Its been easy to fork process with pcntl_fork.. but how can we control or process further once all child processes gets completed.. here is the way we can do that...
<?php
for ($i = 1; $i <= 5; ++$i) {
$pid = pcntl_fork();
if (!$pid) {
sleep(1);
print "In child $i\n";
exit($i);
}
}
while (pcntl_waitpid(0, $status) != -1) {
$status = pcntl_wexitstatus($status);
echo "Child $status completed\n";
}
?>
