Hi Tony,
it doenst work.
STDIN is not defined/open. When i understood the manual correctly, its
only defined when using cli sapi.
I have
php -v
PHP 5.0.2 (cgi) (built: Oct 23 2004 14:07:24)
I tired a lot of things, to kill the stream and getting
disconnected...but nothing helped yet.
When i remember me right, we didnt have that prob @ 4.3.x. but not sure
tho.
I have no clue anymore :)

fclose(STDIN); after successful fork() call should help you.

Description:
------------
After forking a process and setting the child as sessionleader (becomes
deamon) you cant disconnect from the current terminal-session (exit)
solong the child is in process.
After typing exit, the terminal prints the output from the child again.
Youre always connected but no more control
Current Config:

Reproduce code:
---------------
#!/usr/local/bin/php -q
<?PHP
declare (ticks = 1);
set_time_limit (0);
ob_implicit_flush ();
error_reporting(E_ALL);
if( ($pid = pcntl_fork()) == -1 ) {
echo "Error: Cant fork myself ! Dying.... \n";
}
elseif($pid) {
//PARENT PROCESS
echo "Parent-Pid: ".getmypid()." quits here\n";
exit(0);
} else {
//CHILD PROCESS
// detatch from the controlling terminal
if (!posix_setsid()) {
die("could not detach from terminal");
}
//Install Signalhandler
pcntl_signal(SIGTERM, "sig_handler");
pcntl_signal(SIGCHLD, SIG_IGN);
$i=0;
$childpid = getmypid();
//Do something for testing
while ($i<20){
sleep(1);
echo "Child-Pid $childpid ist working -> type exit to quit your
shell-session ->it doesnt close the connex \n";
$i++;
}
echo "Just now we get diconnectet from the shell\n";
exit(0);
}
function sig_handler($signo) {
switch($signo) {
case SIGTERM:
exit;
case SIGCHLD:
while( pcntl_waitpid(-1,$status,WNOHANG)>0 ) { }
break;
default:
break;
}
}
Expected result:
----------------
closing shell (telnet/ssh) and the child doing his background work
Actual result:
--------------
when starting ./testd.php (above) it looks
7360 simon 15 0 7308 2060 6856 S 0.0 0.2 0:00.00 sshd
7361 simon 25 0 4396 1340 3948 S 0.0 0.1 0:00.00 bash
7976 simon 16 0 10012 3452 8872 S 0.0 0.3 0:00.00 testd.php
when "EXIT" the shell
7360 simon 15 0 7308 2060 6856 S 0.0 0.2 0:00.00 sshd <---
left
solong the child repeats 20 times
7360 simon 15 0 7308 2060 6856 S 0.0 0.2 0:00.00 sshd
when the child is done
everthing got closed and the terminal is disconnected
