I have the following code

<?php
  if(isset($_POST['submit'])){
    exec('java -jar "C:\Temp\showinfo_v2.jar"', $response);
    print '<br>';
   }
?>

This piece of code shows me my personal information but i have to wait like 30 seconds for it to show. I need way that it simultaneously shows me info step by step instead of giving me my whole output in 30 seconds

What I have tried so far

I tried changing the exec() to system() and turn output_buffering off in php.ini
Changed exec() command to shell_exec() and also some other codes but none worked.

PHP buffers the output, this means you cannot preview it live directly in the browser like you would in a console. – Noah Boegli Mar 10 '20 at 08:24
Is there anything you would recommend? – phpscrub Mar 10 '20 at 08:27

Does this answer your question? [PHP reading shell\_exec live output](https://stackoverflow.com/questions/20107147/php-reading-shell-exec-live-output) – Nico Haase Mar 10 '20 at 08:28
I would recommend the solution to the question mentioned by @NicoHaase above haha, he was faster than me. – Noah Boegli Mar 10 '20 at 08:29
But in that thread, he used cmd which im not familiar with? – phpscrub Mar 10 '20 at 08:35
Did not work :( – phpscrub Mar 10 '20 at 08:59
By replacing `$proc = popen($cmd, 'r');` with `$proc = popen('java -jar "C:\Temp\showinfo_v2.jar"', 'r');` does it work? – Noah Boegli Mar 10 '20 at 09:16
