采用php开发终端字符界面
2009年6月1日
众所周知，PHP通常情况下都用于动态网站的开发，抑或采用PHP_CLI进行命令行的开发。其实PHP除了能进行以上两种开发外，还可以进行终端系统的开发。
废话以后再讲，先上个图一看便知。
这个界面没见过？不会吧，各位XD去过银行吧？留心看过其操作界面没有？想起来了？对了，他们的操作界面就是类似于这个东东。当然这只是一个登录界面而已。虽然这只是一个登录界面，但其所有代码均采用PHP完成，没想到吧？
那就来看看Code:
<?php
define('MY_NCURSES_KEY_ESC', 27);
define('MY_NCURSES_KEY_NUM_MIN', 48);//0
define('MY_NCURSES_KEY_NUM_MAX', 57);//9
define('MY_NCURSES_KEY_INPUT_MIN', 65);//A
define('MY_NCURSES_KEY_INPUT_MAX', 122);//z

现在明白是怎么回事了吧？当然各位兄弟把这代码拿下去，可能你们的环境中是无法RUN的，因为这采用了其它的PHP包。
对于采用的什么包，各位XDJM，还敬请关注本博，稍后将奉上相关的PHP包的安装与配置 ：）
