I'm upgrading the php version to 7.0 in my docker image which is based on Ubuntu 14.04. I read some articles giving the commands to uninstall php5 while installing php7.0. Is this really necessary? What are the pros and cons?

推荐答案

为PHP 7添加新的存储库:

add the new repository for PHP 7:

 apt-get install software-properties-common
 add-apt-repository ppa:ondrej/php

从系统中删除PHP 5并安装PHP 7

remove PHP 5 from your system and install PHP 7

 apt-get update && apt-get purge php5-fpm && apt-get --purge autoremove && apt-get install php7.0-fpm php7.0-mysql php7.0-curl php7.0-gd php7.0-json php7.0-mcrypt php7.0-opcache php7.0-xml
