nix-phps

This is a repository of Nix package expressions for old versions of PHP.

[!CAUTION] Do not use versions other than the currently supported ones for public facing services. The older versions contain many security vulnerabilities and we do not have resources to backport security fixes. They are provided for development purposes only.

[!WARNING] Backwards compatibility is not guaranteed, pin this repo if you want to avoid breakage.

Why?

PHP projects like selfoss aim to support Linux distributions that maintain their own forks of no-longer-supported PHP versions (e.g. Debian). To be able to test those PHP versions in CI, we need Nix expressions for them. Since Nixpkgs avoids unmaintained software, we maintain those expressions here.

How to use?

We use Cachix to store x86_64-linux binaries of the built packages. Install it as described in its docs and then add the cache using cachix use fossar if you want to avoid building those PHP packages yourself.

This package is regularly updated to match latest Nixpkgs and the PHP packages use the same API as those in Nixpkgs.

The following versions are currently available:

• php56 INSECURE!
• php70 INSECURE!
• php71 INSECURE!
• php72 INSECURE!
• php73 INSECURE!
• php74 INSECURE!
• php80 INSECURE!
• php81
• php82
• php83
• php84

There is also a php package which is the alias of the default PHP version in Nixpkgs.

With niv

Assuming you have niv installed and initialized in your project, run niv add fossar/nix-phps.

Then, you will be able to use the PHP package, e.g. in shell.nix:

{
  sources ? import ./nix/sources.nix
}:

let
  nivOverlay =
    final:
    prev:
    {
      niv = (import sources.niv {}).niv;
    };

  pkgs = import sources.nixpkgs {
    overlays = [
      nivOverlay
    ];
    config = {
    };
  };

  phps = import sources.nix-phps;
in

pkgs.mkShell {
  buildInputs = [
    phps.packages.${builtins.currentSystem}.php

    # for easy updating
    pkgs.niv
  ];
}

With Nix flakes

Warning: Nix flakes are experimental technology, use it only if you are willing to accept that you might need to change your code in the future.

Add this repository to the inputs in your flake.nix’s:

  inputs = {
    …
    phps.url = "github:fossar/nix-phps";
  };

then, in outputs, you will be able to use the PHP package

  outputs = { self, nixpkgs, phps, ... }: {
    devShell.x86_64-linux = nixpkgs.legacyPackages.x86_64-linux.mkShell {
      buildInputs = [
        phps.packages.x86_64-linux.php
      ];
    };
  };
