This article completely solves the installation and version switch of PHP on Ubuntu

Official sources on Ubuntu. For example, PHP5.6.x and Ubuntu16.04 are the default sources PHP7.0.x. What should I do if I want to install PHP7.1 and PHP7.2 on Ubuntu16.04?

The answer is to install it through a third-party source. ppa: ondrej/php is a well-known PHP source (currently maintaining php5.6, php7.0, php7.1, php7.2 ). Next we will use this source to install the desired PHP version.

1. install PHP from the source

Sudo add-apt-repository ppa: ondrej/php
Sudo apt-get update
Sudo apt-get upgrade
Sudo apt-get install php7.1 # for PHP 7.1
Sudo apt-get install php7.0 # for PHP 7.0
Sudo apt-get install php5.6 # for PHP 5.6

2. Install the PHP module of the relevant version.

Sudo apt-cache search php7 *
...
Php-all-dev-package depending on all supported PHP development packages
Php7.0-server-side, HTML-embedded scripting language (metapackage)
Php7.0-cgi-server-side, HTML-embedded scripting language (CGI binary)
Php7.0-cli-command-line interpreter for the PHP scripting language
Php7.0-common-documentation, examples and common module for PHP
Php7.0-curl-CURL module for PHP

Php7.2-cli-command-line interpreter for the PHP scripting language
Php7.2-common-documentation, examples and common module for PHP
Php7.2-curl-CURL module for PHP
Php7.2-dba module for PHP

3. Select the required module and install it.

Sudo apt-get install php7.2-curl php7.2-dev php7.2-gd php7.2-imap php7.2-intl php7.2-mbstring php7.2-mysql php7.2-xml php7.2-zip

4. Switch to the PHP version.

Sudo update-alternatives -- config php

5. Set Apache to run with the correct PHP version.

Sudo a2dismod php7.1 # unload the current version
Sudo a2enmod php5.6 # load the version you need
Sudo service apache2 restart # restart webserver to apply

By now, you no longer have to worry about installing PHP and switch to the PHP version.
