ob_get_flush - Flush the output buffer, return it as a string and turn off output buffering

SYNOPSIS

       string ob_get_flush (void  )

DESCRIPTION

       ob_get_flush(3) flushes the output buffer, return it as a string and turns off output buffering.

	The output buffer must be started by ob_start(3) with PHP_OUTPUT_HANDLER_FLUSHABLE flag. Otherwise ob_get_flush(3) will not work.

       Note

	       This function is similar to ob_end_flush(3), except that this function returns the buffer as a string.

RETURN VALUES

	Returns the output buffer or FALSE if no buffering is active.

EXAMPLES

       Example #1

	      ob_get_flush(3) example

	      <?php
	      //using output_buffering=On
	      print_r(ob_list_handlers());

	      //save buffer in a file
	      $buffer = ob_get_flush();
	      file_put_contents('buffer.txt', $buffer);

	      print_r(ob_list_handlers());
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => default output handler
	      )
	      Array
	      (
	      )

OB_END_CLEAN(3) 							 1							   OB_END_CLEAN(3)

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:

       Example #1

	      ob_end_clean(3) example

	      <?php
	      ob_start();
	      echo 'Text that won't get displayed.';
	      ob_end_clean();
	      ?>
