This is a documtation problem.
Under certain condition you may infact be able to output data to the
browser from inside the register_shutdown_function handler.

Verified, its supposed to:
The registered shutdown functions are called after the request has
been completed (including sending any output buffers), so it is not
possible to send output to the browser using echo() or print(), or
retrieve the contents of any output buffers using ob_get_contents().
The documentation is correct.

Is this a documentation problem or a php-bug?
According to some users the documented behaviour worked under PHP <
4.1.0, but now the function behaves differently.
Could someone please check this?

I to have run across this problem. I was hoping to use a registered
shutdown function to do some final fairly slow socket processing that
the client didn't need to see. My test case is as follows:
register_shutdown_function('sd');
function sd()
{
echo "I shouldn't be seen";
sleep(5);
}
Causes the browser to echo text then sleep for 5 seconds before
completing the page. I also agree that the manual is incorrect. Is
there another way to force php to close the output stream so slower non
user related functions can be executed?

My problem is that the connection to the browser is still open while
the registered shutdown functions are executing. The documentation
says that from the registered shutdown functions you WON'T be able to
echo or print or modify the contents of the buffer. I can...
Example:
using apache 1.3.27
php version 4.2.3
//////////////////////////////////////////////
<?
function doThing(){
for($i=0;$i<100000;$i++){
//just looping to demonstrate that the page hangs while
executing this function
}
echo "PHP documentation says I shouldn't see this in my browser";
}
register_shutdown_function('doThing');
?>
<html>
Test Page.
<br><br>
</html>
////////////////////////////////////////////
I was hoping to register shutdown functions to do some cleanup -
without affecting the load time of the site. Apparently these
functions don't work that way?
