PHP Flush/ob_flush not working

Question

I\'ve tried several attempts at getting my flush and ob_flush to work. I\'ve tried setting the ini to allow buffering, I\'ve tried using several different functions I found

Answer 1

this works now (at least on php 5.5)

ob_end_flush();
while(stuff){
  ..stuff...
  echo('yo');
  flush();
}

no need to sleep or anything else
