This builds V8 and php-v8js on Ubuntu 20.04 Focal, 22.04 Jammy and 24.04 Noble, depending which docker image you use .
Modify the versions to your needs in build.sh:
LIBV8_BUILD_VERSIONS
PHP_VERSION
PHP_V8JS_REPO
PHP_V8JS_REPO_COMMIT
PHP_V8JS_VERSION
There might be more recent forks of v8js repo: https://github.com/phpv8/v8js/forks . There's a convenient page showing how many commits ahead or behind the forks are from the base repo : https://useful-forks.github.io/?repo=phpv8/v8js . You need to add your Github Account access token to the page (upper right corner) as Github rate-limits anonymous API requests.
This will mount the current path. All files are going to be created inside folder build.
With using --rm the container and all it's content (but not the mounted current path) will be removed after you exit.
