Nix (PHP) Shell

Description

This package provides a Nix flake ready to use for PHP development, using the Nix package manager which can be installed on (almost) any operating system.

Available stable PHP versions from 5.6 to 8.4.

To list the available PHP versions, run:

nix flake show github:loophp/nix-shell

The added value of this package is the ability to create custom PHP builds based on your project's composer.json file. This way, you can be sure that the PHP extensions you need are available in your development environment.

The PHP extensions to use are automatically inferred from the composer.json file.

...8<...

"require": {
  "ext-intl": "*",
},
"require-dev": {
  "ext-xdebug": "*",
  "ext-pcov": "*",
}

...>8...

To load extensions from the require and required-dev sections, using the flag --impure is required. Example:

nix develop github:loophp/nix-shell#php82 --impure

Usage

While being extremely stable for years, "flake" is an upcoming feature of the Nix package manager. In order to use it, you must explicitly enable it, please check the documentation to enable it, this is currently an opt-in option.

In a shell

To work with PHP 8.2 only:

nix develop github:loophp/nix-shell#php82

or with PHP 8.2 and a couple of useful tools:

nix develop github:loophp/nix-shell#env-php82

Since the 14th of November 2022, PHP is in NTS mode by default (see #154774).

To list the available PHP versions and environments, run:

nix flake show github:loophp/nix-shell

In another flake

Step 1

Import the input:

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    flake-utils.url = "github:numtide/flake-utils";
    nix-shell.url = "github:loophp/nix-shell";
  };

Step 2

Import the overlay:

pkgs = import inputs.nixpkgs {
  inherit system;
  overlays = [
    inputs.nix-shell.overlays.default
  ];
};

Step 3

Use the packages:

  # PHP 8.2
  pkgs.nix-shell.php82

To create your own version of PHP, use the available API function buildPhpFromComposer.

With direnv

direnv is an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory. You can use it within Nix (nix-direnv) and load a development environment just by changing directory.

Edit the file .envrc and add the following line:

use flake github:loophp/nix-shell#env-php-master-snapshot --impure

And it's done.

Customize PHP

To customize the PHP configuration, you can do it like this:

nix develop github:loophp/nix-shell#php82
php -c /path/to/the/config.ini <<command>>

Another option would be to create a .user.ini file within your current working directory before running the PHP environment, as such:

max_execution_time = 0
memory_limit = 2048M

Then run:

nix develop github:loophp/nix-shell#php82 --impure

The --impure flag is important to make sure that your custom .user.ini file is correctly taken in account.
