajoye New Comment: It works on 5.3 (CVS), only with php.exe. Thanks. Previous Comments: ------------------------------------------------------------------------ [2009-07-03 16:22:21] pajoye@php.net Please try using CLI, not cgi. ------------------------------------------------------------------------ [2009-07-03 16:19:46] kripper3 at hotmail dot com Tested on PHP 5.3 (5.3.1-dev) (CVS), released 2009-Jul-03 17:00:00. proc_open() is still not able to read from stdin on windows, when running PHP from a DOS shell. ------------------------------------------------------------------------ [2009-06-30 07:52:33] pajoye@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2009-06-30 05:16:57] kripper3 at hotmail dot com HINT for reproducing: 1) Download plink.exe (http://the.earth.li/~sgtatham/putty/latest/x86/plink.exe) to C:\ for testing a command which expects stdin. 2) Copy this script to C:\test.php --- <? $espec_descriptor = array( 0 => fopen('php://stdin', 'r'), 1 => fopen('php://stdout', 'w'), 2 => array("file", "C:\\error-output.txt", "a") ); $cmd = "C:\\plink.exe root@hostifex.com"; $process = proc_open($cmd, $espec_descriptor, $pipes); if (is_resource($process)) { echo "The command was supposed to prompt the password (it works on 5.1.2)\n"; proc_close($process); } else { echo "Trivial Error. Please check your setup for reproducing the problem.\n"; } ?> --- 3) Execute in DOS Shell: C:\PHP\php-cgi.exe C:\test.php 4) A prompt reading from stdin is expected (but fails con 5.2.x). It works with: http://museum.php.net/php5/php-5.1.2-Win32.zip 5) Check the C:\error-output.txt if you get other results. 6) (Cleaning) Delete C:\Test.php and C:\error-output.txt. Thanks. ------------------------------------------------------------------------ [2009-06-30 03:35:07] kripper at imatronix dot cl Description: ------------ proc_open() doesn't read from stdin, when running PHP from console. Reproduce code works on PHP 5.1.2. popen works, but seems not to be suited for running interactive shell commands from PHP. Console scripts trying to run interactive commands will fail. Reproduce code: --------------- $espec_descriptor = array( 0 => fopen('php://stdin', 'r'), 1 => fopen('php://stdout', 'w'), 2 => array("file", "C:\\error-output.txt", "a") ); $cmd = "<any command reading from stdin, for example: plink.exe>"; $process = proc_open($cmd, $espec_descriptor, $pipes); if (is_resource($process)) { set_time_limit(0); return proc_close($process); } else { return -1; } Expected result: ---------------- proc_open() should run the command and allow it to read from stdin. Actual result: -------------- Commands fail to read from stdin and close inmediatly. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48729&edit=1
