Flush output data

Good guys

The problem is that I can not make the information of a sequence of processes within a function, feed back to the user.

PHP Code:

echo "Data 1 Done";
flush();
ob_flush();
sleep(1);

echo "Data 2 Done";
flush();
ob_flush();
sleep(1);

echo "Data 3 Done";
flush();
ob_flush();
sleep(1); 


Some idea of how to do this, either to use with ajax or simply to show the sequence in the view. Thank you
