php-enumeration

This small package can represent a enumeration field. For example in a database or an api.

Featureslist:

• inspired and mostly used for MySQL enum-fields or API enum-fields
• it is a simple string representation
• no other values are allow besides the defined in the class
• simple usage and easy to read
• no features a enum do not have to deal with
• with a default fallback value which will be used if no matching value exists in const´s
  • you can harden this object by throwing an exception in the getDefault-method

Install

Basic install via composer

composer require freshp/php-enumeration

Usage

Take a look in tests/fixtures to see a executable example.

Create a new object with:

1. public const´s which represent strings
2. implement the getDefault-method

Create an enumeration object

use FreshP\PhpEnumeration\Enum;

class EnumExample extends Enum
{
    public const TEST_CONSTANT = 'constant';
    public const TEST_DEFAULT = 'default';
    
    protected function getDefault(): string
    {
        return self::TEST_DEFAULT;
    }
}

use annotations for better ide support

use FreshP\PhpEnumeration\Enum;

/**
 * @method static self TEST_CONSTANT()
 * @method static self TEST_DEFAULT()
 */
class EnumExample extends Enum
...

make the data of the parent toArray-method public if you need to iterate over all options

class EnumExample extends Enum
{
...
    public static function listAllOptions(): array
    {
        return self::toArray();
    }
...

Use the enumeration object

1. create the object by static call

   $enum = EnumExample::TEST_CONSTANT();

2. create the object by normal initialization

   $enum = new EnumExample(EnumExample::TEST_CONSTANT);

3. create a default object (the value from the getDefault-method will be called)

   $enum = new EnumExample();

4. compare the object by using the __toString-method

   $enum->__toString() === EnumExample::TEST_CONSTANT

   or

   $enum->isEqual(EnumExample::TEST_CONSTANT())
