how to upgrade from php 7.0 to php 7.3 on Debian 9.1

I have a Debian 9.1 droplet on DigitalOcean. 1GB Memory, 30GB Disk.

I've previously installed php 7.0 using apt install php php-fpm

I also ran the following commands to install php modules: apt-get install php-mysql apt-get install php-curl apt-get install php-zip apt-get install php-apcu apt-get install php-xml

How do I now upgrade from 7.0 to 7.3?

Solution

  • Just to give you an idea of how you can do it:

    Basically, you need to follow two steps:

    1. Install the 7.3 version as you did for 7.0 (you can pass the version number to install the exact version number)

    2. You need to configure your PHP CLI to use the new version 7.3 instead of 7.0.

    The above steps can be done for every version.

    Here is documentation of how you can do it in case of migration from 7 to 8.

    NOTE: The documentation will help you to install a version of PHP and configure CLI so you need to make sure to do the updates as per 7.3.
