When performing the project, it is recommended to instantiate a Class in the file where it is implemented

(Ex.: "classname.Class.php"),

causing it to be instantiated even without being used in the system at various times

OR

only when they need to access some method from it?

    Only create an object when using.

You should instantiate an object only when using, for example: A Car class where you need to store the card and use some method of it.

Class loading

But in your example you gave the idea of importing a class to your PHP file and really this is a problem since you will be loading items that at that time will not use, besides having to fill your include code.

For this second case, PHP has the spl_autoload_register, an Autoloading that already do all this service for you. I’ll leave the Autoloading documentation link below so you can get more in-depth about.
