Description:
------------
The documentation for ob_implicit_flush says that

"Turning implicit flushing on will disable output buffering, the output buffers current output will be sent as if ob_end_flush() had been called."

This is not the case.

If this is indeed the correct behavior, please update the documentation to reflect that and add an example such as the following:

    ob_implicit_flush(true);
    while (@ob_end_flush());


Reproduce code:
---------------
    ob_start();
    ob_implicit_flush(true);
    var_dump(ob_end_flush());


Expected result:
----------------
bool(false)

Actual result:
--------------
bool(true)

Same thing:

php5.1-200602151530$ sapi/cgi/php -q
<?
    ob_start();
    ob_implicit_flush(true);
    var_dump(ob_end_flush());
?>
bool(true)

Another test:

php5.1-200602151530$ sapi/cgi/php -q
<?
    ob_start();
    echo "hello\n";
    ob_implicit_flush(true);
    echo "bye\n";
    ob_end_clean();
?>
(no output)

The ob_implicit_flush() function is not disabling output buffering or sending the current output as the documentation says it should.

This is a documentation problem.

Unlike the manual says, ob_implicit_flush() does neither end output buffering, nor does it flush the current output buffer.

It just causes a flush() when something actually gets written to the webserver.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
