我现在应该怎么做？
答案1
Ubuntu 16.04 LTS 附带 PHP 7.0。要安装它，您需要运行：
sudo apt-get install php
或者选择一个特定的 PHP Web SAPI，很可能您需要对 Apache2 的支持：
sudo apt-get install libapache2-mod-php php
或者 PHP FPM
sudo apt-get install php-fpm php
如果您特别需要 PHP 5.x，则需要使用ppa:ondrej/php并安装适用于 Apache2 的 PHP 5.6：
sudo apt-get install php5.6 libapache2-mod-php5.6
答案2
16.04 在官方存储库中没有 PHP 5。安装 14.04 系统，或使用此 PPA。
