Help with PHP Process Control Functions

[Colin Davis]

Hi,

I have written a script that basically sends an email (using sockets). I
want this script to be able to run multiple copies of itself so that it
doesn't have to wait for one mail sending to finish before starting on the
next. I understand that I need to use the PHP pcntl_ family of functions to
control the processes, but am not sure where to start. There aren't many
helpful articles on the internet about this topic! Any example code or help
would be greatly appreciated.

Thanks,
Colin.

This sample has had a lot of code removed, but it may help
understanding how this works: PHP must be compiled with pcntl.

$pid = pcntl_fork();
if ($pid)
{
// we are the parent
sleep(1);
$pid1 = pcntl_fork();
if ($pid1)
{
sleep(1);
$pid2 = pcntl_fork();
if($pid2)
{
sleep(1);
$pid3 = pcntl_fork();
if($pid3)
{
sleep(1);
}
else
{
// we are in child
sleep(1);
# Do something here
}
}
else
{
// we are in child
sleep(1);
# Do something here
}
}
else
{
// we are in child
sleep(1);
# Do something here
}

}
else
{
// we are the child
sleep(1);
# Do something here
}
