Hi,
I was the same problem. No one of these below has effect. Like my
English :-).
exec('cmd /C "ping 147.32.x.x -t"');
exec('cmd /C "start ping 147.32.x.x -t"');
exec('cmd /C "pingIP.bat"');
exec('cmd /C "start pingIP.bat"');
content of pingIP.bat
ping 147.32.x.x -t or cmd /c 147.32.x.x -t or cmd /c 147.32.x.x -t
so
<?php
$fp=popen("start InstallLinux.exe","r");
pclose($fp);
echo "Hastalavista Gates";
?>
Why "r" and not "w"? I dont know. "r" was in the manual. I think, it is
much of a muchness.
wella

So the right question may be: How do i redirect the standardoutput
under
Windows, so that PHP does NOT wait for the end of the Programm.
I tried some more lines:
exec( "cmd.exe /c start c:/windows/notepad.exe <nul: 2>nul: >nul:"
);
exec( "c:/windows/notepad.exe <nul: 2>nul: >nul:" );
It's always the same: PHP always wait's for notepad's end. BUT I DON'T
WANT TO WAIT!
What do i have to do (under windows) to not wait for the end of the
program ???

It seems to be so, that PHP wait's for the last process of the group of
child processes to terminate.
Is there any way (in PHP) to break that behavour?

you have to make sure that the
output of that program is redirected to a file or some other output
stream or else PHP will hang until the execution of the program ends."

I don't see any bugs here. It's pretty well expected behaviour.
The docs say: "If you start a program using this function and want to
leave it running in the background, you have to make sure that the
output of that program is redirected to a file or some other output
stream or else PHP will hang until the execution of the program ends."
But your program *waits for your input* (i.e. until you close it), so
PHP will wait for it too, 'cause exec() "returns the last line from the
result of the command" (c).
