How does PHP 8 Enum Casting work on Eloquent Model attributes?
❓ Interview Prompt: Explain PHP 8 Backed Enums, casting Eloquent attributes to Enums ($casts = ['status' => PostStatus::class]), and type safety.
Laravel allows casting Eloquent model attributes directly to PHP 8 Backed Enums:
Benefits:
•
Type Safety: Guarantees that attribute values match defined Enum cases.
•
Domain Logic: Enums can contain helper methods ('$post->status->label()').
•
Automatic Serialization: Converts Backed Enum scalar values to database strings automatically.
Code Implementation Example
php
<?php
namespace AppEnums;
enum OrderStatus: string {
case Pending = 'pending';
case Processing = 'processing';
case Completed = 'completed';
}
// In Model:
protected $casts = [
'status' => OrderStatus::class,
];💡Casting Eloquent model attribute to PHP 8 Backed Enum.
🎯 Interview Key Takeaway
Cast Eloquent attributes to PHP 8 Backed Enums for strict type safety and clean domain status management.
