Call to undefined function pcntl_fork()

how I fix this problems. I used XAMPP for windows 7.
Problems are

$pid = pcntl_fork();

  if ($pid == -1) {
die("ERROR");
  }
  else if ($pid == 0) {
        head($argv[2]);
     exit(0);
  }
  else {
$pids[] = $pid;
      }
    }

Thanks

What I have tried:

else if ($pid == 0) {
        head($argv[2]);

if ($pid == 0)
head($argv[1]);
     exit(0);

Solution 1

Unfortunately, the pcntl installation page[^] says:

Quote:
Currently, this module will not function on non-Unix platforms (Windows).

This solutions are running windows executable files inside php files, any suggestion

The point would be that you simulate a fork by running the same process as the currently running one. But I don't really have experience with it myself.

Kepiting Bula 5-Jun-19 5:01am

I see, U say this isn't work with windows os and running process is one or same process but the list of code is not same

Thomas Daniels 5-Jun-19 5:02am

Yeah, the concept of "forking" doesn't actually exist on Windows.

any suggest,

Not anymore, I gave you a link which could help finding the closest possible alternative, I found no other resources.

I also don't know what your code wants to do, perhaps there's an alternative to forking and you don't need forking at all. But I can't say anything about that if I don't know your use case.

my use case

$pid = pcntl_fork();

  if ($pid == -1) {
die("ERROR");
  }
  else if ($pid == 0) {
        head($argv[2]);
     exit(0);
  }
  else {
$pids[] = $pid;
      }
    }

foreach ($pids as $pid) {
  pcntl_waitpid($pid, $status);
}

}

I trying to changes:

else if ($pid == 0) {
        head($argv[2]);

if ($pid == 0)
head($argv[1]);
     exit(0);

I don't think I know enough about pcntl_fork to know what exactly that script does, let alone to suggest an alternative... so sorry, I don't think I can help you further.
