Ubuntu如何升级PHP？-马春杰杰

升级步骤：

之前是PHP7.2.24，比较落后，需要升级了~

(py3) root@ubuntu-s-1vcpu-1gb-sfo3-01:~/open-ai# php -v
PHP 7.2.24-0ubuntu0.18.04.16 (cli) (built: Jan 10 2023 15:47:23) ( NTS )

(py3) root@ubuntu-s-1vcpu-1gb-sfo3-01:~/open-ai# php -v

PHP 7.2.24-0ubuntu0.18.04.16 (cli) (built: Jan 10 2023 15:47:23) ( NTS )

升级步骤：

首先更新库：

sudo apt install software-properties-common -y
sudo add-apt-repository ppa:ondrej/php
sudo apt update

sudo apt install software-properties-common -y

sudo add-apt-repository ppa:ondrej/php

sudo apt update

安装PHP8.x，其实不止8.x，你要安装7.x也可以，只需要把结尾修改一下就行

sudo apt install php8.2

1	sudo apt install php8.2

接下来安装一些常用的PHP扩展：

sudo apt install php8.2-common php8.2-mysql php8.2-xml php8.2-xmlrpc php8.2-curl php8.2-gd php8.2-imagick php8.2-cli php8.2-dev php8.2-imap php8.2-mbstring php8.2-opcache php8.2-soap php8.2-zip php8.2-intl -y

1	sudo apt install php8.2-common php8.2-mysql php8.2-xml php8.2-xmlrpc php8.2-curl php8.2-gd php8.2-imagick php8.2-cli php8.2-dev php8.2-imap php8.2-mbstring php8.2-opcache php8.2-soap php8.2-zip php8.2-intl -y

安装完毕，此时输入php -v查看下最新的版本是否改变：

(py3) root@ubuntu-s-1vcpu-1gb-sfo3-01:~# php -v
