Rebel7284 Posted October 21, 2008 Share Posted October 21, 2008 Hi, I have a problem with signal handling not working in cli PHP Relevant information: PHP 4.3.11 (cli) (built: Jun 21 2005 12:10:12) Cent OS kernel 2.6.9 Sample code: <? //declare(ticks = 1); pcntl_signal(SIGINT, "sighandler"); pcntl_signal(SIGQUIT, "sighandler"); function sighandler($signo){ echo "Got ", $signo; //ob_end_flush(); } while(1){ sleep(5); } ?> With this code running, I can press Ctrl-C and Ctrl-\ as much as I want, it ignores it and just sits there. If I uncomment the ticks line, the signals are simply not handled and result in immediate script termination. Does anyone have any idea what I'm doing wrong?

trq Posted October 21, 2008 Share Posted October 21, 2008 Is the process control extension installed? Is error reporting enabled? Any errors? Link to comment https://forums.phpfreaks.com/topic/129397-problem-with-signals/#findComment-670831 Share on other sites More sharing options...
Rebel7284 Posted October 21, 2008 Author Share Posted October 21, 2008 Is the process control extension installed? Huh? Since when is it an extension? I was under impression that it was a core part of PHP. Where in php.ini would i find this out? Is error reporting enabled? Any errors? Warnings and higher are enabled. No errors are being displayed.

trq Posted October 21, 2008 Share Posted October 21, 2008 Huh? Since when is it an extension? Read here. Where in php.ini would i find this out? There is no runtime configuration. Id check with phpinfo(); Link to comment https://forums.phpfreaks.com/topic/129397-problem-with-signals/#findComment-670842 Share on other sites More sharing options...
Rebel7284 Posted October 21, 2008 Author Share Posted October 21, 2008 but pcntl_fork works. If it was a problem with the extension, that wouldn't work either, right? Edit: just looked in phpinfo, --enable-pcntl is there. Link to comment https://forums.phpfreaks.com/topic/129397-problem-with-signals/#findComment-670845 Share on other sites More sharing options...

trq Posted October 21, 2008 Share Posted October 21, 2008 I'm at home now and have tested your script. Works as expected from here. Hitting Ctrl-C then Ctrl-\ produces....

DarkWater Posted October 21, 2008 Share Posted October 21, 2008 I really want to say that your really old PHP version has something to do with it, but I can't be sure.

Rebel7284 Posted October 22, 2008 Author Share Posted October 22, 2008 One more bump just in case anyone else has any idea on what I can try to do to figure out the root of this problem.
