Utility trait and helpers for PHP 8.1+ native enums.

Requirements
------------

[](#requirements)

- PHP 8.2+

Installation
------------

[](#installation)

```
composer require philiprehberger/php-enum-utils
```

Usage
-----

[](#usage)

### Adding the trait to your enum

[](#adding-the-trait-to-your-enum)

```
use PhilipRehberger\EnumUtils\EnumUtils;
use PhilipRehberger\EnumUtils\Attributes\Label;
use PhilipRehberger\EnumUtils\Attributes\Description;

enum Status: string
{
    use EnumUtils;

    #[Label('Pending Review')]
    #[Description('The item is waiting for review')]
    case Pending = 'pending';

    #[Label('In Progress')]
    case InProgress = 'in_progress';

    case Completed = 'completed';
}
```

### Lookup by name

[](#lookup-by-name)

```
$case = Status::fromName('pending');      // Status::Pending (case-insensitive)
$case = Status::tryFromName('unknown');   // null
```

### Listing cases

[](#listing-cases)

```
Status::names();   // ['Pending', 'InProgress', 'Completed']
Status::values();  // ['pending', 'in_progress', 'completed']
Status::count();   // 3
```

### Arrays for forms and selects

[](#arrays-for-forms-and-selects)

```
Status::toSelectArray();
// ['pending' => 'Pending Review', 'in_progress' => 'In Progress', 'completed' => 'Completed']

Status::toArray();
// ['Pending' => 'pending', 'InProgress' => 'in_progress', 'Completed' => 'completed']
```

### Filtering cases

[](#filtering-cases)

```
// Filter by a custom predicate
$active = Status::casesWhere(fn (Status $s) => $s !== Status::Completed);
// [Status::Pending, Status::InProgress]

// Check if a case is among a given set
Status::Pending->in(Status::Pending, Status::InProgress);   // true
Status::Completed->in(Status::Pending, Status::InProgress); // false
```

### Random case and comparison

[](#random-case-and-comparison)

```
$case = Status::random();                        // A random Status case
Status::Pending->equals(Status::Pending);        // true
Status::Pending->equals(Status::Completed);      // false
```

### Collections

[](#collections)

```
use PhilipRehberger\EnumUtils\EnumCollection;

// Wrap all cases in a fluent collection
$active = Status::collect()
    ->filter(fn (Status $s) => $s !== Status::Completed)
    ->sortBy(fn (Status $s) => $s->value)
    ->toArray();

// Get the first matching case
$first = Status::collect()->first(fn (Status $s) => str_starts_with($s->value, 'p'));

// Group cases
$grouped = Status::collect()->groupBy(fn (Status $s) => $s === Status::Completed ? 'done' : 'active');

// Partition into two arrays: [matching, non-matching]
[$pending, $rest] = Status::collect()->partition(fn (Status $s) => $s === Status::Pending);
```

### Serialization

[](#serialization)

```
// Serialize all cases to JSON
$json = Status::toJson();
// [{"name":"Pending","value":"pending","label":"Pending Review","description":"..."},...]

// Deserialize back to enum cases
$cases = Status::fromJson($json);  // [Status::Pending, Status::InProgress, ...]

// Get value => label map
$map = Status::toMap();
// ['pending' => 'Pending Review', 'in_progress' => 'In Progress', 'completed' => 'Completed']
```

### State Transitions

[](#state-transitions)

```
use PhilipRehberger\EnumUtils\Attributes\AllowedTransitions;

enum OrderStatus: string
{
    use EnumUtils;

    #[AllowedTransitions(self::Processing, self::Cancelled)]
    case Pending = 'pending';

    #[AllowedTransitions(self::Shipped, self::Cancelled)]
    case Processing = 'processing';

    #[AllowedTransitions(self::Delivered)]
    case Shipped = 'shipped';

    case Delivered = 'delivered';
    case Cancelled = 'cancelled';
}

OrderStatus::Pending->canTransitionTo(OrderStatus::Processing);  // true
OrderStatus::Pending->canTransitionTo(OrderStatus::Shipped);     // false
OrderStatus::Pending->allowedTransitions();  // [OrderStatus::Processing, OrderStatus::Cancelled]
OrderStatus::Delivered->allowedTransitions(); // [] (no transitions defined)
```

### Reading attributes with EnumMeta

[](#reading-attributes-with-enummeta)

```
use PhilipRehberger\EnumUtils\EnumMeta;

EnumMeta::label(Status::Pending);         // 'Pending Review'
EnumMeta::label(Status::Completed);       // 'Completed' (fallback: humanized name)
EnumMeta::description(Status::Pending);   // 'The item is waiting for review'
EnumMeta::description(Status::Completed); // null
EnumMeta::labels(Status::class);          // ['pending' => 'Pending Review', ...]
```
