Is Php 8 Faster Than Php 7

PHP Programming

As a PHP developer, I’ve always been interested in the performance improvements that each new version of PHP brings. With the release of PHP 8, one of the questions on every developer’s mind is: Is PHP 8 faster than PHP 7? In this article, I will dive deep into the details and provide a personal commentary on the topic.


PHP is a popular server-side scripting language that powers a significant portion of the web. Performance is a critical aspect of any programming language, as it directly affects the user experience and the efficiency of the underlying infrastructure.

PHP 7 was a game-changer when it comes to performance improvements. It introduced the Zend Engine 3.0, which resulted in significant speed enhancements over its predecessor, PHP 5. The question now is whether PHP 8 can outperform its already impressive predecessor.

Comparing PHP 8 and PHP 7 Performance

Before diving into the performance improvements of PHP 8, it’s essential to understand the benchmarks used to measure its speed. The most commonly used benchmark is the PHPBench, which focuses on real-world scenarios and tests various aspects of the language.

PHP 8 introduces a Just-In-Time (JIT) compiler, which is a significant addition to the language. The JIT compiler can dynamically optimize and generate machine code at runtime, resulting in faster execution of PHP scripts. This feature alone has the potential to bring considerable performance improvements.

In addition to the JIT compiler, PHP 8 also introduces several other performance optimizations. These include improvements in the type system, better handling of call stack, faster error handling, and more efficient memory management. All these changes contribute to better overall performance.

Personal Commentary

Having tested PHP 8 extensively, I can confidently say that it does deliver on its promise of improved performance. In my experience, PHP 8 consistently outperforms PHP 7 in terms of execution time. The JIT compiler, in particular, makes a noticeable difference, especially in scenarios where code execution involves repetitive tasks.

However, it’s important to note that the performance gains offered by PHP 8 may vary depending on the specific use case. In some scenarios, the improvements may be marginal, while in others, they can be quite substantial. It’s always a good idea to benchmark your application before making any conclusions about the performance gains.


PHP 8 brings significant performance improvements over its predecessor, PHP 7. The introduction of the JIT compiler and other optimizations make PHP 8 a compelling upgrade for developers. While the performance gains may vary depending on the specific use case, overall, PHP 8 delivers faster execution times and improved efficiency.

As a PHP developer, upgrading to PHP 8 is a no-brainer. The improved performance not only enhances the user experience but also reduces server load and infrastructure costs. Embracing the latest version of PHP ensures that your applications are running on the most efficient and modern platform.

So, to answer the question: Is PHP 8 faster than PHP 7? Absolutely!
