Let's see how to upgrade your PHP installation to 7.4.
sudo add-apt-repository ppa:ondrej/php # Press enter to confirm. sudo apt-get update
sudo apt install apt-transport-https lsb-release sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg # Download the signing key sudo sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list' # Add Ondrej's repo to sources list. sudo apt update
sudo apt install php7.4 php7.4-common php7.4-cli
php7.4- with an extension that you need to install.
For example to get the
php-curl extension use
sudo apt install php7.4-curl php7.4-json php7.4-gd php7.4-mbstring php7.4-intl php7.4-bcmath php7.4-bz2 php7.3-readline php7.3-zip
To integrate PHP with your web server, If you are using Nginx, or Apache with mod_event, you will need to install
php7.4-fpm package. If you are using PHP as an embedded Apache module, you will need the package
libapache2-mod-php7.4. For Apache, you can use
apachectl -V to see your current MPM, whether it’s
sudo apt install php7.4-fpm
sudo apt install libapache2-mod-php7.4 sudo a2enmod php7.4
sudo apt purge php7.3 libapache2-mod-php7.3 # For removing PHP 7.3 sudo apt purge php7.2 libapache2-mod-php7.2 # For removing PHP 7.2 sudo apt purge php7.1 libapache2-mod-php7.1 # For removing PHP 7.1 sudo apt purge php7.0 libapache2-mod-php7.0 # For removing PHP 7.0
To verify the installation of PHP 7.4
Create a file info.php. It must be saved to a very specific directory, which is called the “web root”. In Ubuntu and Debian this is located at /var/www/html/.
sudo nano /var/www/html/info.php
Type the following in the editor.
<?php phpinfo(); ?>
When you are finished, save and close the file.
Now visit this script in your browser.
You should see something similar to this.
So now you have PHP 7.4 up and running. See the migration guide for PHP 7.4 at https://www.php.net/migration74
