一、安装自己需要的版本php
- 以php7.1为例，执行：curl -s https://php-osx.liip.ch/install.sh | bash -s 7.1
（去这个链接下找自己想要下载的php版本 https://php-osx.liip.ch/）
- 安装结束后，/usr/local/php5目录下即刚刚install的php
- 此时在终端中输入php －v 显示的还是老的版本，可以将这个新的PHP路径追加到$path中。
vi ~/.profile
在文件中增加以下一行
export PATH=/usr/local/php5/bin:/usr/local/php5/sbin:$PATH
执行下面的命令使改动立即生效
source ~/.profile
- 此时运行php -v，已经是刚刚安装的7.1版本
