SplEnum
=======

[](#splenum)

Warning

PHP 8.1 introduced native Enumerations (Enums), providing a modern, more efficient approach. This package is intended for projects that rely on `SplEnum` and need backward compatibility or cannot upgrade to PHP 8.1+.

If possible, consider using PHP's native enums for improved type safety, performance, and maintainability.

This package is a polyfill for the now-unsupported `SplEnum` class, originally part of the [PECL SPL\_Types extension](http://pecl.php.net/package/SPL_Types).

By using this polyfill, you can emulate the `SplEnum` behavior in PHP without relying on the extension, which is no longer actively maintained.

The `SplEnum` class provides a way to create enumeration-like objects natively in PHP, offering a structured and type-safe way to work with predefined constant values.

Example
-------

[](#example)

```

```

The above example will output

```
6
Value '13' is not part of the enum Month

```

Class sypnosis
--------------

[](#class-sypnosis)

```
abstract class SplEnum
{
    /* Constants */
    const NULL __default = NULL ;

    /* Methods */
    SplType::__construct ([ mixed $initial_value ] )

    public array getConstList ([ bool $include_default = FALSE ] )

}
```
