Modern PHP Syntax - Code Examples & Professional Implementation

Object-Oriented Programming - Expert Analysis & Best Practices

// Modern PHP 8.3 Class Definition with Attributes <?php declare(strict_types=1); namespace WebKodlama\Core; use WebKodlama\Interfaces\DatabaseInterface; use WebKodlama\Traits\LoggerTrait; #[ApiResource] #[Table(name: 'users')] class User implements DatabaseInterface { use LoggerTrait; public function __construct( private readonly int $id, private string $name, private string $email, private ?DateTime $createdAt = null ) { $this->createdAt ??= new DateTime(); $this->logActivity('User created'); } // Type-safe getter methods public function getId(): int { return $this->id; } public function getName(): string { return $this->name; } // Email validation with modern PHP features public function setEmail(string $email): void { if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { throw new InvalidArgumentException('Invalid email format'); } $this->email = $email; $this->logActivity('Email updated'); } // Database operations with error handling public function save(): bool { try { $query = "INSERT INTO users (name, email, created_at) VALUES (?, ?, ?)"; $result = $this->executeQuery($query, [ $this->name, $this->email, $this->createdAt->format('Y-m-d H:i:s') ]); return $result !== false; } catch (Exception $e) { $this->logError('User save failed: ' . $e->getMessage()); return false; } } }

Modern PHP development'ta constructor property promotion, readonly properties ve strict typing kullanarak code quality'yi artırın. Type declarations hem IDE support'unu geliştirir hem de runtime errors'ı azaltır.

Asynchronous Programming - Modern PHP Concurrency & Performance

// ReactPHP ile Asynchronous Operations <?php require_once 'vendor/autoload.php'; use React\EventLoop\Factory; use React\Http\Browser; use React\Promise\Promise; class AsyncApiClient { private $loop; private $browser; public function __construct() { $this->loop = Factory::create(); $this->browser = new Browser($this->loop); } // Parallel API requests - Performance optimized public function fetchMultipleEndpoints(array $urls): Promise { $promises = []; foreach ($urls as $key => $url) { $promises[$key] = $this->browser ->get($url) ->then(function ($response) { return json_decode($response->getBody(), true); }) ->otherwise(function ($error) { error_log('API Request failed: ' . $error->getMessage()); return null; }); } return React\Promise\all($promises); } public function run(): void { $this->loop->run(); } } // Usage Example $client = new AsyncApiClient(); $urls = [ 'weather' => 'https://api.weather.com/current', 'news' => 'https://api.news.com/headlines', 'stock' => 'https://api.stock.com/prices' ]; $client->fetchMultipleEndpoints($urls) ->then(function ($results) { foreach ($results as $key => $data) { echo "$key: " . json_encode($data) . "\n"; } }); $client->run();

Async programming ile multiple API calls'ı paralel olarak execute ederek application performance'ını dramatically improve edebilirsiniz. ReactPHP ecosystem'i modern PHP'de concurrency için industry standard'dır.

PHP Troubleshooting Guide - Error Analysis & Professional Solutions

Common PHP Errors - Expert Analysis & Implementation Solutions

Fatal Error

Memory Limit Exceeded

Error: "Fatal error: Allowed memory size exhausted"

Çözüm: Memory usage optimization, ini_set('memory_limit', '256M'), efficient data structures kullanın.

// Memory efficient processing foreach ($largeArray as $item) { unset($item); // Memory cleanup }

Parse Error

Syntax Error

Error: "Parse error: syntax error, unexpected..."

Çözüm: IDE syntax highlighting, PHP linting tools ve proper debugging workflow implement edin.

Database Error

Connection Failed

Error: "SQLSTATE[HY000] [2002] Connection refused"

Çözüm: Connection pooling, retry mechanisms ve proper error handling uygulayın.

try { $pdo = new PDO($dsn, $user, $pass); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { error_log($e->getMessage()); }

Security Issue

SQL Injection Risk

Problem: User input directly concatenated in queries

Çözüm: Prepared statements, input validation ve parameterized queries kullanın.

SQL injection attacks'ları önlemek için asla user input'u directly SQL queries'e concatenate etmeyin. Prepared statements ve input sanitization critical security practices'dır.

PHP Performance Optimization - Adım Adım Rehber

Professional Performance Tuning

OPcache Configuration
Bytecode caching ile dramatic performance improvements. Production environment'larda OPcache enable etmek %30-50 performance boost sağlar.
; php.ini configuration opcache.enable=1 opcache.memory_consumption=256 opcache.max_accelerated_files=20000 opcache.revalidate_freq=0
Database Query Optimization
N+1 query problems'ı eliminate edin, proper indexing implement edin ve connection pooling kullanın. Query caching mechanisms active hale getirin.
Memory Management
Large datasets için generators kullanın, unnecessary variable references'ları unset edin ve memory profiling tools ile bottlenecks identify edin.
function processLargeDataset(): Generator { for ($i = 0; $i < 1000000; $i++) { yield expensiveCalculation($i); } }
Caching Strategies
Redis/Memcached implement edin, HTTP caching headers optimize edin ve static content için CDN integration yapın.

Performance optimization'da systematic approach benimseyin: Profiling → Bottleneck identification → Targeted optimization → Measurement → Iteration cycle'ı follow edin.
