This SAPI feature is from the Fork of dixyes/phpmicro.

Direct Download

If you don't want to compile yourself, you can download example pre-compiled artifact from Actions, or from self-hosted server.

self-hosted server contains extensions: bcmath,bz2,calendar,ctype,curl,dom,exif,fileinfo,filter,ftp,gd,gmp,iconv,xml,mbstring,mbregex,mysqlnd,openssl,pcntl,pdo,pdo_mysql,pdo_sqlite,phar,posix,redis,session,simplexml,soap,sockets,sqlite3,tokenizer,xmlwriter,xmlreader,zlib,zip

Compilation Requirements

Yes, this project is written in PHP, pretty funny. But static-php-cli runtime only requires an environment above PHP 8.1 and mbstring, pcntl extension.

Here is the architecture support status, where :octocat: represents support for GitHub Action builds, 💻 represents support for local manual builds, and blank represents not currently supported.

x86_64 aarch64
macOS :octocat: 💻 💻
Linux :octocat: 💻 :octocat: 💻
FreeBSD 💻 💻

macOS-arm64 is not supported for GitHub Actions, if you are going to build on arm, you can build it manually on your own machine.

Currently supported PHP versions for compilation are: 7.3, 7.4, 8.0, 8.1, 8.2, 8.3.

Supported Extensions

Please first select the extension you want to compile based on the extension list below.

If an extension you need is missing, you can submit an issue.

Here is the current planned roadmap for extension support: #152 .

GitHub Actions Build

Use GitHub Action to easily build a statically compiled PHP, and at the same time define the extensions to be compiled by yourself.

  1. Fork me.
  2. Go to the Actions of the project and select CI.
  3. Select Run workflow, fill in the PHP version you want to compile, the target type, and the list of extensions. (extensions comma separated, e.g. bcmath,curl,mbstring)
  4. After waiting for about a period of time, enter the corresponding task and get Artifacts.

If you enable debug, all logs will be output at build time, including compiled logs, for troubleshooting.

  • When using ubuntu-latest, it will build linux-x86_64 binary.
  • When using macos-latest, it will build macOS-x86_64 binary.

Manual build (using SPC binary)

This project provides a binary file of static-php-cli. You can directly download the binary file of the corresponding platform and then use it to build static PHP. Currently, the platforms supported by spc binary are Linux and macOS.

Here's how to download from GitHub Actions:

  1. Enter GitHub Actions or self-hosted nightly builds.
  2. If you download from GHA, select the latest build task, select Artifacts, and download the binary file of the corresponding platform.
  3. If you download from GHA, unzip the .zip file. After decompressing, add execution permissions to it: chmod +x ./spc.
  4. If you download from self-hosted server, download spc-$os-$arch file and just use it (don't forget chmod +x).

SPC single-file binary is built by phpmicro and box, and it doesn't need to install PHP. Just treat spc as a standalone executable.

Manual build (using source code)

Clone repo first:

git clone

If you have not installed php on your system, you can use package management to install PHP (such as brew, apt, yum, apk etc.).

And you can also download single-file php binary and composer using command bin/setup-runtime. The PHP runtime for static-php-cli itself will be downloaded at bin/php, and composer is at bin/composer.

cd static-php-cli
chmod +x bin/setup-runtime
# It will download php-cli from self-hosted server and composer from

# Use this php runtime to run static-php-cli compiler
./bin/php bin/spc

# Use composer
./bin/php bin/composer

# Initialize this project
cd static-php-cli
composer update
chmod +x bin/spc

Use static-php-cli

Basic usage for building php and micro with some extensions:

If you are using the packaged spc binary, you need to replace bin/spc with ./spc in the following commands.

# Check system tool dependencies, fix them automatically
./bin/spc doctor
# fetch all libraries
./bin/spc download --all
# only fetch necessary sources by needed extensions
./bin/spc download --for-extensions=openssl,pcntl,mbstring,pdo_sqlite
# with bcmath,openssl,tokenizer,sqlite3,pdo_sqlite,ftp,curl extension, build both CLI and phpmicro SAPI
./bin/spc build bcmath,openssl,tokenizer,sqlite3,pdo_sqlite,ftp,curl --build-cli --build-micro

You can also use the parameter --with-php=x.y to specify the downloaded PHP version, currently supports 7.4 ~ 8.3:

# Using PHP >= 8.0 is recommended, because PHP7 cannot use phpmicro
./bin/spc fetch --with-php=8.2 --all

Now we support cli, micro, fpm, you can use one or more of the following parameters to specify the compiled SAPI:

  • --build-cli: build static cli executable
  • --build-micro: build static phpmicro self-extracted executable
  • --build-fpm: build static fpm binary
  • --build-embed: build embed (libphp)
  • --build-all: build all

If anything goes wrong, use --debug option to display full terminal output:

./bin/spc build openssl,pcntl,mbstring --debug --build-all
./bin/spc fetch --all --debug

In addition, we build NTS by default. If you are going to build ZTS version, just add --enable-zts option.

./bin/spc build openssl,pcntl --build-all --enable-zts

Adding option --no-strip can produce binaries with debug symbols, in order to debug (using gdb). Disabling strip will increase the size of static binary.

Different SAPI Usage

Use cli

php-cli is a single static binary, you can use it like normal php installed on your system.

When using the parameter --build-cli or --build-all, the final compilation result will output a binary file named ./php, which can be distributed and used directly. This file will be located in the directory buildroot/bin/, copy it out for use.

cd buildroot/bin/
./php -v                # check version
./php -m                # check extensions
./php your_code.php     # run your php code
./php your_project.phar # run your phar (project archive)

Use micro

phpmicro is a SelF-extracted eXecutable SAPI module, provided by phpmicro project. But this project is using a fork of phpmicro, because we need to add some features to it. It can put php runtime and your source code together.

When using the parameter --build-all or --build-micro, the final compilation result will output a file named ./micro.sfx, which needs to be used with your PHP source code like code.php. This file will be located in the path buildroot/bin/micro.sfx, simply copy it out for use.

Prepare your project source code, which can be a single PHP file or a Phar file, for use.

echo "<?php echo 'Hello world' . PHP_EOL;" > code.php
cat micro.sfx code.php > single-app && chmod +x single-app

If you package a PHAR file, just replace code.php with the phar file path. You can use box-project/box to package your CLI project as Phar, It is then combined with phpmicro to produce a standalone executable binary.

# Use the micro.sfx generated by static-php-cli to combine,
bin/spc micro:combine my-app.phar
# or you can directly use the cat command to combine them.
cat buildroot/bin/micro.sfx my-app.phar > my-app && chmod +x my-app

# Use micro:combine combination to inject INI options into the binary.
bin/spc micro:combine my-app.phar -I "memory_limit=4G" -I "disable_functions=system" --output my-app-2

In some cases, PHAR files may not run in a micro environment.

Use fpm

When using the parameter --build-all or --build-fpm, the final compilation result will output a file named ./php-fpm, This file will be located in the path buildroot/bin/, simply copy it out for use.

In normal Linux distributions and macOS systems, the package manager will automatically generate a default fpm configuration file after installing php-fpm. Because php-fpm must specify a configuration file before running, the php-fpm compiled by this project will not have any configuration files, so you need to write php-fpm.conf and pool.conf configuration files yourself.

Specifying php-fpm.conf can use the command parameter -y, for example: ./php-fpm -y php-fpm.conf.

Use embed

When using the project parameters --build-embed or --build-all, the final compilation result will output a libphp.a, php-config and a series of header files, stored in buildroot/. You can introduce them in your other projects.

If you know embed SAPI, you should know how to use it. You may require the introduction of other libraries during compilation, you can use buildroot/bin/php-config to obtain the compile-time configuration.

For an advanced example of how to use this feature, take a look at how to use it to build a static version of FrankenPHP.
