Question

Client:

<?php

$gmclient= new GearmanClient();
$gmclient->addServer();
$gmclient->doBackground("reverse", "this is a test");

echo "done!\n";

Worker:

<?php

echo "Starting\n";

$gmworker= new GearmanWorker();
$gmworker->addServer();
$gmworker->addFunction("reverse", "reverse_fn");

while($gmworker->work()){}

function reverse_fn($job)
{

  $result= strrev($job->workload());

  $fp = fopen('test.txt', 'a');
  fwrite($fp, $result);
  fclose($fp);
  echo "Result: $result\n";
  return $result;
}

?>

The problem is that when I call the client nothing happens until I run

php worker.php

then it writes to the file, but the shell is just stuck at

[user@server gearman]$ php worker.php 
Starting
Result: tset a si siht

Is there anyway I can make it so that when it calls doBackground, it runs the worker.php file in the background? I also want to make sure this work when gearmand is restarted so that I don’t have to run worker.php if the daemon is restarted.

Take a look at supervisord (supervisord.org) for managing your php scripts. supervisor will do the process management for you, and respawn php scripts in the background if they die
