When your script exits, after ncurses_clear() was called, it could leave your terminal in an inconsistent state.

Therefore, you should call ncurses_savetty() in a constructor and nurses_resetty() in a destructor, to ensure, that your terminal is working fine after your script exits.

Here is an example code snippet, on how to use this function, without falling into trouble ;-)

<? // PHP5 Example

class foo
{
   
/* Foo constructor */
   
function __construct()
    {
       
/* Initialize ncurses first */
       
ncurses_init();

       
/* Save your tty !!! */
       
ncurses_savetty();
    }

    function
bar ()
    {
       
/* Clear the screen and wait a few seconds */
       
ncurses_clear();

       
sleep(5);
    }

   
/* Foo destructor */
   
function __destruct()
    {
       
/* Restore your terminal settings */
       
ncurses_resetty();

       
/* End ncurses and clean up */
       
ncurses_end();
    }

}

$test_ncurses = new foo;
$test_ncurses->bar();
?>
