如何安装php7

---

我使用的是Ubuntu14.04，但我希望答案与操作系统无关。

对于在Ubuntu14.04系统中安装php7，请遵循以下步骤：

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.0

用于mysql

sudo apt-get install php7.0-mysql
sudo service apache2 restart

---

如果要删除php5，则在安装php7后，请执行以下步骤：

sudo apt-get update
sudo apt-get purge php5-common -y
sudo apt-get install php7.0 php7.0-fpm php7.0-mysql -y
sudo apt-get --purge autoremove -y

我分享了我在Ubuntu 18.04.1上安装PHP 7.0.33-8版的方式。我还发布了成功安装后我的

返回内容的屏幕截图。请参见以下我遵循的步骤：

更新1:

sudo apt-get update
sudo apt-get purge php5-common -y
sudo apt-get install php7.0 php7.0-fpm php7.0-mysql -y
sudo apt-get --purge autoremove -y

根据您的要求，k0pernikus，字面上是如何在Antonio Lopez的《学习PHP 7》第1章中发表的，由Packt Publishing出版：

安装PHP

本节中唯一要考虑的是删除以前的任何部分。 系统上的PHP版本。为此，您可以运行以下命令 命令：

$sudo apt get-y purge php.*

下一步是添加必要的存储库以获取 正确的PHP版本。添加和更新它们的命令有：

$sudo apt get install python软件属性

$sudo LC_ALL=en_US.UTF-8添加apt存储库ppa:ondrej/php-y

$sudo apt获得更新

最后，我们需要将PHP7与MySQL驱动程序一起安装。 为此，只需执行以下三个命令：

$sudo apt get安装php7.0 php7.0-fpm php7.0-mysql-y

$sudo apt get--purge autoremove-y

$sudo apt get--purge autoremove-y

$sudo服务php7.0-fpm启动

我不知道

apt-get

是否已更新，您是否尝试过

apt-get-update

并尝试过安装

php7

？在任何情况下，我很确定在askubuntu中提出的解决方案仍然有效。在askubuntu上，有一个和一个相关的@Havenard，我尝试过，但失败了。你自己试过了吗？：）几次失败的测试。他们大多数人都预料到了。您的PHP7可能工作正常。除了curl扩展之外，因为Ondrey是Debian中PHP树的官方所有者，所以PPA是相当值得信赖的。尽管如此，我们还是应该考虑到附加存储库可能会安装所有内容，并可能带来安全风险。记住这一点，我也在使用它。你能把输出减少到实际输入的命令吗？您有十个命令，其余的只是它们的输出（不需要全部发布）。只有在命令的输出真正有意义时才发布它。考虑到这一点，我看不出答案有什么不同，因为这似乎也在使用

ondrej/php

ppa方法。@k0pernikus完成。见我的更新1。
