Enums in PHP and Java

This is mainly for my personal reference. Enums are quite useful to use in projects and save typing and make sure Strings/Integers match, because it's not uncommon that, for example, you type "list" instead of the expected word "List" or misspell things and other such tirivial issues.

PHP:

<?php

//PHP has no native Enum type so you need to manipulate
//a normal class to work how you want it to
final class Season
{
    //class constants are inherantly public and static
    const SPRING = 'Spring';
    const SUMMER = 'Summer';

    const AUTUMN = 'Autumn';

    const WINTER = 'Winter';

    public function __toString()
    {

        //default return
        return self::SPRING;
    }
}

//Test the enum... prints out Spring.
echo ( new Season() );

//And if I wanted to choose just Summer
echo Season::SUMMER;

Java:

public enum Season {
    //define the values
    SPRING, SUMMER, AUTUMN, WINTER;
   

    //for extra useability have it return a string of the chosen enum when needed
    @Override
    public String toString(){
        switch(this){
            case SPRING: return "Spring";
            case SUMMER: return "Summer";
            case AUTUMN: return "Autumn";
            case WINTER: return "Winter";
            default: return "Spring";
        }
    }
}

//usage - prints out Summer
System.out.println( Season.SUMMER );
