Python-in-PHP

The Python-in-PHP library allows you to easily use any Python packages as if they were native PHP packages 🐘

🔥 Fully use artificial intelligence frameworks for AI models inference or training directly in PHP!
You can run AI models with libraries like transformers, torch, vllm, numpy, etc. in your PHP project with PHP syntax.

✅ Environment with Python is installed automatically with Composer.

✅ Any Python packages are installed via Composer with a built-in package manager.

✅ Automatic PHPDoc generation for code completion in IDEs for any Python packages.

Installation

composer require syncfly/python-in-php

You need to answer "yes" when prompted to activate the plugin.

Documentation

You can find the documentation here: (coming soon)

Package manager

The Python-in-PHP Package Manager is a built-in package manager based on uv that allows you to install and manage Python packages.

Intsall a package

composer pip install <package-name>

Uninstall a package

composer pip uninstall <package-name>

Upgrade a package

composer pip install --upgrade <package-name>

Examples

Look at an example of using transformers and torch in PHP for running an AI model:

<?php

use py\transformers;
use py\torch;

$model_name = 'google/gemma-3-4b-it';

$tokenizer = transformers\AutoTokenizer::from_pretrained($model_name);

$model = transformers\AutoModelForCausalLM::from_pretrained(
    $model_name,
    torch_dtype: torch::$bfloat16,
    device_map: "auto"
);

$messages = [
    ['role' => 'user', 'content' => 'Why PHP is great?']
];

$input_ids = $tokenizer->apply_chat_template(
    $messages,
    return_tensors: 'pt',
    add_generation_prompt: true
);

$outputs = $model->generate(
    $input_ids,
    max_new_tokens: 2048
);

$result = $tokenizer->decode($outputs[0], skip_special_tokens: true);

Or simplier with transformers pipeline:

<?php

use py\transformers;

$pipe = transformers\pipeline(
    'text-generation',
    model: 'google/gemma-3-4b-it',
    torch_dtype: torch::$bfloat16,
    device_map: 'auto'
);

$messages = [
    ['role' => 'user', 'content' => 'Why PHP is great?']
];

$output = $pipe($messages, max_new_tokens: 2048);
$generated = $output[0]['generated_text'];
$result = end($generated)['content'];
