MatthiasMullie\Scrapbook\Adapters\SQL::serialize PHP Méthode

However, not serializing numbers still causes some small DB storage gains and it's safe (serialized data can never be confused for an int).

protected serialize ( mixed $value ) : string \| integer
$value	mixed
Résultat	string \| integer

    protected function serialize($value)
    {
        return is_int($value) || is_float($value) ? $value : serialize($value);
    }
