PHP output buffering issues

Question

since two days i'm trying to stop the buffer on my server, i disabled the output_buffering in php.ini i checked it was disabled with phpinfo().

Under xampp(Localhost) it works like a charm, same testing code(below), the code runs without waiting for everything to be finished, no buffer, a dream =)

On my server the output_buffering show me No value in phpinfo() so i think it's disabled, but still it's not workingn i need to wait until the loop finish his work, anyway to make this work like on my xampp config ? thanks !

testing code here :

for($i=1; $i<=5000; $i++){
    echo $i."<br>";

    flush();
    usleep(1000);
}

ps : i tested with php 5.6 & php7 on Debian and Ubuntu, my xampp is naturally running on windows(10)

if you want this kind of browser interaction you should use client side code — , Nov 22 '16 at 20:06

You need to use ob_flush() and flush()

What's the difference you may ask? That's a good question.

Modern browsers don't display anything until the body of the response contains a certain amount of data (about 1024 bytes). The following may look a bit hacky - but like this it works as expected:

<?php
echo '<!-- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -->';
flush();
for($i=1; $i<=5000; $i++) {
  echo $i."<br>";
  flush();
  usleep(1000);
}
?>

thanks, it still wont work :( i can't figure why, working like a charm on xampp — user2690397, Nov 23 '16 at 00:10
