We assuming that you have have php 7.0 installed in your server. Please follow the and upgrade the php version from php 7.0 to php 7.1.

Step 1: Add ondrej/php PPA.

If you get a command not found error for add-apt-repository, you can install it from:

sudo apt-get install software-properties-common python-software-properties

Now, make sure to install the additional packages as you need them. In my case, I also installed these packages with apt-get command.

sudo apt-get install php7.1-curl php7.1-xml php7.1-zip php7.1-gd php7.1-mysql php7.1-mbstring

Step 5: Remove old 7.0 packages
If everything works great, you can remove the old packages now.

sudo apt-get purge php7.0 php7.0-common

Step 6: Start the web server. Run the following command and see the php version

php -v
