doppel-sdk — PHP
================

[](#doppel-sdk--php)

Official Doppel SDK for PHP. Capture your LLM calls and forward them to Doppel.

> **Note:** like the Java SDK, PHP captures each call explicitly with a small fluent builder right after you make it (PHP can't transparently monkey-patch a client). No required runtime dependencies beyond ext-curl / ext-json.

- **Package:** `doppelimpacttest/doppel-sdk`
- **PHP:** 8.1+

Install
-------

[](#install)

```
composer require doppelimpacttest/doppel-sdk
```

Usage
-----

[](#usage)

```
use Doppel\DoppelClient;

$doppel = new DoppelClient(shadowModel: 'gpt-4o-mini'); // reads DOPPEL_API_KEY

// ... make your OpenAI call, then capture it:
$doppel->openAI()
    ->model('gpt-4o')
    ->messages($messages)                 // array of message maps
    ->answer($answer)
    ->promptTokens(10)->completionTokens(5)->totalTokens(15)
    ->durationMs($elapsedMs)
    ->capture();
```

Other providers:

```
$doppel->anthropic()->model('claude-...')->prompt($prompt)->answer($out)
    ->promptTokens(8)->completionTokens(4)->durationMs($ms)->capture();

$doppel->google()->model('gemini-...')->prompt($prompt)->answer($out)
    ->promptTokens(5)->completionTokens(3)->durationMs($ms)->capture();

$doppel->openRouter()->model('anthropic/claude-3.5-sonnet')->messages($messages)
    ->answer($out)->vendor('anthropic')->cost(0.00021)->totalTokens(15)->durationMs($ms)->capture();
```

Capture never throws into your request path.

Publishing
----------

[](#publishing)

This package is published via subtree-split: pushing a `php-v*` tag splits `sdks/php` into the `doppelimpacttest/doppel-php` repo as a `vX.Y.Z` tag, which Packagist tracks and publishes.

```
# bump version in the consuming repo's tag, then:
git tag php-v0.1.0
git push origin php-v0.1.0
```
