PHP Hosting

🎯 Key Points

• ✓Shared hosting - Billigst, fint til små sites og WordPress
• ✓VPS hosting - Bedre performance med dedikerede ressourcer
• ✓Cloud hosting - Skalerbar infrastruktur fra AWS, DigitalOcean
• ✓PHP versioner - Mulighed for at skifte mellem PHP 7.4, 8.0, 8.1, 8.2
• ✓Extensions - Support for nødvendige PHP extensions
• ✓Database - MySQL eller PostgreSQL support
• ✓SSL certifikater - Gratis Let's Encrypt integration
• ✓Deployment - Git, FTP, eller SSH adgang
• ✓Performance - PHP-FPM, OPcache, memory limits
• ✓Cron jobs - Scheduled tasks til maintenance

💻 Kode Eksempel

<?php

// .htaccess for clean URLs på shared hosting
// RewriteEngine On
// RewriteCond %{REQUEST_FILENAME} !-f
// RewriteCond %{REQUEST_FILENAME} !-d
// RewriteRule ^(.*)$ index.php/$1 [L]

// Environment detection
if (getenv('APP_ENV') === 'production') {
    error_reporting(0);
    ini_set('display_errors', '0');
} else {
    error_reporting(E_ALL);
    ini_set('display_errors', '1');
}

// Database connection med environment variables
$config = [
    'host' => getenv('DB_HOST') ?: 'localhost',
    'database' => getenv('DB_NAME'),
    'username' => getenv('DB_USER'),
    'password' => getenv('DB_PASS')
];

try {
    $dsn = "mysql:host={$config['host']};dbname={$config['database']}";
    $pdo = new PDO($dsn, $config['username'], $config['password']);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully";
} catch (PDOException $e) {
    error_log($e->getMessage());
    echo "Connection failed. Check logs.";
}

⭐ Best Practices

• ✓Vælg hosting med opdateret PHP version (minimum 8.0)
• ✓Brug environment variables til følsomme data
• ✓Aktiver OPcache for bedre performance
• ✓Sæt passende memory_limit og max_execution_time
• ✓Brug SSL certifikater (Let's Encrypt)
• ✓Hold PHP og dependencies opdateret
• ✓Brug Composer til dependency management
• ✓Implementer proper error logging
