Debian oldstable and stable packages are provided as well: https://deb.sury.org/#debian-dpa You can get more information about the packages at https://deb.sury.org IMPORTANT: The <foo>-backports is now required on older Ubuntu releases. BUGS&FEATURES: This PPA now has a issue tracker: https://deb.sury.org/#bug-reporting CAVEATS: 1. If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman 2.

We can now install php 8.
Step 3 : Install different version of PHP
For apache you can now install any version
$ sudo apt install php5.6 [PHP 5.6]
$ sudo apt install php7.0 [PHP 7.0]
$ sudo apt install php7.1 [PHP 7.1]
$ sudo apt install php7.2 [PHP 7.2]
$ sudo apt install php7.3 [PHP 7.3]
$ sudo apt install php7.4 [PHP 7.4]
$ sudo apt install php8.0 [PHP 8.0]
For Nginx
$ sudo apt install php5.6-fpm [PHP 5.6]
$ sudo apt install php7.0-fpm [PHP 7.0]
$ sudo apt install php7.1-fpm [PHP 7.1]
$ sudo apt install php7.2-fpm [PHP 7.2]
$ sudo apt install php7.3-fpm [PHP 7.3]
$ sudo apt install php7.4-fpm [PHP 7.4]
$ sudo apt install php8.0-fpm [PHP 8.0]In this way you can install any version.
Install modules for any version
Simply type the version you want to install then type tab to show available module for specific module.
Example:
$ sudo apt install php7.0 php7.0 php7.0-inotify php7.0-readline php7.0-amqp php7.0-interbase php7.0-recode php7.0-apcu php7.0-intl php7.0-redis php7.0-apcu-bc php7.0-json php7.0-rrd php7.0-ast php7.0-ldap php7.0-smbclient php7.0-bcmath php7.0-lua php7.0-snmp php7.0-bz2 php7.0-lz4 php7.0-soap php7.0-cgi php7.0-mailparse php7.0-sodium php7.0-cli php7.0-mbstring php7.0-solr php7.0-common php7.0-mcrypt php7.0-sqlite3 php7.0-curl php7.0-memcache php7.0-ssh2 php7.0-dba php7.0-memcached php7.0-stomp php7.0-decimal php7.0-mongodb php7.0-sybase php7.0-dev php7.0-msgpack php7.0-tideways php7.0-ds php7.0-mysql php7.0-tidy php7.0-enchant php7.0-oauth php7.0-uploadprogress php7.0-facedetect php7.0-odbc php7.0-uuid php7.0-fpm php7.0-opcache php7.0-vips php7.0-gd php7.0-pgsql php7.0-xdebug php7.0-gearman php7.0-phalcon3 php7.0-xhprof
Example:

Now, we have installed multiple versions of php but at a time we can use one so let’s choose one PHP version
Step 1 : To check available versions of PHP
sudo update-alternatives --config phpOutput:
There are 2 choices for the alternative php (providing /usr/bin/php). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/php7.4 74 auto mode 1 /usr/bin/php7.0 70 manual mode 2 /usr/bin/php7.4 74 manual mode Press <enter> to keep the current choice[*], or type selection number:
Enter the number and you have successfully changed the version of PHP.
Step 2 : Check version of php
$ php -v
