推荐答案

首先通过sudo php -v检查您拥有哪个php版本.我有php7，所以结果是:

First check which php version you have by sudo php -v. I have php7 so the result is:

PHP 7.0.18-0ubuntu0.17.04.1 (cli) (built: Apr 26 2017 23:59:48) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
with Zend OPcache v7.0.18-0ubuntu0.17.04.1, Copyright (c) 1999-2017, by Zend Technologies

因为我有php7，所以我将执行以下操作以列出php软件包

since i have php7, I will do the following to list the php packages

sudo apt-cache search php7-*
