There is no ob_immediate_flush function or like.
Use ob_implicit_flush()

Given a perl script test.pl:
#!/usr/bin/perl
$| = 1; # immediate flush
for ($i=0;$i<10;$i++) {
print "*";
sleep(2);
}
exit;
And a php script test.php:
<?
header("Content-Type: text/plain");
ob_immediate_flush; # here or in php.ini
echo "calling test.pl\n";
passthru("/path/to/test.pl");
echo "finished\n";
?>
Eventhough both scripts have buffering disabled, no progressive content loading
happens. PHP autoflushes the first echo-line, but passthru-output is not flushed until
the test.pl script has completed.
There are situations where this behavior is no good. I have perl-scripts doing jobs on
our server. These perl-scripts are called from a webpage (aka php-script). However, an
inbetween firewall shuts down communication after 5 mins with no data transferred. In
order to keep the connection alive, I rewrote the perl-scripts such as to send a
progress character to the browser every 30 seconds. Not being autoflushed, they don't
keep alive anything :-)
