Util

bufferOutput()

How to get the output of another Horde function back as a string, even if that function itself outputs directly to the browser:

$html = Util::bufferOutput(array($formnew, 'renderActive'), $RENDERER, $vars, 'manageforum.php', 'post');

Which is the same as the following function being called:

$formnew->renderActive($RENDERER, $vars, 'manageforum.php', 'post');

... but we now have its output in the $html variable.
