How to update php 7.0 to php 7.1+ ubuntu
提问by Billy Joe
I have seen some help on this online but for other distros. Before I screw something up, I would love some help on this for my exact setup which is below. This will ultimately be for upgrading Laravel to 5.6 which needs newer php version.
我在网上看到了一些帮助，但对于其他发行版。在我搞砸之前，我希望在这方面为我的确切设置提供一些帮助，如下所示。这最终将用于将 Laravel 升级到需要更新 php 版本的 5.6。
Ubuntu LTS, MariaDB, nginx, Laravel 5.5, AWS EC2 instance

I was also wondering how to update to the latest 7.1.* version. I had PHP 7.1.7 but for Symfony 4 I need >=7.1.8. I coudn't find an explanation how to updated. Finally I check how I installed the latest version:
我还想知道如何更新到最新的 7.1.* 版本。我有 PHP 7.1.7 但对于 Symfony 4 我需要 >=7.1.8。我找不到如何更新的解释。最后我检查一下我是如何安装最新版本的：
apt-get install php7.1-curl php7.1-dev php7.1-zip php7.1-fpm php7.1-gd php7.1-xml php7.1-mysql php7.1-mcrypt php7.1-mbstring php7.1-opcach
As there is no minor vesion, I thought I try the same command again. And bingo, it did the update to the lasted minor verion: 7.1.22.
由于没有小版本，我想我再次尝试相同的命令。和宾果游戏，它对持续的次要版本进行了更新：7.1.22。

Use Vagrant + Docker You can use Vagrant + Docker to replicate your environment except for PHP which will be 7.1 and see if the app is still working :)
Use static analysis tools Before you start you can also use some static analysis tools to check for deprecated code: https://github.com/exakat/php-static-analysis-tools
Check offical PHP documentation http://php.net/manual/en/migration71.php
