Hi I want to create system to send email. I know if i run script and php file have ignore_user_abort() function it will work even user close window. It is ok. But i want to create additional function to show up how many % it have done. I decide to use ajax and update it every 5 seconds. But problem i did not know how i can get result from file. I think to create txt file and every 10 second write result there but i think it will use a lot of memory of server. What you can recommend me?
