Ubuntu 20.04 | 18.04系统安装PHP 8.0详细过程

PHP是一种流行的Web开发脚本语言,最初由丹麦裔加拿大程序员Rasmus Lerdorf在1994年创建。他所创建的PHP脚本可以在Linux、macOS、Windows和许多其他Unix系统上执行,前提是已安装PHP环境。

在本文中,小编将简单说明在Ubuntu 20.04 | Ubuntu 18.04 Linux系统上安装PHP 8.0版本的简单过程,有需要安装PHP8.0版本的小伙伴不妨关注下。

PHP 8.0正式版本已经在2020年11月26日发布,它是一个新的主要版本,具有许多新功能和性能改进,这意味着你可能需要对代码进行一些修改才能使其在PHP 8.0上运行。PHP 8.0附带的一些不错的新功能包括JIT编译器、参数、联合类型、属性等等。

步骤1:系统更新

通过运行以下命令,将所有系统软件包更新为最新版本。

sudo apt update
sudo apt -y upgrade

升级后重新启动很重要,命令如下:

sudo systemctl reboot

步骤2:添加OndrejSuryPPA存储库

最新的PHP软件包可在OndrejSuryPPA存储库中获得,运行下面共享的命令,以将此存储库添加到您的Ubuntu系统。

sudo apt update
sudo apt install lsb-release ca-certificates apt-transport-https software-properties-common -y
sudo add-apt-repository ppa:ondrej/php

当提示您添加存储库时,按Enter键:

Debian oldstable and stable packages are provided as well: https://deb.sury.org/#debian-dpa

You can get more information about the packages at https://deb.sury.org
