PIE is a new installer for PHP extensions, intended to eventually replace PECL. It is distributed as a PHAR, just like Composer, and works in a similar way to Composer, but it installs PHP extensions (PHP Modules or Zend Extensions) to your PHP installation, rather than pulling PHP packages into your project or library.

You will need PHP 8.1 or newer to run PIE, but PIE can install an extension to any installed PHP version.

On Linux, you will need a build toolchain installed. On Debian/Ubuntu type systems, you could run something like:

sudo apt install gcc make autoconf libtool bison re2c pkg-config php-dev

On Windows, you do not need any build toolchain installed, since PHP extensions for Windows are distributed as pre-compiled packages containing the extension DLL.

If you are an extension maintainer wanting to add PIE support to your extension, please read extension-maintainers.

• Download pie.phar either:
  • latest stable release
  • latest unstable nightly
• Verify the PHAR's source with gh attestation verify --owner php pie.phar
• You may then invoke PIE with php pie.phar <command>

Further installation details can be found in the usage docs. This documentation assumes you have moved pie.phar into your $PATH, e.g. /usr/local/bin/pie on non-Windows systems.

A list of extensions that support PIE can be found on https://packagist.org/extensions.

You can install an extension using the install command. For example, to install the example_pie_extension extension, you would run:

$ pie install example/example-pie-extension This command may need elevated privileges, and may prompt you for your password. You are running PHP 8.3.10 Target PHP installation: 8.3.10 nts, on Linux/OSX/etc x86_64 (from /usr/bin/php8.3) Found package: example/example-pie-extension:1.0.1 which provides ext-example_pie_extension phpize complete. Configure complete.

When in your PHP project, you can install any missing top-level extensions:

$ pie install 🥧 PHP Installer for Extensions (PIE), 0.9.0, from The PHP Foundation You are running PHP 8.3.19 Target PHP installation: 8.3.19 nts, on Linux/OSX/etc x86_64 (from /usr/bin/php8.3) Checking extensions for your project your-vendor/your-project requires: curl ✅ Already installed requires: intl ✅ Already installed requires: json ✅ Already installed requires: example_pie_extension ⚠️ Missing The following packages may be suitable, which would you like to install: [0] None [1] asgrim/example-pie-extension: Example PIE extension > 1 > 🥧 PHP Installer for Extensions (PIE), 0.9.0, from The PHP Foundation > This command may need elevated privileges, and may prompt you for your password. > You are running PHP 8.3.19 > Target PHP installation: 8.3.19 nts, on Linux/OSX/etc x86_64 (from /usr/bin/php8.3) > Found package: asgrim/example-pie-extension:2.0.2 which provides ext-example_pie_extension ...
