Hi, I tried the wasm build of python, ruby and php with my wasmer runtime, python and ruby are good, but the PHP only provide wasmedge version which could not run under the latest wasmer v4.2.3.

> wasmer python-3.11.4.wasm --dir . hello.py
Hello World

> wasmer ruby-3.2.2.wasm --dir . hello.rb
Hello World

> wasmer php-cgi-8.2.6.wasm --dir . hello.php
Status: 404 Not Found

The php-cgi CLI will need the -f option before the filename. This should work.

wasmer php-cgi-8.2.6.wasm --dir . -f hello.php

We only offer the full PHP interpreter flavored for WasmEdge as we've based it's socket implementation on top of WasmEdge sockets. We did not find it useful (at this time) to invest into cutting all the socket-related code from the php CLI and offering a version with that. php-cgi seemed enough for most use-cases, as it is what runs in most traditional deployments.

Let me know if the above line fixes your use-case. If that's so I would close the issue for now.

@assambar Thanks, now I see some difference about php-cgi and php.

I tried wasmer php-cgi-8.2.6.wasm --dir . -f hello.php, but it did not work for me, I still could not use wasmer/wasmedge php-cgi to run an echo hellworld example.

Did I miss something? It seemed I could not pass hello.php to php-cgi.

And another question, why php cli needs socket while php-cgi does not?

It's really strange, I can pass the file to python-3.11.4.wasm. But the same method did not work for php-cgi-8.2.6.wasm.

I can use pipe stdin to make it work.
