CLI Reference

::: tip If you installed spc as a pre-built binary, replace every spc in this page with ./spc (or .\spc.exe on Windows).

If you installed from source, use bin/spc instead. :::

build:php

Build PHP and extensions from source. Alias: build.

spc build:php <extensions> [options]

extensions (required): Comma-separated list of extensions to compile statically (e.g. "bcmath,openssl,curl").

All download options are also available on build:php with the --dl- prefix (e.g. --dl-with-php=8.3, --dl-parallel=4). These are passed to the automatic downloader that runs before the build.

SAPI Selection

These flags apply only to the combined build:php target. To build a specific SAPI in isolation, use its dedicated command (e.g. spc build:php-cli).

Option	Description
--build-cli	Build the cli SAPI (php / php.exe)
--build-fpm	Build php-fpm (Linux and macOS only)
--build-cgi	Build php-cgi
--build-micro	Build micro.sfx
--build-embed	Build the embed static library (libphp.a / php8embed.lib)
--build-frankenphp	Build the FrankenPHP binary

Common Build Options

Option	Short	Description
--no-strip		Keep debug symbols; do not strip the binary
--with-upx-pack		Compress the output binary with UPX (install first with spc install-pkg upx; Linux and Windows only)
--disable-opcache-jit		Disable OPcache JIT
--with-config-file-path=<path>		Directory where PHP looks for php.ini (default: /usr/local/etc/php)
--with-config-file-scan-dir=<path>		Directory PHP scans for additional .ini files (default: /usr/local/etc/php/conf.d)

--enable-zts		Enable thread-safe (ZTS) mode
--no-smoke-test		Skip the post-build smoke tests
--with-suggests		Also resolve and install suggested packages
--with-packages=<list>		Additional packages to install alongside the build
--no-download		Skip the download step (use existing cached files)
--build-shared=<list>	-D	Extensions to compile as shared .so / .dll instead of static

micro Options

Option	Description
--with-micro-fake-cli	Make micro's PHP_SAPI report cli instead of micro
--without-micro-ext-test	Disable the post-build extension test for micro.sfx
--with-micro-logo=<path>	Embed a custom .ico icon into micro.sfx (Windows only)
--enable-micro-win32	Build micro.sfx as a Win32 GUI application instead of a console app (Windows only)

frankenphp Options

Option	Description
--enable-zts	Required for FrankenPHP; enables thread-safe mode
--with-frankenphp-app=<path>	Embed a directory into the FrankenPHP binary

embed Options

Option	Description
--build-shared=<list>	Compile specific extensions as shared libraries (requires embed SAPI)
--maintainer-skip-build	(maintainer only) Skip the PHP embed build if libphp.a / libphp.so already exists in buildroot

Download Pass-through Options

All downloader options are available with the --dl- prefix:

Option	Description
--dl-with-php=<ver>	PHP version to download (default: 8.5)
--dl-prefer-binary	Prefer pre-built binaries for dependencies
--dl-parallel=<n>	Number of parallel downloads
--dl-retry=<n>	Number of retries on failure
--dl-custom-url=<src:url>	Override a source download URL
--dl-custom-git=<src:branch:url>	Override with a custom git repository

Downloader options passed to build:php are used by the automatic downloader that runs before the build. This allows you to control the download behavior without needing a separate spc download command.

spc build:php "bcmath,openssl,curl" --build-cli --dl-with-php=8.3 --dl-prefer-binary --dl-parallel=4

Examples

# Build cli SAPI
spc build:php "bcmath,openssl,curl" --build-cli

# Build cli + micro together
spc build:php "bcmath,phar,openssl,curl" --build-cli --build-micro

# Build with a specific PHP version
spc build:php "bcmath,openssl" --build-cli --dl-with-php=8.3

# Bake INI into the binary
spc build:php "bcmath,pcntl" --build-cli -I "memory_limit=4G" -I "disable_functions=system"

# Keep debug symbols
spc build:php "bcmath,openssl" --build-cli --no-strip

# Build FrankenPHP (ZTS required)
