Ok, then this is an error in the documentation.
The quoted paragraph should get removed alltogether, as it is plain
wrong.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

To avoid this problem use php-cli.ini with settings specific to CLI.

------------------------------------------------------------------------

[2003-08-28 15:49:48] eru@[...].net

Description:
------------
From http://de.php.net/manual/en/features.commandline.php:

"It is desired that any output coming from print(), echo() and friends
is immediately written to the output and not cached in any buffer. You
still can use output buffering  if you want to defer or manipulate
standard output."

Right, that's exactly what you expect, when using CLI, but this only
works as long, as you don't have a php.ini, where output_buffering is
enabled. The unfortunate thing is only, you can't change it in your
script, because it's not PHP_INI_USER. The only way out, is either
creating a php.ini for CLI only, which hardly every installation has,
by declaring -n in your commandline, which isn't desirable either, when
you rely on certain settings in php.ini or by passing a -d
output_buffering=0 on the commandline, but I wasn't able to achieve
this in a #!/usr/local/bin/php line at the top of the script.

So, what we have here in my opinion is a contradictory situation,
because implicit_flush = 1 is overruled by outbut_buffering = 4096.


Reproduce code:
---------------
<?php
var_dump(ini_get("implicit_flush"));
sleep(2);
?> 



Expected result:
----------------
string(1) "1"
<2 seconds of waiting> 

Actual result:
--------------
<2 seconds of waiting> 

string(1) "1"



------------------------------------------------------------------------
