1、通过修改PPA源的方式来安装

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install -y php7.2

完成后 使用 php -v 查看版本即可

如遇如下报错 ：

# LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php
More info: https://launchpad.net/~ondrej/+archive/ubuntu/php
Press [ENTER] to continue or ctrl-c to cancel adding it

dpkg-reconfigure locales

勾选

en_GB.UTF-8... done
en_HK.UTF-8... done
en_SG.UTF-8... done
en_US.UTF-8... done
zh_CN.UTF-8... done
zh_HK.UTF-8... done
zh_SG.UTF-8... done
zh_TW.UTF-8... done

export LC_ALL=C.UTF-8

也可以使用同一个ppa源 安装 7.0、7.1

sudo apt-get install -y php7.0

sudo apt-get install -y php7.1

2、安装对应的php 模块

2.1先查询出对应的模块

sudo apt-cache search php7*

2.2 将需要的模块进行安装

sudo apt-get install php7.2-mysql php7.2-curl php7.2-json php7.2-cgi php7.2-xsl
