note 102567 added to function.ob-get-clean

Also, don't forget that you will need to ob_start() again for any successive calls:

ob_start();
echo "1";
$content = ob_end_clean();

ob_start(); // This is NECESSARY for the next ob_end_clean() to work as intended.
echo "2";
$content .= ob_end_clean();

echo $content;

Output: 12

Without the second ob_start(), the output is 21 ...
