Mac brew 升级 php7.2 并设置为默认

mac 升级PHP 到 7.2

whereis php 
php -v

系统默认自带的是 PHP5.6，需要升级到最新版本 PHP7.2

brew install php72
brew info php72
brew --prefix php

中途可能要升级 xcode-select

修改 ~/.bash_profile

user:~ sl$ cat ~/.bash_profile 

# The original version is saved in .bash_profile.pysave
PATH="$(brew --prefix php)/bin:$PATH"
export PYTHON_ENV=development

user:~ sl$ source ~/.bash_profile 
user:~ sl$ php -v
user:~ sl$ php -v
