Answer 1

You need to follow the below steps for updating:

1. Add PPA repository for PHP

sudo apt install software-properties-common sudo add-apt-repository ppa:ondrej/php

2. Update Ubuntu

Open terminal and run the following commands to update Ubuntu packages.

sudo apt-get update

3. Install PHP (Whichever version you wanna install like 7.4 8 etc)

sudo apt install php7.4

Check php version

sudo php -v

4. Install PHP Extensions (Optional)

PHP extensions are commonly used along with PHP. Install them with the following command.

sudo apt install php7.4-common php7.4-mysql php7.4-xml php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl -y

5. Enable PHP 7.4 for Apache

Next you need to disable your old PHP (say 7.0) and enable new PHP 7.4.

sudo a2dismod php7.0 sudo a2enmod php7.4

6. Restart Apache Server

Restart Apache web server to apply changes

sudo service apache2 restart
