# static-php-cli

Compile A Statically Linked PHP With Swoole and other Extensions.

Compile a purely static PHP binary file with various extensions to make PHP-cli applications more portable! 

You can also use the micro binary file to package PHP source code and binary files into one for distribution!
This function is provided by [dixyes/phpmicro](https://github.com/dixyes/phpmicro).

Note: only support cli, not support fpm, cgi.

> This branch is new version, if you are looking for old bash version of static-php-cli, see [bash-version](https://github.com/crazywhalecc/static-php-cli/tree/bash-version).

## Compilation Requirements

Yes, this project is written in PHP, pretty funny.
But php-static-cli runtime only requires an environment above PHP 8.0 and tokenizer extension.

- Linux
  - Supported arch: aarch64, amd64
  - Supported distributions: alpine, ubuntu, centos
  - Requirements: make, bison, flex, pkg-config, git, autoconf, automake, tar, unzip, gzip, bzip2, cmake
- macOS
  - Supported arch: arm64, x86_64
  - Requirements: make, bison, flex, pkg-config, git, autoconf, automake, tar, unzip, xz, gzip, bzip2, cmake
- Windows
  - Supported arch: x86_64
  - Requirements: (TODO)
- PHP
  - Supported compile version: 7.4, 8.0, 8.1, 8.2
  - Self required version: 8.0, 8.1, 8.2

## Usage

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

### Supported Extensions

[Support Extension List](/ext-support.md)

### GitHub Actions Build

Use GitHub Action to easily build a statically compiled PHP and phpmicro, 
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.

### Manual Build

```bash
# Clone first
git clone https://github.com/crazywhalecc/static-php-cli.git
cd static-php-cli
composer update
chmod +x bin/spc
# Check system tool dependencies, and show instructions for fixing (TODO)
# ./spc doctor
# fetch all libraries
./bin/spc fetch --all
# 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-all
```

You can also use the parameter `--with-php=x.y` to specify the downloaded PHP version, currently supports 7.4 ~ 8.2:

```bash
./bin/spc fetch --with-php=8.2 --all
```

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

```bash
./bin/spc build openssl --debug
./bin/spc fetch --all --debug
```

### php-cli Usage

> php-cli is a single static binary, which is similar with Go, Rust single-file binary.

When using the parameter `--build-all` or not adding the `--build-micro` parameter, 
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 `source/php-src/sapi/cli/`, simply copy it out for use.

```bash
./php -v
./php -m
./php your_code.php
```

### micro.sfx Usage

> phpmicro is a Self-Extracted Executable SAPI module, provided by [dixyes/phpmicro](https://github.com/dixyes/phpmicro). 
> This project is integrated with it.

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.

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

# If packing a PHAR file, simply replace code.php with the Phar file path.
```

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

## Current Status

- [X] Basic CLI framework (by `symfony/console`)
- [X] Linux support
- [X] macOS support
- [X] Exception handler
- [ ] Windows support
- [X] PHP 7.4 support

More functions and features are coming soon, Bugs and TODOs: https://github.com/crazywhalecc/static-php-cli/issues/32

## Contribution

Currently, there are only a few supported extensions. 
If the extension you need is missing, you can create an issue. 
If you are familiar with this project, you are also welcome to initiate a pull request.

The basic principles for contributing are as follows:

- This project uses php-cs-fixer and phpstan as code formatting tools. Before contributing, please run `composer analyze` and `composer cs-fix` on the updated code.
- If other open source libraries are involved, the corresponding licenses should be provided. 
    Also, configuration files should be sorted using the command `sort-config` after modification.
    For more information about sorting commands, see the documentation.
- Naming conventions should be followed, such as using the extension name registered in PHP for the extension name itself, 
    and external library names should follow the project's own naming conventions. For internal logic functions, class names, variables, etc., 
    camelCase and underscore formats should be followed, and mixing within the same module is prohibited.
- When compiling external libraries and creating patches, compatibility with different operating systems should be considered.

## Open-Source License

This project is based on the tradition of using the MIT License for old versions, 
while the new version references source code from some other projects:

- [dixyes/lwmbs](https://github.com/dixyes/lwmbs) (Mulun Permissive License)
- [swoole/swoole-cli](https://github.com/swoole/swoole-cli) (Apache 2.0 LICENSE+SWOOLE-CLI LICENSE)

Due to the special nature of this project, 
many other open source projects such as curl and protobuf will be used during the project compilation process, 
and they all have their own open source licenses.

Please use the `dump-license`(TODO) command to export the open source licenses used in the project after compilation, 
and comply with the corresponding project's LICENSE.

## Advanced

This project is pure open source project, and some modules are separated for developing.

This section will be improved after refactor version released.
