how to output php result in real time in browser?

Question

I've created this code and it shows next integer every second but there are also errors along with the output.

<?php

ob_implicit_flush();
for ($i = 0; $i < 30; $i++) {
  echo "-> $i <br>\n";
  ob_end_flush();
  ob_end_clean();
  sleep(1);
}

?>

error:

Notice: ob_end_flush(): failed to delete and flush buffer. No buffer to delete or flush in c:\apache\www\TEST.PHP on line 6
Notice: ob_end_clean(): failed to delete buffer. No buffer to delete in C:\apache\www\TEST.PHP on line 7
-> 4

Putting @ sign on the ob_* functions to silence these errors also disables realtime output.

You are ending ob_end_flush();

You should use only this:

ob_flush();

with ob_flush(); it also doesn't work, output is buffered as usual.
