Analyze the advantages and disadvantages of PHP object-oriented programming

phpObject-oriented programming is a very practical and popular design pattern, and naturally it has become a technology that beginners must firmly master. Let’s talk about its advantages and disadvantages for programming.

1. Using object-oriented thinking for development has the following advantages:
1. Easy to maintain
The structure designed using object-oriented thinking has high readability. Due to the inherited Even if the requirements change, the maintenance will only be on local modules, so maintenance is very convenient and low-cost.
2. High quality
During design, existing classes that have been tested in the field of previous projects can be reused to make the system meet business needs and have high quality.
3. High efficiency
During software development, things in the real world are abstracted and classes are generated according to the needs of the design. Using this method to solve problems is close to daily life and natural way of thinking, which will inevitably improve the efficiency and quality of software development.
4. Easy to Expand
Due to the characteristics of inheritance, encapsulation, and polymorphism, a system structure with high cohesion and low coupling is naturally designed, making the system more flexible, easier to expand, and lower in cost.

2. Advantages and Disadvantages of OO Method

Advantages:

(1) It is a brand-new system analysis and design method (object, class, structure properties, methods).

(2) Suitable for the development of various information systems.

(3) Achieving direct conversion from description of the objective world to software structure, greatly reducing the amount of subsequent software development.

(4) The development work has high reusability and inheritance, reducing the workload of repeated work.

(5) Shortened the development cycle.

Disadvantages:

(1) A certain software support environment is required.

(2) It is not suitable for large-scale MIS development. If there is a lack of overall system design division, it will easily lead to problems such as unreasonable system structure and imbalanced relationship between various parts.

(3) It can only be classified and sorted on the basis of existing business, and cannot be straightened out and optimized from the perspective of scientific management.

(4) It is not easy for beginners to accept and learn.

Object-oriented methodology naturally links analysis, design and implementation. Although object-oriented design does not depend on a specific implementation environment in principle, the implementation results and implementation costs depend to a large extent on the implementation environment. Therefore, object-oriented programming languages, development environments and class libraries that directly support the object-oriented design paradigm are very important for object-oriented implementation.
In order to smoothly transform the object-oriented design results into an object-oriented program, you should first choose an appropriate programming language. Object-oriented programming languages ​​are suitable for realizing object-oriented design results. In fact, object-oriented programming languages ​​with convenient development environments and rich class libraries are the best choice for implementing object-oriented design.
Good programming style is particularly important for object-oriented implementation. It includes both traditional programming style guidelines and some new guidelines that are compatible with the characteristics of object-oriented methods.
Object-oriented methodology uses unique concepts and completes software development work. Therefore, when testing object-oriented programs, in addition to inheriting traditional testing techniques, new tests that are adapted to the characteristics of object-oriented programs must also be studied. technology. There is still a lot of research work that needs to be done in this area, and it has gradually become a new hot topic in the software engineering community at home and abroad.
