I am trying to start a cd rip with cdparanoia -E 1
and want to process the progress bar.
The sample code does output content in browser but just after everything is finished. If its called in cli content is displayed directly.
$cmd = 'cdparanoia -e 1';
@ob_end_clean();
$proc = popen($cmd, 'r');
while (!feof($proc))
{
echo fread($proc, 4096).'<br>';
flush();
@ob_flush();
}
My env is debian with nginx 1.6.2 and php5-fpm 5.6.17.
