Hi all :) I'm creating an excel with PhpSpreadsheet (no prob with that ). I'm working with MVC pattern so flow is :
1) User press download button and call function in controller
2) function in controller call a function in an helpers to create the excel
Now it's a very very long task and i'd like to show the progress of this long task (like a download bar). I've tried with all things that i know (ajax polling , iframe, sse, session variable, static variable) but none seems to work. Could you help me ?
