  public static function sys_stat_calculate() {

    static::$memoryStart = memory_get_usage(true);
    static::$timeLastOperation = microtime(true);

It seems like microtime(true) can also be of type string. However, the property $timeLastOperation is declared as type double. Maybe add an additional type check?

$rate was never initialized. Although not strictly required by PHP, it is generally a good practice to add $rate = array(); before regardless.

    $rate[RES_CRYSTAL] = $config->rpg_exchange_crystal / $config->rpg_exchange_metal;
    $rate[RES_DEUTERIUM] = $config->rpg_exchange_deuterium / $config->rpg_exchange_metal;
