Misunderstandings in converting php to golang

With the popularity of golang, many developers have begun to consider migrating their PHP projects to golang. Although golang has the advantages of high efficiency, scalability and strong concurrency performance, many developers will fall into some misunderstandings during the transfer process. This article will introduce some misunderstandings that PHP developers may encounter when moving to golang to help them better adapt to the new language and environment.

Myth 1: Golang is similar to the PHP language

Many PHP developers think that golang is very similar to the PHP language, so they think it will be easy to learn golang. However, this is a very wrong idea. Although they are both scripting languages, golang is a statically typed programming language with unique syntax, type system and specifications.

The syntax of golang is completely different from the php language. In the PHP language, both variable declarations and function declarations use the $ symbol as a prefix, while Golang uses the var keyword. In addition, golang uses curly braces to represent code blocks, while php uses curly braces. The writing order of many keywords in golang is also different from that in php. Developers need to learn some knowledge in this area by studying the golang manual.

Myth 2: Golang has no classes

Compared with PHP, Golang lacks the concept of classes, which is a huge change for PHP developers. Golang is composed of interfaces and structures. A structure is a composite type that combines different fields and data types. An interface is a contract that describes the behavior of a structure's methods.

Although golang uses a different construction method, many ideas and concepts still apply when writing object-oriented programming. For example, a structure can act as a class and contain data and methods, and an interface can be used to implement type behavior. It takes some time and effort to understand golang's object-oriented programming scheme, but the process is not scary.

Myth 3: Golang does not have generics

In the PHP language, developers are accustomed to using generic types, such as arrays and objects, to handle different types of data. However, in golang, there is no support for generics. Although this seems cumbersome, golang solves this problem through interfaces and type assertions. Developers can use the interface{} interface to achieve flexible use of types. When an interface{} data type is received, a type assertion can be used to convert it to the actual type expected.

Myth 4: Golang is unstable

Many PHP developers think that golang is an unstable language that is still in the development stage because they know little about golang. However, golang is one of the leading programming languages ​​developed by Google and is widely used in cloud computing and microservices environments. At the same time, due to the unique nature of golang, it is considered more conducive to building high-performance and scalable applications than other languages.

It is undeniable that the development of golang is still very active. There will be some changes in API and system architecture, but the project code will basically not be affected in any way. There is still great potential for the development and use of golang, especially for applications that require high concurrency and high reliability.

Myth 5: Golang has no ecosystem

Compared with PHP, golang has a more powerful ecosystem and high-quality third-party libraries. In golang language, many features are well solved. For example, golang's database access library and network library are comparable to PHP's database access and network library. In addition, golang has rich community resources that can help developers become better familiar with the language and environment.

Conclusion

As a PHP developer, moving to golang language requires adapting to new syntax, type system and specifications. However, many PHP developers are hindered by some wrong ideas. By understanding golang's unique features and development prospects, developers can better master this leading programming language and application architecture. This will enable them to switch to the Golang language faster and gain tremendous value in future software development.
