1、查看php版本： php －v
5.5.29
2、使用homebrew安装php7
brew update #更新源
brew search php #查找源中的php，发现有php7.1版本，安装最新的php7.1
brew install php72
3、install 成功后根据提示修改相应的文档
<FilesMatch .php$>
SetHandler application/x-httpd-php
</FilesMatch>
Finally, check DirectoryIndex includes index.php
DirectoryIndex index.php index.html
The php.ini and php-fpm.ini file can be found in:
/usr/local/etc/php/7.2/
To have launchd start php now and restart at login:
brew services start php
Or, if you don't want/need a background service you can just run:
php-fpm
