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

<?php
    header('Content-Type: text/html; charset=utf-8');

    // I think maybe you can set output_buffering using ini_set here, but I'm not sure.
    // It didn't work for me the first time at least, but now it does sometimes...
    // So I set output_buffering to Off in my php.ini,
    // which normally, on Linux, you can find at the following location: /etc/php5/apache2/php.ini

    @ini_set('output_buffering','Off');
    @ini_set('zlib.output_compression',0);
    @ini_set('implicit_flush',1);
    @ob_end_clean();
    set_time_limit(0);
    ob_start();

    //echo str_repeat('        ',1024*8); //<-- For some reason it now even works without this, in Firefox at least?

    flush();

    //Note: ob_flush comes first, then you call flush. I did this wrong in one of my own scripts previously.
    for($i=0; $i<5; $i++) {
        echo $i.'<br>';
        ob_flush();
        flush();   
        sleep(1);
    }
