Question 1

How do I install PHP extensions with PIE on Windows?

Accepted Answer

On Windows, PIE uses pre-compiled DLLs, so no build tools are needed. Download pie.phar and run commands like `pie install extension-name`, and it will automatically handle the installation, as explained in the Windows-specific prerequisites.

Question 2

PIE vs PECL: which one should I use now?

Accepted Answer

PIE is the official replacement for the deprecated PECL system. Use PIE for modern PHP projects due to its improved workflow and cross-platform support, but verify your extensions are available on Packagist for PIE, as noted in the README.

Question 3

Can PIE install extensions for multiple PHP versions on one machine?

Accepted Answer

Yes, PIE can target any installed PHP version, as shown in examples where it detects the PHP binary. You need to run PIE with the specific PHP version to install extensions for it, but PIE itself must run on PHP 8.1+.

Question 4

How to use PIE in a Docker container for automated builds?

Accepted Answer

In a Dockerfile, download pie.phar and use `pie install` with the --allow-non-interactive-project-install flag to install extensions without prompts, ensuring seamless integration in CI/CD pipelines, as recommended in the README.

Question 5

What if an extension isn't on Packagist for PIE?

Accepted Answer

If an extension isn't available, you'll need to install it manually via traditional methods or wait for the maintainer to add PIE support. The README provides documentation for extension maintainers to integrate with PIE.

Question 6

Does PIE work alongside Composer for managing dependencies?

Accepted Answer

Yes, PIE complements Composer by handling PHP extensions, while Composer manages PHP packages. Use PIE to install extensions required by your project, and it can read project configurations to automate this, as shown in the project-aware installation example.
