Amphp Parallel on Frankenphp Windows

[Serveronet]

When using Amphp Parallel on Windows it ends with "Could not locate PHP executable binary".
It tries to find a php.exe which is not installed.
However Frankenphp bundles php.exe so there's no need.

Have a look here:
https://github.com/amphp/parallel/blob/296b521137a54d3a02425b464e5aee4c93db2c60/src/Context/ProcessContext.php#L188

Is this something that could happen on Frankenphp side or rather Amphp? Or env variable would be a workaround?

I don't see how this related to FrankenPHP at all.

There's a set of constants, for example PHP_OS, PHP_VERSION, which is defined by the PHP engine.
PHP_BINARY or PHP_BINDIR could be defined as well since it's bundled with Frankenphp. Does it make sense?

[henderkes]

All of those are defined. I don't understand what behaviour you are expecting here:

❯❯ build  17:46 php .\phpbin.php
C:\php\php.exe
C:\php
❯❯ build  17:47 frankenphp php-cli .\phpbin.php
C:\php\frankenphp.exe
C:\php

Since frankenphp.exe won't be suitable for their purporses (they likely expect a CLI binary), it's on them to check for php.exe.

The pain point is a lack of portability. There's a hardcoded value of "C:\php" for PHP_BINDIR.
And in C:\php I have an old version of Php for other purposes.
For Frankenphp I need to use the same version (8.5), the one that is bundled with Windows zip.
And also there's no way to change it "Constant PHP_BINDIR already defined, this will be an error in PHP 9".

[henderkes]

That is, once again, completely unrelated to FrankenPHP. Ask Amphp instead.

Amphp Parallel isn't actually parallel. It spawns a completely separate PHP process to run things and communicates through shared memory. If you install the parallel extension (which IIRC, is not compatible with windows), then it will spawn a separate thread and not need the separate process.

All that is from memory based on when I last used it 3-4 years ago. So it might be outdated.

Parallelism was always a pain in php. Some things work there, some require this and that.
Amphp Parallel serializes a tasks and submits to process (or thread).
