PHP Custom Runtime on Alibaba Cloud Function Compute

This repository contains PHP build scripts tailored for Function Compute, starting with PHP 8.0.

Function Compute supports three distinct custom runtimes: custom, custom.debian10, and custom.debian11. As their names suggest, these runtimes are based on Debian 9, Debian 10, and Debian 11, respectively.

Build

Each PHP version is built using a specific builder aligned with its runtime environment. Additionally, dedicated folders are provided to handle edge cases and runtime-specific customizations.

To support future PHP versions, simply duplicate the folder containing the latest supported PHP version and make necessary modifications until it functions properly.

Let's say you're building PHP 8.4 with custom.debian11 runtime environment and want to test the build:

make build-php84-debian11

Under the hood, we use Docker to isolate the building environment, install all the necessary dependencies PHP requires and compile it from source.

Furthermore, in order to optimize the build and reduce its size, we extract only the essential files and strip away all symbols and debugging information from the PHP executables, making it as compact as possible.

Before publishing new version of custom runtime as a layer for all the supported PHP versions, there's a shortcut for building all the PHP versions we currently support.

make build
