note 107220 modified in function.pcntl-exec by danbrown

I spent a lot of time trying to figure this powerful option out so I didn't get error 2 or error 8. The documentation says it can execute a binary file and here is a good example that works that I found;

<?php
 print "Before\\n";
 pcntl_exec("/usr/bin/uptime");
 print "After\\n";
?>

However I wanted it to run another php program and after wasting a lot of time I finally got it.

<?php
$tasks2=array('/var/www/example.php');
pcntl_exec("/usr/bin/php",$tasks2);
?>

The php script has to be in an array and you execute the binary php file

I'll be adding this to launching a child and run it seperately using this function

<?php
function launchchild($programexe,$programvars)
{
//foreach ($tasks as $key => $v){
 switch ($pid = pcntl_fork()) {
 case -1:
 // @fail
 die('Fork failed');
 break;

 case 0:
 // @child: Include() misbehaving code here
 print "FORK: Child #{$x} \\n";
		 echo "child after fork:", getmypid(), PHP_EOL;
		 pcntl_exec($programexe,$programvars);
 // generate_fatal_error(); // Undefined function
 break;

 default:
 // @parent
 print "FORK: $x Parent\\n";
		 echo "parent after fork:", getmypid(), PHP_EOL;
 // pcntl_waitpid($pid, $status);
 break;
 }

print "Done! :^)\\n\\n";
}
