Edit report at https://bugs.php.net/bug.php?id=39992&edit=1 ID: 39992 Comment by: crrodriguez at opensuse dot org Reported by: nlopess@php.net Summary: proc_terminate() leaves children of child running Status: No Feedback Type: Bug Package: Program Execution Operating System: linux PHP Version: 6CVS-2006-12-30 (CVS) Block user comment: N Private report: N New Comment: I cannot reproduce this on linux with PHP 8.x git master.. even when run thousands of times through a shell.. Im almost certainly missing something oe it was a bug in the shell... Previous Comments: ------------------------------------------------------------------------ [2021-02-16 13:11:51] nikic@php.net @machitgarha: To clarify, you're still seeing this issue when passing an *array* command to proc_open()? It is expected that this doesn't work when passing a *string* command, because those are invoked through a shell. ------------------------------------------------------------------------ [2021-02-16 12:23:29] machitgarha at outlook dot com The bug is reproducible on 7.4.15, Fedora Workstation 33. Any fixes? ------------------------------------------------------------------------ [2020-03-15 04:22:04] php-bugs at lists dot php dot net No feedback was provided.

Thank you. ------------------------------------------------------------------------ [2020-03-06 10:38:38] nikic@php.net I believe this should be addressed in PHP 7.4 by writing: $proc = proc_open( ['php', '-r', 'while(1){}'], [2 => ['redirect', 1]], $pipes); var_dump(proc_terminate($proc)); This will not go through a shell, and as such the created process will be terminated directly. Please let me know if there are still issues when going through the shell-free interface. ------------------------------------------------------------------------ [2016-03-06 02:29:59] php at mattwhitlock dot name An easy workaround... Instead of: $proc = proc_open('cat', ...); Use this: $proc = proc_open('exec cat', ...); It tells the shell to replace its own process with the command being executed rather than forking a child process. This way you can properly kill the command using proc_terminate($proc). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
