Hi,
I've tested your code on PHP 4.3.3 and I have the same behavior has yours.
"Hello" is output at the end of the PhpInfo data, followed by a PHP notice :
Notice: ob_end_clean(): failed to delete buffer. No buffer to delete. in
....
And there is an empty "logfile" file created in the Apache directory insteaf
of the script's directory.
If you change in your script:
***********
register_shutdown_function("hello");
echo ("HELLO <br>");
die();
***********
by
***********
// register_shutdown_function("hello");
echo ("HELLO <br>");
hello()
die();
***********
then it runs as expected and the "logfile" file is created in the script's
directory.
It seems that when calling the shutdown function, all the buffered output is
immedialty sent to the client and the buffer mode is closed.
You maybe have PHP bug here, or the manual is wrong about the possibility to
retrieve the contents.
But we can notice that this also happens at the end of a script when there
is no shutdown function.
