HasToArray

Reflection-based toArray() trait for DTOs implementing Arrayable.

Signature

php

<?php

namespace Studiometa\Foehn\Concerns;

trait HasToArray
{
    public function toArray(): array;
    protected function propertyToKey(string $name): string;
}

Behavior

Reads all public instance properties via reflection
Converts camelCase names to snake_case keys (e.g., backgroundImage → background_image)
Recursively flattens nested Arrayable objects
Recursively flattens Arrayable items in arrays
Skips uninitialized and static properties

Customization

Override propertyToKey() to change the key mapping:

php

final readonly class MyContext implements Arrayable
{
    use HasToArray;

    public function __construct(
        public string $firstName,
    ) {}

    // Keep camelCase keys
    protected function propertyToKey(string $name): string
    {
        return $name;
    }
}

(new MyContext('John'))->toArray();
// ['firstName' => 'John'] instead of ['first_name' => 'John']
