With Composer

The plugin fetches it, the lock pins it.

composer require phaenon/phn installs a plugin that downloads the binary for the running platform through Composer's own HTTP client, checks it against the SHA-256 the package pins, keeps it in Composer's cache and links it as vendor/bin/phn. Because composer.lock pins the package, it pins the compiler.

binary-url in the project's composer.json names where the files come from, with {version} and {file} filled in by the plugin: this site, or a mirror of it with the same file names.

PHN_BINARY=/path/to/phn replaces the download with another binary, such as one built from a checkout.
