12-Factor App Compliance Check

Analyze PHP code for violations of the 12-Factor App methodology that hinder deployment, scalability, and operational excellence.

Detection Patterns

1. Hardcoded Configuration (Factor III: Config)

<?php

declare(strict_types=1);

// BAD: Configuration values embedded in source code
final class MailerConfig
{
    private string $smtpHost = 'smtp.gmail.com';
    private int $smtpPort = 587;
    private string $apiKey = 'sk-live-abc123xyz';
