✨ Axpecto — A Modern PHP Meta-Framework

Axpecto is a powerful meta-framework for modern PHP development. It blends Aspect-Oriented Programming (AOP), dependency injection (DI), and enhanced collections, into a highly composable and extensible architecture designed for AI-augmented development.

With Axpecto, you can:

• Build flexible, modular frameworks (e.g., WordPress dev kits, internal platforms).
• Inject behavior into code using clean, declarative annotations.
• Autowire dependencies, inject properties, and intercept method calls without boilerplate.
• Work with expressive Kotlin-style collections in a PHP-native way.

⚙️ Axpecto is designed not just for developers, but for AI agents to extend, understand, and modify code easily, safely and cost efficiently.

📦 Installation

Install via Composer:

composer require rcrdortiz/axpecto

🚀 Quickstart

🔁 Functional Collections

Use Axpecto's Klist and Kmap for expressive list handling:

require_once 'src/functions.php';

$list = listOf(1, 2, 3, 4, 5);

$filtered = $list
    ->map(fn($i) => $i * 2)
    ->filter(fn($i) => $i > 5)
    ->toArray(); // [6, 8, 10]

Collections are immutable by default, but can be made mutable with $list->toMutable().

Real-World Example: Extract and format user names

class User {
    public function __construct(
        public readonly int $id,
        public readonly string $name
    ) {}
}

// Assume this is a list of User objects fetched from the user repository
$users = listOf(
    new User(1, 'Alice'),
    new User(2, 'Bob'),
    new User(3, 'Charlie')
);

$names = $users
    ->map(fn($u) => $u->name)
    ->join(', ');

// "Alice, Bob, Charlie"

Real-World Example: Group and filter by condition

$orders = listOf(150, 20, 35, 80, 200);

$highValueOrders = $orders
    ->filter(fn($amount) => $amount >= 100);

// [150, 200]

Real-World Example: Using maybe to conditionally perform a context aware action

$logs = listOf('info', 'debug', 'error');

// maybe() allows optional side effects or context-aware logic only when the list contains items
$logs->maybe(function(Klist $items) {
    $logger->log($items);
    $stats->bump('logs', $items->count());
    echo "done logging " . $items->count() . " items";
});

// done logging 3 items

// Now, let's say we have an empty list
$logs = emptyList();

// When there are no results, the callback is not executed
$logs->maybe(function(Klist $items) {
    echo "This doesn't get echoed";
});

Real-World Example: Checking conditions with all and any

$orders = listOf(100, 250, 90, 300);

$allAbove50 = $orders->all(fn($amount) => $amount > 50); // true
$anyAbove500 = $orders->any(fn($amount) => $amount > 500); // false

if ($orders->any(fn($o) => $o > 100)) {
    echo "User gets free shipping and insurance!";
}

Comparison to native PHP:

// Traditional PHP
array_filter(array_map(fn($x) => $x * 2, [1, 2, 3, 4]), fn($x) => $x > 5);

// With Axpecto
listOf(1, 2, 3, 4)
    ->map(fn($x) => $x * 2)
    ->filter(fn($x) => $x > 5);

🧠 Dependency Injection

Axpecto's DI container autowires your services, resolves dependencies via type hints, and supports injection via #[Inject].

$container = new Container();

$app = $container->get(MyApplication::class);

You can also register services manually:

$container->bind(CacheInterface::class, MyCache::class);
$container->addClassInstance(Logger::class, new CustomLogger());
$container->addValue('api_key', 'abcdef123');

Constructor-Based Injection (Preferred)

The most common way to inject dependencies in Axpecto is through the constructor. The container resolves all parameters by type and automatically wires them:

class ReportGenerator {
    public function __construct(
        private LoggerInterface $logger,
        private ReportRepository $repository
    ) {}

    public function generate() {
        $this->logger->info("Generated: " . count($this->repository->getAll()) . " reports");
    }
}

$reporter = $container->get(ReportGenerator::class);

// Generate reports
$reporter->generate();

Property Injection (when constructor-based injection is not ideal)

$container->addValue('site_name', 'MyApp');
$container->bind(MailerInterface::class, SMTPMailer::class);

class WelcomeMailer {
    #[Inject] private string $site_name;
    #[Inject] private MailerInterface $mailer;

    public function send($to) {
        $this->mailer->send($to, "Welcome to {$this->site_name}!");
    }
}

Example: Reusing and re-binding implementations

$container->bind(LoggerInterface::class, FileLogger::class);

// Replace with a mock during testing
$container->addClassInstance(LoggerInterface::class, new MockLogger());

📍 Aspect-Oriented Programming

You can define annotations that intercept method calls, allowing you to:

• Apply caching, logging, or validation logic.
• Modify arguments or results.
• Inject cross-cutting behavior without polluting your core logic.

#[HtmlOutput(
  path: 'template.php',
  styles: ['main.css'],
  script_data_provider: fn($result) => ['data' => $result],
)]
public function renderDashboard() {
    return [ 'user' => 'Jane' ];
}

The method execution is intercepted by HtmlOutputHandler, which transforms the output into a templated HTML page.

---

🏗️ Build-Time Annotations (Dynamic Class Generation)

Declare abstract classes with metadata that Axpecto will build into concrete implementations:

#[Repository(entityClass: Customer::class)]
abstract class CustomerRepository {
    public abstract function findByIdGreaterThanAndEmailOrEmailIsNull($id, $email);
}

Axpecto parses this and auto-generates logic to resolve database access without manual boilerplate.

🧪 Example Build Annotation: #[Service]

#[Service]
abstract class ReportService {
    public abstract function generate();
}

class ServiceBuildHandler implements BuildHandler {
    public function intercept(Annotation $annotation, BuildContext $context): void {
        if (! $annotation instanceof Service || $annotation->getAnnotatedMethod() !== null) return;

        foreach ($context->getAbstractMethods() as $method) {
            $context->addMethod(
                $method->getName(),
                "public function {$method->getName()}()",
                "// Auto-generated service method implementation"
            );
        }
    }
}

---

⚡ Method Execution Interception

Intercept method calls to apply logic dynamically.

Example: #[Cacheable]

#[Cacheable(ttl: 60)]
public function getLatestPosts() {
    return $this->query->fetch();
}

class CacheableHandler implements MethodExecutionHandler {
    public function intercept(MethodExecutionContext $ctx): mixed {
        $key = md5($ctx->className . $ctx->methodName . serialize($ctx->arguments));
        $cache = new SimpleCache();

        if ($cache->has($key)) {
            return $cache->get($key);
        }

        $result = $ctx->proceed();
        $cache->set($key, $result, $ctx->getAnnotation()->ttl);

        return $result;
    }
}

Example: #[Logged]

#[Logged]
public function processOrder($orderId) {
    // Core logic here
}

class LoggedHandler implements MethodExecutionHandler {
    public function intercept(MethodExecutionContext $ctx): mixed {
        error_log("Entering {$ctx->className}::{$ctx->methodName}");
        $result = $ctx->proceed();
        error_log("Exiting {$ctx->className}::{$ctx->methodName}");
        return $result;
    }
}

🗃️ Using #[Repository] in Axpecto

⚠️ The repository feature is under construction and could change.

The #[Repository] annotation in Axpecto allows you to define data access logic declaratively by marking an interface or abstract class as a repository. When the container encounters this class, Axpecto will build the implementation automatically, parsing method names and generating queries based on conventions and entity metadata.

🔍 What #[Repository] Does

When you annotate a class with #[Repository], Axpecto:

1. Reads the entityClass that this repository manages.
2. Parses abstract method names to extract conditions (e.g., findByIdAndEmailIsNotNull).
3. Generates runtime code that:
   • Builds a Criteria object.
   • Maps entity properties to database fields.
   • Calls the appropriate persistence logic.
4. Injects dependencies like the entity mapper and persistence strategy.

This behavior is defined by the RepositoryBuildHandler, which is automatically injected and associated with the annotation. This defines a CustomerRepository where the methods will be built automatically. When you call:

---

✅ Basic Example

#[Repository(entityClass: Customer::class)]
abstract class CustomerRepository {
    public abstract function findByEmail(string $email);
    public abstract function findByUsernameOrEmail(string $username, string $email);
}
// This defines a CustomerRepository where the methods will be built automatically. When you call:
$repo = $container->get(CustomerRepository::class);
$customer = $repo->findByEmail('[email protected]');

Axpecto builds the logic to create a Criteria, apply the field conditions, and use the underlying storage to fetch and map the entity.

🧠 Behind the Scenes

The handler responsible is RepositoryBuildHandler, which:

• Uses ReflectionUtils to inspect the entity and repository class.
• Parses method names using RepositoryMethodNameParser.
• Resolves annotations like #[Entity], #[Mapping], #[Id], etc.
• Maps method parameters to conditions.
• Outputs real executable code injected at runtime via the BuildContext.

// Example generated logic for a method like:
public abstract function findByIdGreaterThanAndEmailOrEmailIsNull($id, $email);

// ...will result in a criteria similar to:
$criteria->addCondition('id', $id, Operator::GREATER_THAN);
$criteria->addCondition('email', $email, Operator::EQUALS, LogicOperator::OR);
$criteria->addCondition('email', null, Operator::IS_NULL, LogicOperator::OR);

💡 Entity Example

#[Entity(storage: MysqlPersistenceStrategy::class, table: 'customer')]
class Customer {
    public function __construct(
        #[Id(autoIncrement: true)]
        public ?int $id,
        #[UniqueNotNull]
        public string $username,
        #[UniqueNotNull]
        public string $email,
        #[Column(isNullable: true)]
        public string $password,
        #[Timestamp]
        public DateTime $createdAt,
        #[Timestamp(onUpdate: Column::CURRENT_TIMESTAMP)]
        public DateTime $updatedAt,
        #[UniqueNotNull]
        public string $displayName,
    ) {}
}

🧪 Tips and Best Practices

• ✅ Use clear, expressive method names — they’re parsed to build conditions.
• ✅ Combine with #[Column] annotations on entities to customize DB fields.
• ⚠️ Avoid overly complex method names with too many logical branches.
• ✅ Great for CRUD interfaces, admin panels, or quick scaffolding.

🛠 Advanced Ideas

You can extend this concept with:

• #[Entity(storage: MyCustomStrategy::class)] for custom persistence backends.
• Auto-generated GraphQL endpoints based on repository methods.
• Caching, logging, or access control annotations layered on top of repositories.

🔗 Architecture & Philosophy

Axpecto is a meta-framework. It's:

• Annotation-first: Behavior is declarative, composable, and introspectable.
• AI-extendable: Built to be easily parsed, modified, and extended by AI.
• Framework-agnostic: Use in Laravel, Symfony, WordPress, or your own stack.
• Composable: Swap DI, AOP, or collections independently.
