Enum

This package goal is to provide a complete solution to lack a long time php weakness : it do not have any enum support. This will change with php 8 enums proposition. In the mean time we still a support for this allowing us to generate generic and extendable applications (instead of have singletons sql tables..).

You will be able to use enums in any project using a simple definition, take a look at example Basic or a more sophisticated Example

Installation

Via Composer

$ composer require kwaadpepper/enum

---

Usage

All enum have two properties : label and value, only value has to be unique. Each enum can have multiple options all written on class comment as static methods, these have to be unique !

• On Any project, take a look on examples to create an enum class.

1. Invoke an enum value

   Days::mon()
   

2. Compare enums

   Days::mon()->equals(Days::tue()) // false
   Days::mon()->equals(Days::mon()) // true
   Days::mon()->value === Days::tue()->value // false
   Days::mon()->value === Days::mon()->value // true
   

3. Print an enum

   echo Days::mon(); // 2
   echo Days::tue(); // 4
   echo Days::mon()->label; // Monday
   

   As you can see enum implements the __toString method which you can override to display the label instead of the value. This default behavior is set like this for a better behavior in laravel.

4. Serialise an enum

   echo json_encode(Days::mon()); // {"label":"Monday","value":2}
   

   Enums implement the JsonSerializable interface

• On a Laravel project you can use enums in multiple ways

1. As a property

   // Add theses to your model
    use CastsEnums;
    protected $enumCasts = [
        'day' => Days::class
    ];
   

   This will allow you model to store an enum in database using its value, and then cast the property to an enum when accessing it

2. As a route parameter

   Define a route like the following

   Route::get('/days/{day}', function (Days $day) {
            return response()->json([$day]);
        })->middleware('bindings');
    // OR
    Route::get('/days/{day}', [DayController::class, 'getDay']);
   

   Then on your controller for the DayController example

   public function getDay(Request $request, Day $day) {
       return response()->json([$day]);
   }
   

3. As a request parameter using validation

   Take a look at this request example.

   new EnumIsValidRule(Days::class)
   

   It use EnumIsValidRule to validate the parameter as being a valid enum value.

   Note that you may still have to cast your parameter to int if your enum value is an int, as enum check is strict

4. As a model primary Key

   Take a look at unit test using the Report enum class from tests
