Phase 2: PHP Agentic Framework - Production Implementation

Overview

Complete production-ready implementation of the PHP agentic framework with all features fully implemented, based on Phase 1 skeleton.

Core Implementations

1. Enhanced Base Agent (src/Core/Agent.php)

<?php
namespace App\Core;

use App\Utils\Logger;
use App\Services\ModelProviderFactory;

abstract class Agent {
    protected string $name;
    protected string $model;
    protected array $context = [];
    protected ModelProvider $modelProvider;
    protected array $tools = [];
    protected Logger $logger;
    
    public function __construct(string $name, string $model) {
        $this->name = $name;
        $this->model = $model;
        $this->logger = new Logger($name);
        $this->modelProvider = ModelProviderFactory::create($model);
        $this->initializeTools();
    }
    
    abstract public function execute(array $input): array;
    
    protected function makeDecision(array $context): array {
        $prompt = $this->buildDecisionPrompt($context);
        
        $response = $this->modelProvider->generateResponse([
            'messages' => [
                ['role' => 'system', 'content' => $this->getSystemPrompt()],
                ['role' => 'user', 'content' => $prompt]
            ],
            'temperature' => 0.7,
            'max_tokens' => $this->model === 'gpt-4.1-mini' ? 10000 : 4000,
            'response_format' => ['type' => 'json_object']
        ]);
        
        return json_decode($response['content'], true);
    }
    
    protected function executeTools(array $toolCalls): array {
        $results = [];
        foreach ($toolCalls as $call) {
            if (isset($this->tools[$call['name']])) {
                $results[] = $this->tools[$call['name']]->execute($call['parameters']);
            }
