今天翻了翻PHP手册，无意中发现这个PHP7才加入的新扩展：图形用户界面(GUI) 扩展 PHP-UI，觉得挺有意思的，2016年10月才发布的，网上搜了一圈发现几乎没有相关资讯，连安装说明都没有一个。。。
官方介绍原文：
This extension wraps the very excellent libui to provide PHP 7 with an API for the creation of cross platform native look-and-feel interfaces.
大概说的是：该扩展是适用于 PHP7 基于 libui 开发的跨平台图形界面接口吧。。。
PHP扩展介绍
Github
经过一番折腾，终于能运行了，
下面说说我的安装过程：（仅以Windows7为例）
1. 先下载扩展
扩展下载：https://pecl.php.net/package/ui
按照你本地的PHP7版本情况选择下载对应的扩展文件，注意：仅支持 PHP7 哦
2. 安装扩展
解压刚才下载的压缩包
总共需要三个 .dll 文件
php_ui.dll libui.dll pthreadVC2.dll
将 php_ui.dll 复制到 PHP 的 ext 目录下，
其余两个文件 libui.dll 和 pthreadVC2.dll 放到 PHP 的根目录下，也就是与 php.exe 的同级目录
如果你之前操作不正确，在命令行中执行 PHP 时，将会弹出下面的错误提示：
无法启动此程序，因为计算机中丢失 libui.dll，尝试重新安装该程序以解决此问题。
这个提示出现说明你没有放入 libui 和 pthreadVC2 文件到 php 的根目录下，重新放入就正常了。
3. 开始测试
打开之前下载的压缩包，其中有三个已写好的测试代码：
贪吃蛇游戏，无限星空动画，趋势图
下面运行测试代码看看效果吧：
贪吃蛇：
这是个可操作的游戏哦，不过撞到自己的尾巴不会死，窗口可任意拉伸，越大行动速度就越快
无限星空图
趋势图
可以实时调节变化。
5.源码参考：
这是官方的测试案例源码，可以先参考下看看
贪吃蛇代码：
