Stringy - Get and manipulate $charsArray at runtime

Stringy - charsArray.php

<?php

require './vendor/autoload.php';

use Stringy\Stringy;


class MyStringy extends Stringy {

    public $managedCharsArray;

    protected function charsArray()
    {
        if (isset($this->managedCharsArray)) {
            return $this->managedCharsArray;
        }

        return parent::charsArray();
    }

    public function getDefaultCharsArray()
    {
        return parent::charsArray();
    }
}


$stringy = new MyStringy('ééé foo', 'UTF-8');


$charsArray = $stringy->getDefaultCharsArray();

$charsArray = array_merge($charsArray, [
    'bar' => ['foo']
]);

$stringy->managedCharsArray = $charsArray;


$result = (string) $stringy->toAscii();

var_dump($result); // "eee bar"

Caveat: because regular Stringy objects are immutable and methods return new instances, the result of toAscii() gets back the default charsArray. This could be circumvented by using some global state.
