ob_end_clean - Clean (erase) the output buffer and turn off output buffering

SYNOPSIS
       bool ob_end_clean (void	)

DESCRIPTION
	This  function	discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the
       buffer's contents you have to call ob_get_contents(3) before ob_end_clean(3) as the buffer contents are discarded when  ob_end_clean(3)	is
       called.

	The  output  buffer  must  be  started	by ob_start(3) with PHP_OUTPUT_HANDLER_CLEANABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise
       ob_end_clean(3) will not work.

RETURN VALUES
	Returns TRUE on success or FALSE on failure. Reasons for failure are first that you called the function without an active buffer  or  that
       for some reason a buffer could not be deleted (possible for special buffer).

ERRORS
/EXCEPTIONS
	If the function fails it generates an E_NOTICE.

EXAMPLES
	The following example shows an easy way to get rid of all output buffers:
