php flush not working

<?php
for($i=0;$i<20;$i++)
{
    echo 'printing...<br />';
    ob_flush();
    flush();

    usleep(300000);
}

?>

Url that contains the code: http://domainsoutlook.com/sandbox/delayed.php

I have a dedicated server so I can make the changes. I am running apache and nginx as the proxy server.

Solution

  • You're using ob_flush without ob_start, so there is nothing to flush for it.

    It also depends on the webserver and proxy and its settings.

    You should disable buffering for Nginx (add proxy_buffering off; to the config file and restart Nginx)

    Also, check if your php.ini contains output_buffering = Off and zlib.output_compression = Off.
