A question I received from a reader recently asks:

I need the “intl” and “zip” php extensions installed for a project of mine but I can’t make it work. I tried running “docker-php-ext-install intl zip”…but had no success.

The official PHP Docker image readme has an example of installing PHP extensions using the image’s docker-php-ext-install script, and demonstrates how to install the underlying libraries using apt.

Let’s look at it together in this video and see how you can install the intl and zip extensions in a Docker PHP image, step-by-step.
