将此数据存储在内存而不是数据库表中的性能是否不好?

I want to install a game on my site. The interaction takes a lot of jobs, mainly about moving the game's options to my site's admin option control pannel. To avoid the interaction job, I'm thinking to make a Class to store the options, and call the calss by Global.

Class Game_Vars{
var ...;
... ...;
}
Global $game_options;
if ( !isset( $game_options ) ) $game_options = new Game_vars();

By this way, the options won't be stored in database, and the Class.php will be loaded everytime when the game script is running. There are nearly 70 options, is this too heavy for performence?

    It depends on how static the data is, which tells you how easy is must be to change the data. If the data never changes and does not need an interface to change it, then there is nothing wrong with using a class and storing your data in memory. Otherwise, use a database to better manage the data (but fetch the data once from the database using a design pattern such as a Singleton or a single static variable).

    You will not run into any memory / hardware performance / efficiency issues when storing 70 data members of a class into memory on any semi-modern server. Especially since (as Pastor Bones points out) that regardless of which option you choose (database or file), all of the options will be loaded into memory at some point.
