PHP-OS

The PHP-OS is implemented an Operating System written in PHP. This is not an emulator for architectures; for example. i386, x86_64 and so on. This project makes an assembly or image file directly for an operating system.

Moreover, this is very ultra hyper maximum experimental implementation.

Requirements

• PHP 8.3+
• qemu
• nasm
• make

Notice

In currently status, this project only implements Intel x86_64 architecture. But you can try this architecture with using QEMU on aarch (macOS M1, M2).

Quick Start

1. Install PHP-OS via composer.

$ composer require m3m0r7/php-os

2. Write an example code as HelloWorld.php as following.

<?php

require __DIR__ . '/vendor/autoload.php';

$bootloader = new \PHPOS\OS\Code(
    new \PHPOS\Architecture\Architecture(
    // Use x86_64 architecture
        \PHPOS\Architecture\ArchitectureType::x86_64,
    ),
);

// Initialize bootloader
$bootloader
    // Set 16 bit real mode
    ->setBits(\PHPOS\OS\BitType::BIT_16)

    // Set bootloader origin
    ->setOrigin(\PHPOS\OS\OSInfo::MBR)

    // Print Hello World into BIOS screen
    ->registerService(\PHPOS\Service\Kit\Startup\HelloWorld::class)

    // Add bootloader signature
    ->registerPostService(\PHPOS\Service\BIOS\Bootloader\BootloaderSignature::class);

// Bundle the code into an OS image
$bundler = new \PHPOS\OS\Bundler\Bundler(
    new \PHPOS\OS\ConfigureOption(
        __DIR__ . '/dist',
        'php-os.img',
        $bootloader,
    ),
);

// Distribute Makefile and assembly into `dist` directory by the ConfigureOption
$bundler->distribute();

3. Make with NASM instructions and build an OS image as following.

$ cd dist && make clean && make all

4. Start QEMU with qemu command as following.

$ qemu-system-x86_64 -drive file=./dist/build/php-os.img,format=raw

5. Show figure as following if you successfully to run the QEMU.

The quick start example will generate an assembly file as following:

;
;   _______  ____  ____  _______            ___     ______
;  |_   __ \|_   ||   _||_   __ \         .'   `. .' ____ \
;    | |__) | | |__| |    | |__) |______ /  .-.  \| (___ \_|
;    |  ___/  |  __  |    |  ___/|______|| |   | | _.____`.
;   _| |_    _| |  | |_  _| |_           \  `-'  /| \____) |
;  |_____|  |____||____||_____|           `.___.'  \______.'
