From your first line of code, to your first day on the job — Educative has you covered. Join 2M+ developers learning in-demand programming skills.

Key takeaways:

  • PHP and JavaScript are both top contenders for web development. Each has unique strengths, so the choice should depend on your goals and project needs.

  • Learning both PHP and JavaScript can elevate your development skills by bridging the gap between back-end processing (PHP) and front-end interactivity (JavaScript).

  • PHP excels in server-side tasks like content management systems (WordPress) and e-commerce platforms, while JavaScript powers interactive front-end designs, real-time applications, and full stack solutions with Node.js.

Choosing between PHP and JavaScript is a common dilemma when it comes to web development.

PHP dominates server-side development, powering platforms like WordPress, while JavaScript drives interactive front-end experiences and even full stack applications with Node.js.

But which one should you learn first?

And how do they compare in real-world development?

In this blog, we’ll break down the strengths and weaknesses of PHP and JavaScript, explore their use cases, and help you decide which language aligns with your goals.

What is PHP?#

PHP stands for “Hypertext Preprocessor,” though it originally stood for “Personal Home Page.” As the language evolved, the meaning was changed to reflect its broader functionality. It is a widely used scripting language designed for server-side development. Introduced in 1994 by Rasmus Lerdorf, PHP has been one of the top choices for many developers because it processes information on the backend and then sends the processed data to the browser as plain HTML.

Thanks to its server-side capabilities, PHP is a popular choice for developing dynamic web pages and applications that require data manipulation, such as content management systems or e-commerce platforms.

PHP is highly flexible and platform-independent, seamlessly integrating with databases like MySQL and PostgreSQL. Its ability to generate dynamic content on the server makes it ideal for CMS platforms and e-commerce applications. Because of this, it may function on a variety of operating systems, including Windows, Linux, and macOS. PHP’s extensive ecosystem, various built-in features, and an excellent community have made it possible for modern web solutions, ranging from WordPress to massive business apps.

Advantages of PHP#

  • PHP is an open-source programming language, which means users and developers can modify its code.

  • PHP is a platform-independent programming language, meaning that it’s suitable for Mac, Windows, Unix, and Linux environments.

  • PHP is easy to learn. With the right content and guidance, you can learn PHP very quickly.

  • PHP boasts a robust and active community that offers extensive support, resources, and contributions to its ecosystem.

Disadvantages of PHP#

  • While PHP powers large, content-heavy platforms like WordPress, scaling massive applications requires careful architectural planning. PHP’s monolithic nature can make scaling complex applications more challenging compared to modern microservices-based stacks.

  • Since PHP is widely used in CMS platforms and open-source projects, outdated code and poorly maintained plugins can introduce security risks if not properly managed.

  • Due to scalability and maintenance concerns, PHP might not be the best choice for extremely large and complex applications.

  • PHP isn’t the best option for heavy computational tasks or situations where real-time performance is essential, like intense graphic design or image processing.

What is JavaScript?#

JavaScript, often referred to as JS, is a high-level programming language renowned for its role in web development. It was introduced in 1995 by Netscape as a front-end language to help create interactive web pages, and it serves its purpose very well. People usually think that JavaScript is a front-end language, but that’s not entirely true.

JavaScript is no longer just a front-end language. With Node.js, it now powers full stack applications, making it one of the most versatile languages in modern development. Coupled with a vast ecosystem, myriad libraries, and frameworks like React, Angular, and Vue.js, JavaScript stands as one of the most versatile and widely used programming languages in the world today.

Advantages of Javascript#

  • JavaScript enables dynamic content, providing users with interactive web pages and a richer user experience. Developers can seamlessly implement features like animations, form validations, and responsive designs using JavaScript.

  • Almost all modern browsers support JavaScript, meaning most users can access JavaScript-based applications without additional requirements.

  • JavaScript runs in the client’s browser, reducing the load on the server and providing quicker response times.

  • With platforms like Node.js, JavaScript is not limited to the browser. It can be used for server-side development, making full-stack development possible with one language.

  • A vast array of frameworks, libraries, and tools are available—such as React, Angular, and Vue.js for front-end development and Express.js for the back-end—which accelerates development and offers solutions for various needs.

Disadvantages of Javascript#

  • JavaScript’s code is visible to users so they can use it for malicious purposes, and it can put a toll on the security of your web application.

  • Debugging JavaScript can be challenging due to browser differences and its asynchronous, event-driven nature, which can lead to complex execution flows.

  • Different browsers implement JavaScript in slightly different ways. This means that developers had to write extra code to ensure functionality across all browsers.

  • JavaScript is an interpreted language that might not run as fast as compiled languages.

  • JavaScript runs in a single thread. While there are ways around this limitation, such as using Web Workers, it’s not as straightforward as multi-threaded programming in other languages.
