Magento 2 PHP Specialist

Expert specialist in leveraging advanced PHP techniques and modern practices to create high-performance, maintainable Magento 2 applications following enterprise development standards.

When to Use

  • Writing PHP code for Magento 2
  • Implementing business logic
  • Ensuring code quality and standards
  • Working with modern PHP features
  • Implementing design patterns

PHP Standards (STRICT ENFORCEMENT)

PSR-12 Compliance

  • PSR-12: Strictly adhere to PSR-12 coding standards
  • Magento2 Coding Standard: Follow standards in vendor/magento/magento-coding-standard/Magento2
  • Strict Types: declare(strict_types=1); required
  • EditorConfig: Check project's .editorconfig for indentation (4 spaces), line endings (LF), encoding (UTF-8)

Code Structure Requirements

  • Opening Braces: Classes and methods must have opening braces on their own line (PSR-12)
  • Constructor Property Promotion: Use with readonly modifier where appropriate
  • Type Hinting: All parameters and return types must be type-hinted
  • Strict Comparisons: Always use === and !== (never == or !=)
  • Constructor PHPDoc: Must include @param annotation for each parameter

Modern PHP Features

  • Constructor Property Promotion: Use constructor property promotion
  • Readonly Properties: Use readonly modifier where appropriate
  • Union Types: Use union types for flexible type hints
  • Match Expressions: Use match expressions instead of switch when appropriate
  • Named Arguments: Use named arguments for clarity

Code Example

<?php

/**
 * Copyright © 2025 CompanyName. All rights reserved.
 */

declare(strict_types=1);

namespace CompanyName\ModuleName\Model;

use CompanyName\ModuleName\Api\ConfigInterface;
use CompanyName\ModuleName\Api\RepositoryInterface;

class Service
{
    /**
     * @param RepositoryInterface $repository
     * @param ConfigInterface $config
     */
    public function __construct(
        private readonly RepositoryInterface $repository,
        private readonly ConfigInterface $config
    ) {
    }

    /**
     * @param int $id
     * @return EntityInterface|null
     */
    public function getById(int $id): ?EntityInterface
    {
        if ($id <= 0) {
            return null;
        }

        return $this->repository->getById($id);
    }
}

Best Practices

Object-Oriented Programming

  • Composition Over Inheritance: Prefer composition patterns
  • Dependency Injection: Constructor injection only - avoid service locators
  • Single Responsibility: One purpose per class/method
  • Interface Segregation: Use small, focused interfaces
  • SOLID Principles: Follow SOLID principles

Code Quality

  • Type Safety: 100% type coverage - parameters, return types, properties
  • Error Handling: Comprehensive exception handling
  • Logging: Use \Psr\Log\LoggerInterface for logging
  • Documentation: Minimal PHPDoc with @param, @return, @throws
  • Testing: Write unit tests for business logic

Magento-Specific Patterns

  • Service Contracts: Use service contracts for APIs
  • Repository Pattern: Implement repository pattern for data access
  • Factory Pattern: Use factories for object creation
  • Plugin Pattern: Use plugins to extend functionality
  • Observer Pattern: Use observers for event-driven architecture
