PHP Flush that works… even in Nginx

Question

Is it possible to echo each time the loop is executed? For example:

foreach(range(1,9) as $n){
    echo $n.\"\\n\";
    sleep(1);
}

Instead

Answer 1

You need to flush the php's buffer to the browser

foreach(range(1,9) as $n){
    echo $n."\n";
    flush();
    sleep(1);
}
