Hi Jochen,
I had grief with background processes in Windows a while back, the
solution was to use popen() to call the 'start /B' command.
Code is like:
function background_exec($command)
{
if(strtoupper(substr(PHP_OS, 0, 3)) == 'WIN')
{
pclose(popen('start /B ' . $command, "r"));
}
else
{
$command = $command . ' > /dev/null 2>&1 &';
exec($command);
}
}
This allows any command in $command to run as a background process. This
means PHP does NOT wait for execution.
I don't know if this helps at all. I was doing image conversion also,
and due to the large size of the images background processing was desirable.
Cheers,
Stig
