Source: https://github.com/tourze/enum-extra/blob/master/README.md

Installs the tourze/enum-extra package using Composer. This command is essential for adding the package's functionalities to your PHP project.

```bash
composer require tourze/enum-extra
```

--------------------------------

### Generate Select Options

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Demonstrates the usage of the genOptions() method to convert enum cases into an array of options suitable for UI select components.

```php
$options = Status::genOptions();
```

--------------------------------

### SelectDataFetcher Interface

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Defines the SelectDataFetcher interface, standardizing the process of fetching data specifically for select components, ensuring consistent data retrieval.

```apidoc
interface SelectDataFetcher
{
    public function genSelectData(): iterable;
}
```

--------------------------------

### BoolEnum Implementation

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Provides a ready-to-use BoolEnum implementation with helper methods like toBool() for converting the enum case to a boolean value and genBoolOptions() for generating boolean select options.

```php
use Tourze\EnumExtra\BoolEnum;

$value = BoolEnum::YES;
$boolValue = $value->toBool(); // true

// Generate boolean options
$options = BoolEnum::genBoolOptions();
// Result: [['label' => '是', 'text' => '是', 'value' => true, 'name' => '是'], ...]
```

--------------------------------

### Selectable Interface

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Defines the Selectable interface, providing static methods to generate collections of select options from enum cases, often used for UI dropdowns.

```apidoc
interface Selectable
{
    public static function genOptions(): array;
}
```

--------------------------------

### PHP Enum Definition and Usage

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Demonstrates defining a PHP enum that implements Labelable, Itemable, and Selectable interfaces, along with basic usage for generating select options and converting enum cases to arrays.

```php
use Tourze\EnumExtra\Itemable;
use Tourze\EnumExtra\ItemTrait;
use Tourze\EnumExtra\Labelable;
use Tourze\EnumExtra\Selectable;
use Tourze\EnumExtra\SelectTrait;

enum Status: string implements Labelable, Itemable, Selectable
{
    use ItemTrait;
    use SelectTrait;

    case ACTIVE = 'active';
    case INACTIVE = 'inactive';

    public function getLabel(): string
    {
        return match($this) {
            self::ACTIVE => 'Active',
            self::INACTIVE => 'Inactive',
        };
    }
}

// Generate select options
$options = Status::genOptions();
// Result: [['label' => 'Active', 'text' => 'Active', 'value' => 'active', 'name' => 'Active'], ...]

// Convert single case to array
$array = Status::ACTIVE->toArray();
// Result: ['value' => 'active', 'label' => 'Active']
```

--------------------------------

### Labelable Interface

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Defines the Labelable interface, which requires implementing classes to provide a getLabel() method for returning a human-readable string representation of an enum case.

```apidoc
interface Labelable
{
    public function getLabel(): string;
}
```

--------------------------------

### TreeDataFetcher Interface

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Defines the TreeDataFetcher interface, which outlines methods for generating hierarchical tree data structures from enum cases or related data.

```apidoc
interface TreeDataFetcher
{
    public function genTreeData(): array;
}
```

--------------------------------

### Filter Select Options via Environment

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Shows how to filter enum select options based on environment variables. Setting `enum-display:{enum}-{value}` to false in the environment will exclude that specific enum case from generated options.

```php
// In your .env file or server configuration
// $_ENV['enum-display:App\\Enums\\Status-inactive'] = false;

// Now Status::genOptions() will exclude the INACTIVE option
```

--------------------------------

### Enum Array Conversion

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Illustrates converting individual enum cases into a simple associative array format, typically containing 'value' and 'label' keys, useful for serialization or data transfer.

```php
$array = Status::ACTIVE->toArray();
// Result: ['value' => 'active', 'label' => 'Active']
```

--------------------------------

### Itemable Interface

Source: https://github.com/tourze/enum-extra/blob/master/README.md

Defines the Itemable interface, enabling enum cases to be converted into a structured array format suitable for select option items.

```apidoc
interface Itemable
{
    public function toSelectItem(): array;
}
```
