ASP.NET vs PHP: What's the Difference? Meaning and Use Cases Explained!

This time, we'll explain in detail which language you should choose when starting to learn web programming, and which is currently the better choice between ASP.NET and PHP!

1. What Are ASP.NET and PHP

Let's compare ASP.NET and PHP based on the following 7 criteria to see which one comes out on top.

1. Cost
2. Scalability
3. Community support
4. Supporting tools
5. Ease of learning
6. Popularity

1.1. What Is ASP.NET

ASP.NET is an open-source web framework created by Microsoft for building modern web apps and services that run on macOS, Linux, Windows, and Docker.

1.2. What Is PHP

PHP (a recursive acronym for "PHP: Hypertext Preprocessor") is a widely used, open-source, general-purpose scripting language that's especially well suited for web development. It can also be embedded directly into HTML.

1.3. Web3.0

Web3.0 is also known as the "next-generation internet."

2. Cost Differences Between ASP.NET and PHP

Next, let's look at the cost differences.

PHP is completely free and runs without issue on a variety of operating systems. It also works with many IDE environments, both paid and free.

ASP.NET, on the other hand, is a Microsoft product and therefore comes at a cost. There's also a practical issue you'll run into if you choose ASP.NET: it only runs on PCs/laptops running Windows. On top of that, renting a Windows server has in recent years often cost more than renting an equivalent Linux server.

If you're not used to programming, using ASP.NET itself costs nothing, but if you want to work professionally in this language, you'll also need to consider purchasing a Visual Studio license.

3. Scalability of ASP.NET and PHP

Both PHP and ASP.NET are highly scalable. A classic example is two famous social networks — Facebook (built with PHP) and MySpace (built with ASP.NET). This shows that both languages offer equal scalability.

It's a tie on this point.

4. Usability of ASP.NET and PHP

Website performance is evaluated based on how the source code, database, and server interact with each other.

Applications built with PHP mostly follow the LAMP principle — that is, Linux (operating system), Apache (server), MySQL (database), and PHP (programming language). The LAMP architecture is extremely popular in web development and is optimized for performance.

There isn't a huge structural difference in how PHP with MySQL and ASP.NET with MSSQL operate. However, many tests have shown that ext4-formatted Linux outperforms NTFS-formatted Windows.

PHP also tends to run better on shared hosting.

5. Programming Tools (Tools and Editors)

Many PHP programmers prefer to compile their code using simple text-editor tools like VIM, Notepad, or Sublime Text. If you want a built-in tool outside of an IDE, PHP also has its own dedicated tool, Eclipse.

ASP.NET is also supported by most IDEs, but it works within the Microsoft Visual Studio environment — a paid development tool that's powerful, versatile, and highly customizable.

6. Which Language Is Easier to Learn?

ASP.NET is programmed in C#, which was created based on C — a programming language that's fairly difficult even for professional programmers. That makes ASP.NET an extremely tough language for beginners to pick up. PHP, by contrast, is easy to learn — you can pick it up through self-study at home or by attending a specialized training program.

7. Popularity of ASP.NET and PHP

GitHub, which hosts around 2.2 million projects, ranks programming languages based on the number of active projects. Here's GitHut's top 16 table.

Even so, PHP comes out on top here.

8. Conclusion

PHP is the most widely used, popular language on the internet, supporting developers across many applications. Its community is large and freely accessible on the web. PHP is also easy to learn, so developers can get up and running in less time. Another difference is that PHP combines a programming language with a web framework, whereas ASP.NET is simply an application framework — and PHP is an open-source platform.

The ASP.NET framework comes with an impressively rich set of libraries. Thanks to its many built-in features, developers can build websites using built-in drag-and-drop functionality. All of these qualities come with a price tag in the form of license fees. PHP doesn't offer the option to work with a widely used web framework the way ASP.NET does. Programmers can write code in any language within the ASP.NET ecosystem, such as C#, Visual Basic (VB), or F#. With PHP, however, programmers don't have that same option. In this way, PHP gives developers the flexibility to build applications by choosing from a variety of web frameworks.

Both ASP.NET and PHP work efficiently once you factor in your business case and the feature set you need. Both ASP.NET and PHP have their own strengths and weaknesses. Which technology you choose ultimately comes down to your developers' skills and your business requirements.
