Warning

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担。

Disables line buffering and character processing (interrupt and flow control characters are unaffected), making characters typed by the user immediately available to the program.

re satoru's post,
While it's not using cbreak, it sorta is an example. The only difference between raw and cbreak is how control keys are delt with.

Quoted from the ncurses_programming_howto:
Normally the terminal driver buffers the characters a user types until a new line or carriage return is encountered. But most programs require that the characters be available as soon as the user types them. The above two functions are used to disable line buffering. The difference between these two functions is in the way control characters like suspend (CTRL-Z), interrupt and quit (CTRL-C) are passed to the program. In the raw() mode these characters are directly passed to the program without generating a signal. In the cbreak() mode these control characters are interpreted as any other character by the terminal driver.
