php design mode prototype mode, design mode prototype

Prototype mode has a similar function to engineering mode, both are used to create objects.

Different from the implementation of the engineering mode, the prototype mode first creates a prototype object, and then Tonggu clones the prototype object to create a new object. This eliminates the need for repeated initialization operations when creating classes.

Prototype pattern is suitable for the creation of large objects. Creating a large object requires a lot of overhead. If it is new every time, it will consume a lot of money. The prototype mode only needs a memory copy.
