<?php
    public function generateRandomToken(int $length = 32): string
    {
        $chars = str_split('abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789');
        $len_chars = count($chars);

It seems like $chars can also be of type true; however, parameter $value of count() does only seem to accept Countable|array, maybe add an additional type check?

        $token = '';

        for ($i = 0; $i < $length; $i++) {
            $token .= $chars[mt_rand(0, $len_chars - 1)];
        }

        # Number of 32 char chunks
        $chunks = ceil(strlen($token) / 32);
        $md5token = '';

        # Run each chunk through md5
        for ($i = 1; $i <= $chunks; $i++) {
            $md5token .= md5(substr($token, $i * 32 - 32, 32));
        }

        # Trim the token to the required length
        return substr($md5token, 0, $length);
    }
