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
	      (
	      )
