ob_clean — Clean (erase) the output buffer
This function discards the contents of the output buffer.
This function does not destroy the output buffer like ob_end_clean() does.
The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_CLEANABLE flag. Otherwise ob_clean() will not work.
