PHP pcntl Multi-process learning

Go: PHP pcntl multi-process learning

1, capture the child process exit (listen SIGCHLD signal, and then call the Pcntl_wait function)

DECLARE (Ticks=1);p cntl_signal (SIGCHLD, "Sig_handler"), function Sig_handler ($signo) {    switch ($signo) {        case SIGCHLD:            $status = 0;            $child _id = pcntl_wait ($status);            echo sprintf ("Child exit ID: {$child _id} \ n");            Exit (0);            break;        Default:            echo ' uncaugh signal! ';    }} $pid = Pcntl_fork (), if ($pid >0) {    echo sprintf ("fork Child ID: {$pid} \ n");        while (1) {        sleep (1);    }} else{    echo "Child exit \ n";}

2. Capture child process exit (call pcntl_wai* function directly)

3. Capture sub-process exit (pipeline readable between IO multiplexing monitoring processes)
