To create a getter and setter, connect this trait to a class and declare a method inside the class with the name of your field. The name of the desired field must be prefixed with _gs_. The method must return an array with two keys: get and set, and the values must be anonymous functions. The first method will return the desired value, and the second will set that value. For example, you want to declare a $PropertyName field:

<?php
declare(ticks = 1);

namespace Program;

use GetterSetter\GetterSetter;
use IO\Console;

class Main
{
    use GetterSetter;

    private string $myprop = "";

    public function _gs_PropertyName() : array
    {return [
        Get => function() : string
        {
            return strtoupper($this->myprop);
        },
        Set => function(string $value) : void
        {
            $this->myprop = $value;
        }
    ];}

    public function __construct()
    {
        $this->PropertyName = "hello world";
        Console::WriteLine($this->PropertyName); // Result: "HELLO WORLD";
    }
}
