This document explains how to create a FrankenPHP binary that will load PHP as a dynamic library. This is the recommended method.
Alternatively, static builds can also be created.
FrankenPHP is compatible with PHP 8.2 and superior.
First, get the PHP sources and extract them:
tar xf php-*
cd php-*/Then, run the configure script with the options needed for your platform.
The following ./configure flags are mandatory, but you can add others, for example, to compile extensions or additional features.
./configure \
--enable-embed \
--enable-zts \
--disable-zend-signals \
--enable-zend-max-execution-timersUse the Homebrew package manager to install
libiconv, bison, re2c and pkg-config:
brew install libiconv bison brotli re2c pkg-config
echo 'export PATH="/opt/homebrew/opt/bison/bin:$PATH"' >> ~/.zshrcThen run the configure script:
./configure \
--enable-embed=static \
--enable-zts \
--disable-zend-signals \
--disable-opcache-jit \
--enable-static \
--enable-shared=no \
--with-iconv=/opt/homebrew/opt/libiconv/Finally, compile and install PHP:
make -j"$(getconf _NPROCESSORS_ONLN)"
sudo make installSome FrankenPHP features depend on optional system dependencies that must be installed. Alternatively, these features can be disabled by passing build tags to the Go compiler.
| Feature | Dependency | Build tag to disable it |
|---|---|---|
| Brotli compression | Brotli | nobrotli |
| Restart workers on file change | Watcher C | nowatcher |
You can now build the final binary:
curl -L https://github.com/dunglas/frankenphp/archive/refs/heads/main.tar.gz | tar xz
cd frankenphp-main/caddy/frankenphp
CGO_CFLAGS=$(php-config --includes) CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" go build -tags=nobadger,nomysql,nopgxAlternatively, use xcaddy to compile FrankenPHP with custom Caddy modules:
CGO_ENABLED=1 \
XCADDY_GO_BUILD_FLAGS="-ldflags='-w -s' -tags=nobadger,nomysql,nopgx" \
CGO_CFLAGS=$(php-config --includes) \
CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
xcaddy build \
--output frankenphp \
--with github.com/dunglas/frankenphp/caddy \
--with github.com/dunglas/mercure/caddy \
--with github.com/dunglas/vulcain/caddy
# Add extra Caddy modules hereTip
If you're using musl libc (the default on Alpine Linux) and Symfony,
you may need to increase the default stack size.
Otherwise, you may get errors like PHP Fatal error: Maximum call stack size of 83360 bytes reached during compilation. Try splitting expression
To do so, change the XCADDY_GO_BUILD_FLAGS environment variable to something like
XCADDY_GO_BUILD_FLAGS=$'-ldflags "-w -s -extldflags \'-Wl,-z,stack-size=0x80000\'"'
(change the stack size value according to your app needs).
