This article mainly introduces how to use PHP to develop applications elegantly. It is very detailed and has a certain reference value. Friends who are interested must read it!

Flow chart design

When we develop an application, the first time we should not think about how to code, the first thing we should do is to clarify the requirements, because solving the requirements is the value of an application.

As an old saying goes, work is not done by the east, even if you are tired to death. In many cases, we may not be able to understand the user's needs at first, or the user or product manager may not be able to state exactly what they really need at first. We have the responsibility and obligation to help product managers sort out their ideas, and what we need to do is to draw a flow chart to identify clear and clear needs, and never make it clear verbally, otherwise we will miss work in the future. Or when something goes wrong, the product manager will let you take the blame.

Interface design

As we said earlier, product managers may not know the features they want at first, or they may add other features in the future, so we need to make a reasonable interface design. The interface design here does not refer to the front and back end communication interface, but refers to the object-oriented interface. A reasonable interface design can make our program more robust and flexible. At the same time, it can also make our business clearer.

Good interface design allows us to add and modify functions with few changes to the code, but without interface design, or if the interface design is not clear, our code will become a pot of porridge, and you won't know where to spoon it.

The use of design patterns

Design patterns not only make the code more elegant, but most importantly, it makes the code more reusable.

By using design patterns, we can make our code highly cohesive and low-coupling, making it easier for us to change requirements and add new features.

Through design patterns such as dependency injection, our code will become more elegant and testing will become easier.

Use ORM to operate the database

Although ORM can have some impact on performance, the performance impact is negligible compared to the benefits it brings. By using ORM, we can make our code writing more concise and convenient.

The biggest advantage of using ORM is that it can save development time. After all, object-oriented coding is more easily accepted by programmers.

Using framework development

In the field of web development, no matter what language, there will be its own framework, even if some are not open source frameworks, even if some frameworks are unique to the company, they are also frameworks, and the biggest advantage of using a framework is to simplify the development process, avoid a lot of repetitive wheels, and make the code structure clearer.

By using frameworks, many low-level errors can be avoided, and many frameworks integrate a lot of useful scaffolding, which we can use directly out of the box. In today's time is money, the use of frameworks can greatly save development time, which undoubtedly saves a lot of money.

Integrated unit testing

An excellent project must be able to cope with all kinds of risks, and there must be few bug.

No one is perfect, and in order to minimize our errors, or to expose our errors as much as possible in the development phase, using an integrated testing framework such as PHPUnit is the best choice.
