Server sent events work, but with a massive time delay

Question

Ill start off by saying this works perfectly on my local machine, the js example below connects to stream.php and receives a continuous update of the servers current time every

Answer 1

Server.php needs to be as follows:

stream.php

while(true)
{
    // Headers must be processed line by line.
    header('Content-Type: text/event-stream');
    header('Cache-Control: no-cache');

    // Set data line
    print "Event: server-time" . PHP_EOL;
    print "data: " . date( 'G:H:s', time() ) . PHP_EOL;
    print PHP_EOL;

    ob_end_flush();     // Strange behaviour, will not work
    flush();            // Unless both are called !

    // Wait one second.
    sleep(1);
}
