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();
?>
