README

Latest Version on Packagist Total Downloads

PHP wrapper for Claude Code. Fun fact: This SDK was built by using Claude Code to port its own Python SDK to PHP. 🤖

Stream Claude's responses, track token usage, hook into events, and integrate AI coding assistance into your PHP apps.

Installation

composer require purewater2011/claude-code-sdk

Make sure Claude Code CLI is installed:

npm install -g @anthropic-ai/claude-code

PHP 7.4+ Compatibility

This SDK is fully compatible with PHP 7.4 and higher using modern PHP patterns:

Key Features

Fluent Interface - Chain methods for clean configuration:

$options = Options::create()
    ->systemPrompt('You are a helpful assistant')
    ->allowedTools(['Read', 'Write'])
    ->maxTurns(5);

PermissionMode - Use static methods:

PermissionMode::default()       // Default permission mode
PermissionMode::acceptEdits()   // Auto-accept edits
PermissionMode::bypassPermissions()  // Bypass all permission checks

MCP Server Config - Easy server configuration:

MCPServerConfig::stdio('node', ['server.js'])
MCPServerConfig::sse('https://api.example.com/sse')
MCPServerConfig::http('https://api.example.com/mcp')

Note: All examples in this README use the fluent interface pattern, which is the recommended approach for PHP 7.4+. See PHP74_MIGRATION.md for detailed compatibility information.

Quick Start

Basic Usage

<?php

use Purewater2011\ClaudeCode\ClaudeCode;
use Purewater2011\ClaudeCode\Types\Messages\AssistantMessage;
use Purewater2011\ClaudeCode\Types\Messages\SystemMessage;
use Purewater2011\ClaudeCode\Types\Messages\ResultMessage;
use Purewater2011\ClaudeCode\Types\ContentBlocks\TextBlock;

// Send a query to Claude
$messages = ClaudeCode::query("What files are in the current directory?");

// Process the streaming response
foreach ($messages as $message) {
    if ($message instanceof SystemMessage) {
        echo "[SYSTEM] {$message->subtype}\n";
    } elseif ($message instanceof AssistantMessage) {
        foreach ($message->content as $block) {
            if ($block instanceof TextBlock) {
                echo "[CLAUDE] {$block->text}\n";
            }
        }
    } elseif ($message instanceof ResultMessage) {
        echo "[DONE] Cost: \${$message->totalCostUsd} | Time: {$message->durationMs}ms\n";
    }
}

With Options

use Purewater2011\ClaudeCode\ClaudeCode;
use Purewater2011\ClaudeCode\Types\Config\Options;
use Purewater2011\ClaudeCode\Types\Enums\PermissionMode;

// Create options using fluent interface
$options = Options::create()
    ->systemPrompt('You are a helpful coding assistant')
    ->allowedTools(['Read', 'Write', 'Edit'])
    ->permissionMode(PermissionMode::acceptEdits())
    ->maxTurns(5);

/**
 * A generator is returned, allowing you to stream messages as they are generated.
 * @var Generator<Purewater2011\ClaudeCode\Types\Messages\Message> $messages
 */
$messages = ClaudeCode::query("Help me refactor this code", $options);

foreach ($messages as $message) {
    if ($message instanceof AssistantMessage) {
        foreach ($message->content as $block) {
            if ($block instanceof TextBlock) {
                echo "[CLAUDE] {$block->text}\n";
            }
        }
    } elseif ($message instanceof ResultMessage) {
        echo "[DONE] Total Cost: \${$message->totalCostUsd}\n";
    }
}

Usage in Laravel

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=claude-code-config

Configure your settings in config/claude-code.php or use environment variables:

CLAUDE_CODE_SYSTEM_PROMPT="You are a Laravel expert"
CLAUDE_CODE_ALLOWED_TOOLS=Read,Write,Edit
CLAUDE_CODE_PERMISSION_MODE=acceptEdits
CLAUDE_CODE_MODEL=claude-3-sonnet

Using the Facade

use Purewater2011\ClaudeCode\Laravel\Facades\ClaudeCode;

// Simple query
$messages = ClaudeCode::query("Create a new Laravel controller");

// With custom options
$options = ClaudeCode::options()
    ->systemPrompt("You are a Laravel expert")
    ->allowedTools(['Read', 'Write', 'Edit'])
    ->maxTurns(10);

$messages = ClaudeCode::query("Help me build a REST API", $options);

Dependency Injection

use Illuminate\Support\Facades\App;

class MyService
{
    private $claude;
    
    public function __construct()
    {
        $this->claude = App::make('claude-code');
    }

    public function generateCode(string $prompt): void
    {
        $messages = $this->claude->query($prompt);
        
        foreach ($messages as $message) {
            // Process messages...
        }
    }
}

## Message Types

The SDK provides strongly-typed message classes with proper DTOs:

### SystemMessage

System events with typed data for initialization:

```php
use Purewater2011\ClaudeCode\Types\Messages\SystemMessage;
use Purewater2011\ClaudeCode\Types\Config\SystemInitData;

if ($message instanceof SystemMessage && $message->subtype === 'init') {
    // Strongly typed init data
    $initData = $message->data; // SystemInitData instance
    echo "Session ID: {$initData->sessionId}\n";
    echo "Model: {$initData->model}\n";
    echo "Tools: " . implode(', ', $initData->tools) . "\n";
    echo "Working Directory: {$initData->cwd}\n";
}

AssistantMessage

Contains content blocks with Claude's responses:

use Purewater2011\ClaudeCode\Types\Messages\AssistantMessage;
use Purewater2011\ClaudeCode\Types\ContentBlocks\TextBlock;
use Purewater2011\ClaudeCode\Types\ContentBlocks\ToolUseBlock;
use Purewater2011\ClaudeCode\Types\ContentBlocks\ToolResultBlock;

foreach ($message->content as $block) {
    if ($block instanceof TextBlock) {
        echo "Text: {$block->text}\n";
    } elseif ($block instanceof ToolUseBlock) {
        echo "Tool: {$block->name} with " . json_encode($block->input) . "\n";
    } elseif ($block instanceof ToolResultBlock) {
        echo "Result: {$block->content} (Error: " . ($block->isError ? 'Yes' : 'No') . ")\n";
    }
}

UserMessage

User input and tool feedback:

use Purewater2011\ClaudeCode\Types\Messages\UserMessage;
use Purewater2011\ClaudeCode\Types\ContentBlocks\ToolResultBlock;

// Simple text message
$message = new UserMessage("Hello Claude!");

// Tool feedback (from Claude's perspective)
if (is_array($message->content)) {
    foreach ($message->content as $block) {
        if ($block instanceof ToolResultBlock) {
            echo "Tool feedback: {$block->content}\n";
            echo "Tool ID: {$block->toolUseId}\n";
            echo "Is Error: " . ($block->isError ? 'Yes' : 'No') . "\n";
        }
    }
}

ResultMessage

Session completion with usage metrics:

use Purewater2011\ClaudeCode\Types\Messages\ResultMessage;

echo "Total Cost: \${$message->totalCostUsd}\n";
echo "Duration: {$message->durationMs}ms\n";
echo "API Time: {$message->durationApiMs}ms\n";
echo "Turns: {$message->numTurns}\n";
echo "Session ID: {$message->sessionId}\n";
echo "Input Tokens: {$message->usage['input_tokens']}\n";
echo "Output Tokens: {$message->usage['output_tokens']}\n";

MCP Server Configuration

Configure Model Context Protocol servers:

use Purewater2011\ClaudeCode\Types\Config\Options;
use Purewater2011\ClaudeCode\Types\Config\MCPServerConfig;

$options = Options::create()
    ->mcpServers([
        // Stdio server
        'filesystem' => MCPServerConfig::stdio(
            'node',
            ['mcp-server-filesystem.js'],
            ['NODE_ENV' => 'production']
        ),

        // SSE server
        'weather' => MCPServerConfig::sse(
            'https://api.example.com/mcp/sse',
            ['Authorization' => 'Bearer token']
        ),

        // HTTP server
        'database' => MCPServerConfig::http(
            'https://api.example.com/mcp',
            ['API-Key' => 'secret']
        )
    ]);

MCP Server Types:

// Stdio server (local process)
MCPServerConfig::stdio(
    'node',                              // command
    ['server.js'],                       // args
    ['NODE_ENV' => 'production']         // env (optional)
);

// SSE server (server-sent events)
MCPServerConfig::sse(
    'https://api.example.com/sse',       // url
    ['Authorization' => 'Bearer token']  // headers (optional)
);

// HTTP server
MCPServerConfig::http(
    'https://api.example.com/mcp',       // url
    ['API-Key' => 'secret']              // headers (optional)
);

Interceptors

Note: This is NOT related to or the same as Claude Code Hooks

The SDK supports interceptors that allow you to tap into various events during the Claude Code lifecycle. This is useful for logging, monitoring, debugging, or building real-time UI updates.

Available Hook Points

  • onQueryStart - Fired when a query begins
  • onRawMessage - Fired when raw JSON is received from Claude Code CLI
  • onMessageParsed - Fired after a message is parsed into a typed object
  • onQueryComplete - Fired when the query completes successfully
  • onError - Fired when an error occurs

Basic Usage

use Purewater2011\ClaudeCode\ClaudeCode;
use Purewater2011\ClaudeCode\Types\Config\Options;

// Simple logging interceptor
$logger = function($event, $data) {
    echo "[{$event}] " . json_encode($data) . PHP_EOL;
};

$options = Options::create()
    ->interceptors([$logger]);

$messages = ClaudeCode::query("Help me code", $options);

Example Interceptors

File Logger

use Purewater2011\ClaudeCode\Examples\Interceptors\FileLoggerInterceptor;

$options = Options::create()
    ->interceptors([
        new FileLoggerInterceptor('/tmp/claude.log')
    ]);

Metrics Collector

use Purewater2011\ClaudeCode\Examples\Interceptors\MetricsInterceptor;

$options = Options::create()
    ->interceptors([
        new MetricsInterceptor() // Tracks token usage, costs, and timing
    ]);

Webhook Dispatcher

use Purewater2011\ClaudeCode\Examples\Interceptors\WebhookInterceptor;

$options = Options::create()
    ->interceptors([
        new WebhookInterceptor('https://api.example.com/claude-events')
    ]);

Custom Interceptor

// Token usage tracker
$totalTokens = 0;
$tokenTracker = function($event, $data) use (&$totalTokens) {
    if ($event === 'onMessageParsed' && $data['message'] instanceof ResultMessage) {
        $totalTokens += $data['message']->usage['input_tokens'] ?? 0;
        $totalTokens += $data['message']->usage['output_tokens'] ?? 0;
    }
};

// Real-time progress indicator
$progressTracker = function($event, $data) {
    switch ($event) {
        case 'onQueryStart':
            echo "Starting query: {$data['prompt']}\n";
            break;
        case 'onMessageParsed':
            echo "."; // Progress dot for each message
            break;
        case 'onQueryComplete':
            echo "\nQuery completed!\n";
            break;
    }
};

$options = Options::create()
    ->interceptors([$tokenTracker, $progressTracker]);

Laravel Integration

// In a service provider
$this->app->bind(Options::class, function ($app) {
    $interceptors = [];

    // Add logging if enabled
    if (config('claude-code.logging.enabled')) {
        $interceptors[] = new FileLoggerInterceptor(
            storage_path('logs/claude-code.log')
        );
    }

    // Add metrics collection
    if (config('claude-code.metrics.enabled')) {
        $interceptors[] = new MetricsInterceptor();
    }

    return Options::create()
        ->interceptors($interceptors)
        ->systemPrompt(config('claude-code.system_prompt'))
        ->model(config('claude-code.model'));
});

Error Handling

The SDK provides specific exception types for different failure scenarios:

use Purewater2011\ClaudeCode\ClaudeCode;
use Purewater2011\ClaudeCode\Exceptions\CLINotFoundException;
use Purewater2011\ClaudeCode\Exceptions\CLIConnectionException;
use Purewater2011\ClaudeCode\Exceptions\ProcessException;

try {
    $messages = ClaudeCode::query("Help me code");
} catch (CLINotFoundException $e) {
    echo "Claude Code CLI not found. Install with: npm install -g @anthropic-ai/claude-code";
} catch (CLIConnectionException $e) {
    echo "Failed to connect to Claude Code: {$e->getMessage()}";
} catch (ProcessException $e) {
    echo "Process failed with exit code {$e->exitCode}: {$e->stderr}";
}
