Sometimes you need to run several copies of one script at the same time. The easiest method is to do something like this:

for($i=0;$i<10;$i++)
{
system (”/usr/local/bin/php go.php $i > start.log &”);
echo “thread $i started”;
}
?>

Not very elegant, but it works, if you are allowed to use PHP’s system() function. I will tell you how to use pcntl function [...]
