add-apt-repository ppa:ondrej/php

通过运行删除以前的源

sudo add-apt-repository --remove ppa:ondrej/php
sudo apt update

您需要按如下方式编辑存储库源文件：

sudo nano /etc/apt/sources.list

然后输入

deb https://ppa.launchpadcontent.net/ondrej/php/ubuntu jammy main

然后运行

sudo apt update

之后您现在应该能够以 8.3 为例安装您的 php 版本

sudo apt install php8.3

如果您已经安装了其他一些 php，您可能需要使用
更改为版本

sudo update-alternatives --config php

然后按照提示操作。

您还可以考虑安装以下扩展

sudo apt install php8.3-curl php8.3-gd php8.3-intl php8.3-simplexml php8.3-dom php8.3-mysql php8.3-mbstring php8.3-xml php8.3-gd php8.3-curl php8.3-mysqli php8.3-zip
