That's my proposed patch, although I am fairly new to PHP internals and not
sure
how robust it is.

Description:
------------
If ob_start() callback returns an empty string then nothing should be printed.
This is the current behavior in PHP 5.3. Behavior in PHP 5.4 is different - if
a callback returns an empty string then the result is same as if it wouldn't be
called at all - next call is prepended by last call value.
So there is no way for callback how to discard the output.
Test script:
---------------
ob_start(function ($s) {
fwrite(STDERR, strlen($s) . "\n");
if ($s == "b\n") {
return $s;
}
return "";
}, 2);
echo "a\n";
echo "b\n";
exit;
Expected result:
----------------
2
2
b
0
Actual result:
--------------
2
4
4
