continue php script after connection close


continue php script after connection close  using -'php,codeigniter,output-buffering'

I am trying to continue a PHP Script after the page/connection is closed.

Users will POLL the script in every 1 hour, I want to return some json output and want to continue the script in the background. I am using a shared host and I cannot use cron job.

Here is what I've tried.

ob_start();

ignore_user_abort();

echo "JSON_OUTPUT GOES HERE";

$ob_length = ob_get_length();

header("Content-Type : text/plain",TRUE);
header("Content-Length : $ob_length",TRUE);
header("Connection : Close",TRUE);

flush();
ob_flush();
ob_end_flush();

sleep(3);

echo "You cant see me..";

exit();


I am using Codeigniter framework, But its not working on my live server. It waits 3 seconds and then outputting You cant see me.. too.

Please help me.

Note

Project is hosted in LINUX/WINDOWS/WAMP-SERVER shared hosts.
