As an experienced backend developer, PHP has played a significant role in my career. However, the tech landscape is ever-changing, and we must always be prepared for new challenges. So, if PHP suddenly disappeared today, which backend language would I choose to replace it? Here are my candid insights.

1. Golang
First and foremost, I would undoubtedly choose Golang (Go language). Why? Because Golang not only offers superior performance, but the development experience is exceptional. Compared to PHP, Golang’s concurrency handling is on a completely different level. Writing Golang code feels like a delightful journey, free from the cumbersome configurations and endless debugging sessions.

Golang’s standard library is robust and can meet almost all of your development needs. Its “Bring your own” approach is perfect for developers who despise being constrained by frameworks. You don’t need to create separate files for every struct, and error handling is more straightforward and transparent. In short, Golang lets you focus on the code itself rather than being bogged down by various quirky framework issues.

2. Python
Python is another strong contender. Its syntax is clean and straightforward, with almost no learning curve. If you’re tired of PHP’s inconsistent function names and odd syntax, Python will feel like a breath of fresh air. Not to mention, Python’s powerful libraries in data science and machine learning are like adding wings to a tiger.

However, Python’s performance doesn’t quite match up to Golang. But for most web applications, performance isn’t a deal-breaker. Frameworks like Django and Flask offer rich functionalities, making development highly efficient. If you want to get up and running quickly and dive into actual development, Python is an excellent choice.

3. Node.js
Node.js is a love-hate relationship for me. JavaScript in the backend does feel a bit awkward, but there’s no denying that Node.js excels in handling I/O-intensive tasks. You can write both frontend and backend code in the same language, significantly boosting development efficiency for some projects.

However, the Node.js ecosystem is somewhat chaotic, with npm filled with libraries of varying quality. You might spend a lot of time debugging and finding the right libraries. But if you’re already a JavaScript expert, Node.js is a natural choice.

4. C#
For developers with a Windows background, C# and .NET are safe bets. C# is a powerful and type-safe language with high performance and rich framework support. Especially with the introduction of .NET Core, C#’s cross-platform capabilities have significantly improved, making it run well on Linux servers too.

However, C# has a relatively steep learning curve, and its ecosystem is still largely geared towards enterprise applications. If you love tinkering with new technologies, C# might not be the ideal choice.

5. Rust
Finally, I have to mention Rust. Rust is renowned for its exceptional performance and memory safety. Although it has a steeper learning curve, for developers seeking high performance and security, Rust is an excellent choice. The Rust community is very active, and the quality of open-source projects is high, making it worth delving into.

However, Rust’s ecosystem is still maturing, and the selection of frameworks and libraries is relatively limited. If you’re willing to invest time in exploring and learning, Rust will provide an unparalleled development experience.

Conclusion
Regardless of which development language you choose, a good development environment is essential. Here, I recommend ServBay. ServBay is the next-generation web development environment, offering a quick, dependency-free, and non-intrusive installation solution for PHP/Node.js development environments. In just 3 minutes, you can have a complete development environment, including web servers, databases, email, DNS, and common tools, all without needing Docker or source code compilation. ServBay is compatible with macOS 12 and later versions, supporting both arm64 and x86_64 architectures, providing a high-performance and resource-efficient development platform. Try ServBay and boost your development efficiency.

No matter which language you choose, the key is to maintain an open mind and a passion for continuous learning. The tech world is ever-changing, and only by adapting and progressing can we remain undefeated in this industry.
