Please re-read the instructions at http://bugs.php.net/how-to-report.php If you can provide more information, feel free to add it to this bug and change the status back to "Open". Thank you for your interest in PHP. signal_pro won't fire if you kill the parent, and when you kill the child posix_getpid will return the PID of the current process (which is the parent). What do you think it should do? ------------------------------------------------------------------------ [2017-06-01 09:34:55] shan dot liu at msn dot com Description: ------------ // <?php if(pcntl_fork())die(); $fp = pcntl_fork(); if (!$fp) { //child sleep(300); exit; } //parent function signal_pro($signo){ echo posix_getpid(); }; pcntl_signal(SIGTERM,'signal_pro'); declare(ticks = 1){ while (true){ $pid=pcntl_wait($status); if($pid==-1)break; } } ?> //linux shell kill parent id,not output kill child id,is output:parent id signal listen is wong???
