Question

I have gone though the tutorial of redis and php. i am currently using predis. I have three files named form.php, submit.php, and mail.php. in form.php i have a simple form. in submit.php i have written a simple code for display something. and inmail.php. i have written some code for sending mail. when i submit form in form.php then it should go on submit.php. and mail.php should start in background. I have written some thing like this:

submit.php

      $client = new \Predis\Client();
  $client->select(4);
      $client->lpush('xxxx',$x['to']);
 $arrOutput=shell_exec('php mail.php');
    print_r($arrOutput);

in mail.php

  require '/var/www/predis/autoload.php';
        \Predis\Autoloader::register();

echo "hi";

require_once('Services/Notification.php');

$client = new \Predis\Client();
      $client->select(4);

$u=$client->blpop('xxxx',0);

var_dump($u);

notification_on_signup($u[1]);

then please tell me how should i configure this thing. so that i can send mail.php in bakground

You can achieve what you want very easily. In most modern JS framework you can submit not only an asynchronous call to server, but also a callback function for success/failure.

Assuming you use jQuery it would similar to this one:

$.post('submit.php', function(response) {
    //do you want to do anything with response string?
    //do it now
    $.post('mail.php', function(response) {

    });
});

Check the docs.
