I've worked with mostly PHP from this era, or at least developers that are from this era. The code still runs fine, and not having things like return types don't make the code less able to run (just not as easy to catch bugs).

I haven't used Zed, but can you choose the PHP version, or point to a PHP executable for warnings/errors? I know in VS Code, you point to the PHP executable for the version you are using, to catch errors. I haven't created a new PHP project in quite some time, but I did work on many older PHP projects, and never had this issue with VS Code. I suspect even if you don't go about it this way, there has to be configuration to specify what is and isn't an error vs. warning.
