README

FullCrawl is a high-performance, framework-agnostic database migration system for PHP. It follows a "Zero Configuration" philosophy by inheriting your project's existing PDO connection, ensuring atomic operations through native database transactions.

Why FullCrawl?

Most migration systems force you to re-configure database credentials or bind you to a specific framework's ORM. FullCrawl breaks this cycle:

• Zero-Config: It uses the connection you already established.
• Atomic Operations: Every migration batch is wrapped in a transaction. If one fails, they all roll back.
• Framework Agnostic: Use it with Rubik, Slim, Lumen, WordPress, or your own custom-built engine.
• True Injection: No global states. The $pdo instance is injected directly into your migration closures.

Quick Start

1. Installation

composer require AdaiasMagdiel/FullCrawl

2. The Hook (fullcrawl.php)

Create a file named fullcrawl.php in your project root. It must return your active PDO instance.

<?php
// fullcrawl.php

require_once __DIR__ . '/vendor/autoload.php';

// Return your existing PDO instance from your Service Container, 
// Singleton, or Connection factory.
return \App\Core\Database::getInstance()->getConnection();

Usage

Command Line Interface

FullCrawl provides a powerful CLI to manage your database schema:

Anatomy of a Migration

When you run fullcrawl --new, a file is created in database/migrations/. You have full access to the $pdo object:

<?php

/**
 * FullCrawl Migration: create_users_table
 */
return [
    'up' => function(PDO $pdo) {
        $pdo->exec("CREATE TABLE users (
            id INT AUTO_INCREMENT PRIMARY KEY,
            username VARCHAR(50) NOT NULL,
            email VARCHAR(255) NOT NULL UNIQUE
        ) ENGINE=InnoDB");
    },
    'down' => function(PDO $pdo) {
        $pdo->exec("DROP TABLE users");
    }
];
