Subject: Restore output buffer in case of exceptions
From: mehmet.yavuz.selim@gmail.com ("Mehmet Yavuz Selim Soyturk")

Hello,

I'm sorry if that's the wrong list.

I am neither a PHP nor a webscripting guy so I'm sorry if this does
not make sense. I just thought that it could be useful.

PHP 5 supports exception handling. When an exception occurs, PHP does
stack unwinding so that it restores the state of the script. But an
important state of the script does not get restored: the output. Would
it not be a good idea if PHP also did some sort of output buffer
unwinding?

That is the idea:

<?php

exceptional_ob_start();

echo "Begin\n";
try {
   echo "Exception\n";
   throw new Exception();
} catch (Exception $e) {}
echo "End\n";

exceptional_ob_end_flush();

?>

And that would be the only output:

Begin
End
