How to Properly Install php-zip on a php:7.4-fpm Docker Image

When working with PHP applications, especially those that require the use of libraries like PhpWord, installing the necessary extensions can sometimes become a hurdle. If you've landed on this article, you're likely facing a frustrating issue while trying to install php-zip on your php:7.4-fpm Docker image.

In the following sections, we’ll dive deep into the problem at hand, how it manifests, and the tried-and-tested solution that can help you move forward.

The Problem

While attempting to install php-zip, you may come across an error stemming from missing dependencies. Here’s a brief overview of the situation:

You are working with the php:7.4-fpm Docker image based on Debian.

Your Dockerfile contains a command to install the zip extension using:

This command fails due to an inability to find the required files, specifically /usr/src/php/ext/libzip.

When attempting to install libzip or libzip4, you encounter additional errors indicating that these packages cannot be found or do not meet the required version criteria.

Understanding the Solution

The misstep here is related to the specific package name required for installation. To successfully install the php-zip extension, you are actually looking for libzip-dev. This package contains the development files necessary for compiling the zip extension.

Here’s how you can resolve the installation issue:

Step-by-Step Solution

Update the Package Lists: Start by updating the package lists to ensure you have the latest information from the repositories.

Install libzip-dev: The correct package to install is libzip-dev, not just libzip or libzip4.

Install the PHP zip Extension: After installing the necessary development files, you can proceed to install the zip extension using Docker PHP’s installation command.

Updated Dockerfile Command

Your Dockerfile should therefore include the following lines:

Explanation of Each Command

apt-get update: This command refreshes the local package index with the latest available versions.

apt-get install -y libzip-dev: This command installs libzip-dev, providing essential files for development.

docker-php-ext-install zip: This command compiles and installs the zip extension for PHP.

Final Thoughts

Following these steps will ensure that you can successfully install php-zip in your php:7.4-fpm Docker image, allowing you to move ahead with using the PhpWord library or any other need for the zip functionalities in your PHP application.

Don't hesitate to experiment and modify your Dockerfile as necessary. With each build, you'll become more adept at managing dependencies within your Docker containers!
