One nit and LGTM

I stumbled upon this PR during a migration to PHP 8.3:

array_sum() and array_product() now warn when values in the array cannot be converted to int/float.

This seems to be not the case. As we can see at https://3v4l.org/lKNfW#v8.3.20, the value (string) 3Hallo is converted to 3. So either the warning Warning: A non-numeric value encountered in or the documentation is not right.

Since cannot be converted to int/float. is not the case here, does this mean the documentation is inaccurate?

I think we should reword the part in the documentation, at least we should fix some grammar issues (where => were):

+ array_sum() and array_product() now warn when values in the array cannot be converted to int/float. Previously arrays and objects were ignored whilst every other value was cast to int. Moreover, objects that define a numeric cast (e.g. GMP) are now casted instead of ignored.

Please open a new issue. Old PRs are basically never read nor the proper place to discuss stuff.

For the grammar issues feel free to open a PR.
