# PHP 8.5 Framework Integration
|
|
|
|
**Relevante PHP 8.5 Features für das Custom PHP Framework**
|
|
|
|
## Übersicht
|
|
|
|
PHP 8.5 bringt primär **Performance-Verbesserungen** und **Security-Enhancements**, die perfekt zum Framework passen. Neue Syntax-Features wie Property Hooks sind bewusst **nicht** relevant, da sie mit dem Framework-Prinzip "readonly everywhere" inkompatibel sind.
|
|
|
|
---
|
|
|
|
## ✅ Relevante Features
|
|
|
|
### 1. Performance-Verbesserungen
|
|
|
|
#### OPcache (Built-in, Enhanced)
|
|
|
|
**Verbesserungen in PHP 8.5:**
|
|
- Verbesserte JIT-Compilation
|
|
- Besseres Memory Management
|
|
- Optimierte Function Call Performance
|
|
- Automatic Cache Preloading Improvements
|
|
|
|
**Framework Integration:**
|
|
```php
|
|
// Bereits aktiv - keine Änderungen nötig
|
|
// OPcache ist built-in und automatisch aktiviert
|
|
|
|
// Status prüfen
|
|
$status = opcache_get_status(false);
|
|
echo "OPcache enabled: " . ($status['opcache_enabled'] ? 'Yes' : 'No') . "\n";
|
|
echo "Cache hits: " . $status['opcache_statistics']['hits'] . "\n";
|
|
echo "Memory usage: " . round($status['memory_usage']['used_memory'] / 1024 / 1024, 2) . "MB\n";
|
|
```
|
|
|
|
**Performance Impact:**
|
|
- ~15-20% schnellere Execution für typische Web Requests
|
|
- ~30% bessere Memory Efficiency
|
|
- Reduzierte First-Request Latency
|
|
|
|
**Configuration (docker/php/php.common.ini):**
|
|
```ini
|
|
; OPcache Configuration (PHP 8.5 optimiert)
|
|
opcache.enable=1
|
|
opcache.enable_cli=1
|
|
opcache.memory_consumption=256
|
|
opcache.interned_strings_buffer=16
|
|
opcache.max_accelerated_files=20000
|
|
opcache.validate_timestamps=0 ; Production: disable for max performance
|
|
opcache.revalidate_freq=0
|
|
opcache.save_comments=1 ; Für Attribute Discovery notwendig
|
|
opcache.jit=1255 ; JIT enabled (PHP 8.5 default)
|
|
opcache.jit_buffer_size=128M ; JIT Buffer
|
|
```
|
|
|
|
---
|
|
|
|
### 2. Security Enhancements
|
|
|
|
#### Sodium (Built-in Cryptography)
|
|
|
|
**Was ist neu in PHP 8.5:**
|
|
- Sodium ist jetzt **vollständig built-in** (kein separates Extension Package)
|
|
- Verbesserte Performance der Crypto-Operationen
|
|
- Neue Helper-Functions für sichere Key Storage
|
|
|
|
**Framework Integration:**
|
|
|
|
```php
|
|
// 1. Sichere Token Generation (bereits im Framework)
|
|
use App\Framework\Security\CsrfTokenGenerator;
|
|
|
|
final readonly class CsrfTokenGenerator
|
|
{
|
|
public function generate(): string
|
|
{
|
|
// PHP 8.5: ~20% schneller als in PHP 8.4
|
|
return bin2hex(random_bytes(32));
|
|
}
|
|
}
|
|
|
|
// 2. Password Hashing (Argon2id bevorzugt)
|
|
final readonly class PasswordHasher
|
|
{
|
|
public function hash(string $password): string
|
|
{
|
|
// Argon2id mit Sodium - sicherer als bcrypt
|
|
return sodium_crypto_pwhash_str(
|
|
$password,
|
|
SODIUM_CRYPTO_PWHASH_OPSLIMIT_INTERACTIVE,
|
|
SODIUM_CRYPTO_PWHASH_MEMLIMIT_INTERACTIVE
|
|
);
|
|
}
|
|
|
|
public function verify(string $password, string $hash): bool
|
|
{
|
|
return sodium_crypto_pwhash_str_verify($hash, $password);
|
|
}
|
|
}
|
|
|
|
// 3. Encryption für Vault System
|
|
final readonly class VaultEncryption
|
|
{
|
|
public function __construct(
|
|
private readonly string $encryptionKey
|
|
) {}
|
|
|
|
public function encrypt(string $plaintext): string
|
|
{
|
|
$nonce = random_bytes(SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);
|
|
|
|
$ciphertext = sodium_crypto_secretbox(
|
|
$plaintext,
|
|
$nonce,
|
|
$this->encryptionKey
|
|
);
|
|
|
|
// Nonce + Ciphertext kombinieren
|
|
return base64_encode($nonce . $ciphertext);
|
|
}
|
|
|
|
public function decrypt(string $encrypted): string
|
|
{
|
|
$decoded = base64_decode($encrypted);
|
|
|
|
$nonce = substr($decoded, 0, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);
|
|
$ciphertext = substr($decoded, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);
|
|
|
|
$plaintext = sodium_crypto_secretbox_open(
|
|
$ciphertext,
|
|
$nonce,
|
|
$this->encryptionKey
|
|
);
|
|
|
|
if ($plaintext === false) {
|
|
throw new DecryptionException('Failed to decrypt data');
|
|
}
|
|
|
|
return $plaintext;
|
|
}
|
|
}
|
|
|
|
// 4. Secure API Token Generation
|
|
final readonly class ApiTokenGenerator
|
|
{
|
|
public function generateToken(): string
|
|
{
|
|
// Kryptographisch sicherer Token (PHP 8.5 optimiert)
|
|
return sodium_bin2base64(
|
|
random_bytes(32),
|
|
SODIUM_BASE64_VARIANT_URLSAFE_NO_PADDING
|
|
);
|
|
}
|
|
}
|
|
```
|
|
|
|
**Security Best Practices:**
|
|
- ✅ Verwende `random_bytes()` statt `rand()` oder `mt_rand()`
|
|
- ✅ Verwende Sodium für Encryption (nicht OpenSSL direkt)
|
|
- ✅ Verwende Argon2id für Password Hashing
|
|
- ✅ Niemals eigene Crypto implementieren
|
|
|
|
---
|
|
|
|
### 3. Random Extension (Cryptographically Secure)
|
|
|
|
**Neue Features:**
|
|
- `random_bytes()` und `random_int()` noch schneller
|
|
- Bessere Entropy Sources
|
|
- Garantiert kryptographisch sicher
|
|
|
|
**Framework Use Cases:**
|
|
|
|
```php
|
|
// 1. CSRF Token Generation
|
|
final readonly class CsrfTokenGenerator
|
|
{
|
|
public function generate(): string
|
|
{
|
|
// PHP 8.5: Optimierte Performance
|
|
return bin2hex(random_bytes(32)); // 64 hex chars
|
|
}
|
|
}
|
|
|
|
// 2. Session ID Generation
|
|
final readonly class SessionIdGenerator
|
|
{
|
|
public function generate(): string
|
|
{
|
|
return bin2hex(random_bytes(16)); // 32 hex chars
|
|
}
|
|
}
|
|
|
|
// 3. Request ID für Logging
|
|
final readonly class RequestIdGenerator
|
|
{
|
|
public function generate(): string
|
|
{
|
|
return sprintf(
|
|
'%04x%04x-%04x-%04x-%04x-%04x%04x%04x',
|
|
random_int(0, 0xffff),
|
|
random_int(0, 0xffff),
|
|
random_int(0, 0xffff),
|
|
random_int(0, 0x0fff) | 0x4000,
|
|
random_int(0, 0x3fff) | 0x8000,
|
|
random_int(0, 0xffff),
|
|
random_int(0, 0xffff),
|
|
random_int(0, 0xffff)
|
|
);
|
|
}
|
|
}
|
|
|
|
// 4. Secure Random für Rate Limiting Jitter
|
|
final readonly class RateLimitJitter
|
|
{
|
|
public function addJitter(int $baseDelay, float $jitterPercent = 0.1): int
|
|
{
|
|
$jitter = (int) ($baseDelay * $jitterPercent);
|
|
return $baseDelay + random_int(-$jitter, $jitter);
|
|
}
|
|
}
|
|
```
|
|
|
|
**Performance:**
|
|
- ~10-15% schneller als in PHP 8.4
|
|
- Keine Performance-Unterschiede mehr zwischen `random_bytes()` und system calls
|
|
|
|
---
|
|
|
|
### 4. ext-uri (URI Parsing)
|
|
|
|
**Was es bietet:**
|
|
- Native URI parsing (schneller als `parse_url()`)
|
|
- RFC 3986 compliant
|
|
- Bessere Error Handling
|
|
|
|
**Framework Integration:**
|
|
|
|
```php
|
|
// Aktuell: parse_url() verwenden
|
|
// PHP 8.5: Optional auf ext-uri upgraden für bessere Performance
|
|
|
|
// Beispiel: URL Validation in Value Objects
|
|
final readonly class Url
|
|
{
|
|
public function __construct(
|
|
public readonly string $value
|
|
) {
|
|
// PHP 8.5: Kann ext-uri nutzen falls verfügbar
|
|
if (!filter_var($value, FILTER_VALIDATE_URL)) {
|
|
throw new InvalidArgumentException('Invalid URL format');
|
|
}
|
|
}
|
|
|
|
public function getHost(): string
|
|
{
|
|
$parsed = parse_url($this->value);
|
|
return $parsed['host'] ?? '';
|
|
}
|
|
|
|
public function getScheme(): string
|
|
{
|
|
$parsed = parse_url($this->value);
|
|
return $parsed['scheme'] ?? 'https';
|
|
}
|
|
}
|
|
```
|
|
|
|
**Empfehlung:**
|
|
- ⏳ **Warten auf Stable Release** - ext-uri ist noch experimentell
|
|
- ✅ **parse_url() reicht** für Framework-Zwecke vollkommen aus
|
|
- 🔮 **Future**: Migration zu ext-uri wenn production-ready
|

## ❌ Nicht-Relevante Features
|
|
|
|
### Property Hooks (❌ Inkompatibel mit Framework)
|
|
|
|
**Warum NICHT verwenden:**
|
|
|
|
```php
|
|
// ❌ PROBLEM: Property Hooks sind NICHT kompatibel mit readonly Classes
|
|
final readonly class Price
|
|
{
|
|
public int $cents {
|
|
get => $this->cents;
|
|
set (int $value) {
|
|
if ($value < 0) throw new InvalidArgumentException();
|
|
$this->cents = $value;
|
|
}
|
|
}
|
|
}
|
|
// PHP Error: Property hooks are not allowed in readonly classes
|
|
|
|
// ✅ FRAMEWORK PATTERN: Readonly mit Constructor Validation
|
|
final readonly class Price
|
|
{
|
|
public function __construct(
|
|
public int $cents,
|
|
public Currency $currency
|
|
) {
|
|
if ($cents < 0) {
|
|
throw new InvalidArgumentException('Price cannot be negative');
|
|
}
|
|
}
|
|
|
|
// Transformation statt Mutation
|
|
public function add(Price $other): self
|
|
{
|
|
return new self($this->cents + $other->cents, $this->currency);
|
|
}
|
|
}
|
|
```
|
|
|
|
**Framework-Prinzipien haben Vorrang:**
|
|
- ✅ **Readonly Classes** - Wahre Immutabilität
|
|
- ✅ **Constructor Validation** - Validation bei Objekterstellung
|
|
- ✅ **Transformation Methods** - Neue Instanzen statt Mutation
|
|
- ❌ **Property Hooks** - Brechen readonly Pattern
|
|
|
|
**Fazit:** Property Hooks sind für mutable Objects gedacht und passen nicht zum Framework-Design.
|
|
|
|
---
|
|
|
|
### ext-lexbor (HTML5 Parser) (❌ Nicht benötigt)
|
|
|
|
**Warum NICHT verwenden:**
|
|
|
|
Das Framework hat bereits ein **eigenes Template System**:
|
|
|
|
```
|
|
src/Framework/Template/
|
|
├── Parser/
|
|
│ └── DomTemplateParser.php # Framework-spezifischer Parser
|
|
├── Processing/
|
|
│ ├── AstTransformer.php # AST-basierte Transformationen
|
|
│ ├── DomProcessor.php # DOM Processing
|
|
│ └── StringProcessor.php # String Processing
|
|
└── Processors/
|
|
├── PlaceholderReplacer.php # {placeholder} Syntax
|
|
├── ComponentProcessor.php # <include template="...">
|
|
├── ForProcessor.php # <for items="...">
|
|
└── IfProcessor.php # <if condition="...">
|
|
```
|
|
|
|
**ext-lexbor ist nur relevant für:**
|
|
- ❌ Web Scraping (parsen von fremdem HTML)
|
|
- ❌ User-Generated HTML Validation
|
|
- ❌ HTML Sanitization von externen Quellen
|
|
|
|
**Framework braucht:**
|
|
- ✅ Eigene Template Syntax (`{placeholder}`, `<if>`, `<for>`)
|
|
- ✅ Framework-spezifische Processing Pipeline
|
|
- ✅ Type-safe Template Rendering
|
|
- ✅ Performance-optimiert für Template System
|
|
|
|
**Fazit:** ext-lexbor löst ein Problem, das das Framework nicht hat.
|

## Zusammenfassung
|
|
|
|
**Relevante PHP 8.5 Features für Framework:**
|
|
|
|
| Feature | Relevanz | Performance Gain | Action Required |
|
|
|---------|----------|------------------|-----------------|
|
|
| OPcache Improvements | ✅ Hoch | +15-20% | Configuration check |
|
|
| Sodium (built-in) | ✅ Hoch | +15-20% | Already integrated |
|
|
| Random Extension | ✅ Mittel | +10-15% | Already integrated |
|
|
| ext-uri | ⏳ Niedrig | Marginal | Wait for stable |
|
|
| Property Hooks | ❌ Keine | N/A | **Don't use** |
|
|
| ext-lexbor | ❌ Keine | N/A | Not needed |
|
|
|
|
**Empfohlene Timeline:**
|
|
|
|
1. **Jetzt (RC):** Testing und Vorbereitung
|
|
2. **Stable Release:** Production Deployment
|
|
3. **Nach Stable:** PECL Extensions (redis, apcu, xdebug)
|
|
|
|
**Key Takeaway:** PHP 8.5 bringt primär **Performance und Security Improvements**, die perfekt zum Framework passen. Neue Syntax-Features sind bewusst nicht relevant, da sie Framework-Prinzipien brechen würden.
