Php design mode prototype mode, design mode prototype _ PHP Tutorial

Php design mode prototype and design mode prototype. The prototype of the php design mode is similar to that of the engineering mode. it is used to create objects. Different from the implementation of the engineering model, the prototype mode is to first create a php design mode prototype mode, the design mode prototype

Similar to the engineering mode, the prototype mode is used to create objects.

Unlike the implementation of the engineering mode, the prototype mode creates a prototype object first, and then clone the prototype object to create a new object. This removes the need for repeated primitive operations during class creation.

The prototype mode applies to the creation of large objects. Creating a large object requires a great deal of overhead. if a new object consumes a lot each time, the prototype only requires memory copy.
