第一步：设置brew
brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
第二部：安装php7
brew install php70 (建议使用下面的方式)
brew install php70 --with-apxs2 --with-apache --with-gmp --with-imap --with-tidy --with-debug
报错了？
configure的时候，报错了：
checking for ZLIB support... yes
checking if the location of ZLIB install directory is defined... no
configure: error: Cannot find libz
但是，我查看 libz 其实是有安装的。
brew search zlib
homebrew/dupes/zlib ✔ lzlib
（如果报错了需要安装xcode-select，我的没报错！）
安装 xcode-select
xcode-select--install
会弹框出来。点击安装就可以了：
安装好了之后。继续
brew install php70
一段时间之后，安装成功了。

打开 index.php 里的phpinfo()看是否是php7.0.4版本了。
