Instead of using a local installation of the PHP library, it’s possible to create a static build of FrankenPHP thanks to the great static-php-cli project (despite its name, this project support all SAPIs, not only CLI).
With this method, a single, portable, binary will contain the PHP interpreter, the Caddy web server and FrankenPHP!
We provide a Docker image to build a Linux static binary:
docker buildx bake --load static-builder
docker cp $(docker create --name static-builder dunglas/frankenphp:static-builder):/go/src/app/caddy/frankenphp/frankenphp frankenphp ; docker rm static-builder
The resulting static binary is named frankenphp and is available in the current directory.
If you want to build the static binary without Docker, take a look to the static-builder.Dockerfile file.
By default, most popular PHP extensions are compiled.
To reduce the size of the binary and to reduce the attack surface, you can choose the list of extensions to build using the PHP_EXTENSIONS Docker ARG.
For instance, run the following command to only build the opcache extension:
docker buildx bake --load --set static-builder.args.PHP_EXTENSIONS=opcache,pdo_sqlite static-builder
# ...
See the list of supported extensions.
If you hit the GitHub API rate limit, set a GitHub Personal Access Token in an environment variable named GITHUB_TOKEN:
GITHUB_TOKEN="xxx" docker --load buildx bake static-builder
# ...
Run the following command to create a static binary for macOS:
git clone --depth=1 https://github.com/crazywhalecc/static-php-cli.git
cd static-php-cli
composer install --no-dev -a
./bin/spc doctor --auto-fix
./bin/spc fetch --with-php=8.2 -A
./bin/spc build --enable-zts --build-embed --debug "bcmath,calendar,ctype,curl,dba,dom,exif,filter,fileinfo,gd,iconv,intl,mbstring,mbregex,mysqli,mysqlnd,opcache,openssl,pcntl,pdo,pdo_mysql,pdo_pgsql,pdo_sqlite,pgsql,phar,posix,readline,redis,session,simplexml,sockets,sqlite3,tokenizer,xml,xmlreader,xmlwriter,zip,zlib,apcu"
export CGO_CFLAGS="$(./buildroot/bin/php-config --includes | sed s#-I/#-I$PWD/buildroot/#g)"
export CGO_LDFLAGS="-framework CoreFoundation -framework SystemConfiguration $(./buildroot/bin/php-config --ldflags) $(./buildroot/bin/php-config --libs)"
git clone --depth=1 https://github.com/dunglas/frankenphp.git
