PHP 7.2出来有一段时间了，不出意料，memcache又不能用了，于是又想到要自己动手编译，不过与我编译PHP 7.1的memcache的时候相比，有个好消息是已经有人把PHP 7.1和7.2 的memcache都编译好并放在github上了，需要的可直接去那里下载，我这篇文章就不提供下载了：

注：这里还是要强烈吐槽一下百度，以“php 7.2 memcache”为关键字，完全搜索不到任何有用的东西，上面那个网址我是用google一下子就搜到了，而且还受到启发，顺利的把编译过程给搞定，所以搞开发的遇到技术问题，还是不要在百度上浪费生命了。
我下面还是把我研究出来的PHP 7.2 memcache的编译方法写出来，给有需要的人做个参考吧。
PHP 7.2的memcache编译方法跟之前版本有了一些变化，主要体现在：
编译前需要下载如下文件：
注意：编译前需先安装好vs2017。
