步骤1：首先，最好使用此命令从您的Ubuntu删除php。
只会删除php及其模块
sudo apt-get purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`
第2步： PHP 7.1在Ubuntu默认存储库上不可用…为了安装它，
您将不得不从第三方存储库中获取它。
运行以下命令以添加以下第三方存储库以安装PHP 7.1
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
步骤：3 现在安装所需的模块。
sudo apt-get install php7.1 libapache2-mod-php7.1 php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-zip php7.1-curl composer
