This is my (working) config. Unless something changed in between versions, you can adapt it to php74:

environment.systemPackages = with pkgs; let
   php82 = pkgs.php82.buildEnv {
     extensions = ({ enabled, all }: enabled ++ (with all; [
       xdebug
       redis
       xsl
       ffi
     ]));
     extraConfig = ''
       memory_limit=8G
       xdebug.mode=debug
     '';
  };
    in
  [
    php82
    php82.packages.composer
    php82Extensions.redis
    php82Extensions.xsl
  ];

Adam Stotesbury: Have you tried using my config?

Here's a fully working shell.nix with what you want, it can easily be adapted:

{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
    nativeBuildInputs = with pkgs.buildPackages;
    let
      custom = import (builtins.fetchTarball https://github.com/nixos/nixpkgs/tarball/0e4ade244d0f1b01a378aa58c235a1576778c1fd) {};
      php74 = pkgs.php.buildEnv {
        extensions = ({ enabled, all }: enabled ++ (with all; [
          redis
          xdebug

        extraConfig = ''

Also, you might want to use a project of mine for getting older versions, for example: https://history.nix-packages.com/search?packageName=php74

It should have the latest version the package is found in, meaning the newest available dependencies for each version

You should add the template for flake inputs ! :)
