Problem with ob_get_contents()

["Prathaban Mookiah" <prathap@xxxxxxxxxxxx>]

Hello,

I've posted a miniature version of my code here to explain my problem.

<CODE>

<?
phpinfo();

ob_start();

register_shutdown_function("hello");

echo ("HELLO");

die();

function hello()
{

$logfile = "logfile";

$error_string = ob_get_contents();

if(!$handle = fopen($logfile, "a"))
{
        echo("Could not open logfile for writing!");
        ob_end_flush();
        exit;
}

if(fwrite($handle, $error_string) === FALSE)
{
        echo("Could not write to logfile!");
        ob_end_flush();
        exit;
}

fclose($handle);

ob_end_clean();

}

?>

</CODE>

This simply does not work the way it should. i.e ob_get_contents doen't return 
any string and the buffer just gets flushed by itself at termination.

Though the PHP manual says it is not possible to retrieve the contents of any 
output buffers using ob_get_contents() with PHP < 4.0.6. But I am using PHP 5.
x.x

Thanks in advance for any help.
