well... playing with fork() in a phpcli script, i got some troubles with
childs... anybody knows how to dont get zombies/defuncts with SIGCHLD and
SIGCLD ignoring ? dont worked for me =/
the script is large, so the main pieces of it..
i dont want to know how many childs are running, or if they terminated or
not... i want only to make childs :D
ignoring SIGCHLD in perl works finely... is there anything about the
"phped-layer" to syscalls access ? duh..

<?
declare (ticks = 1);
//original sighangler, not used anymore... i know :)
function sig_handler($signo)
{
out("[+] SIG: $signo\n");
$pid = pcntl_waitpid(-1, &$status, WNOHANG);
if ($signo == SIGCHLD)
out("[+] SIGCHLD PID:$pid\n");
if ($signo == SIGCLD)
out("[+] SIGCLD PID: $pid\n");
//posix_kill($pid, SIGTERM);
}
pcntl_signal(SIGCLD, SIG_IGN);
pcntl_signal(SIGCHLD, SIG_IGN);
$n = 0;
while (1)
{
$n++;
$pid = pcntl_fork();
if ($pid == -1)
{
out("[+] error in fork.\n");
exit(-1);
}
if ($pid == 0)
{
// child...
$pid = posix_getpid();
out("[+] im the number $n !!!\n");
// do some job...
exit(0);
}
else
{
// im parent...
if (($n % 100) == 0)
{
out("[+] giving some time for childs...\n");
sleep(10);
$n = 0;
out("[+] making more childs ;D\n");
}
}
}
