I changed the way the builder is called, from: buildPecl rec {...} to php.buildPecl rec {...}.
At first I though that the behavior would be the same as the original one, but it's not. The php version is always the same, no matter wich one I specify: nix build .#php81.extensions.mongodb or nix build .#php83.extensions.mongodb. It is still picking PHP 8.2.
How can I do to use the old behavior and just use buildPecl rec {...} ? I tried and I get this issue:

❯ nix build .#php83.extensions.mongodb -L
error: evaluation aborted with the following error message: 'Function called without required argument "buildPecl" at /nix/store/ij8r2bhqxjqahyrn09wb69hy871d6ssg-source/pkgs/development/php-packages/mongodb/default.nix:2'

Hey, I've got a weird behavior in a Nix project of mine. The project aim to maintain old versions of the PHP language.
For some reason, the builds running on Darwin are picking the newest version of OpenSSL (3), not the old one (1) despite the fact that we are doing it (https://github.com/fossar/nix-phps/blob/9d00fd85709bcd48c80530cc71fbace99c375038/pkgs/package-overrides.nix#L510).
See the Github actions run, almost all the Darwin builds are failing for the same reason: https://github.com/loophp/nix-shell/actions/runs/5635189875

Do you have a clue what it could be?

Maybe try using builtins.trace for debugging

I applied this patch:

And then I run: nix build .#php74.extensions.openssl -L

I can see: 1.1.1u.

It would be nice to do the same on a Darwin machine.

I can see: openssl-1.1.1u, so the replacement works. But it seems it is not on Darwin... any available to verify ?
