Uncovering the Major Differences Between PHP 7 and PHP 8

PHP is one of the most popular programming languages used to create dynamic websites and web applications. With the release of PHP 7 in 2015, developers have seen a significant improvement in performance and security. Now, with the upcoming release of PHP 8, developers are expecting even more improvements. In this article, we will discuss the differences between PHP 7 and PHP 8.


The most notable difference between PHP 7 and PHP 8 is the speed. PHP 8 is expected to be twice as fast as PHP 7, making it a great choice for applications that require high performance. Additionally, PHP 8 will include new features such as JIT (Just-in-Time) compilation, which will further improve performance.

Another major difference between the two versions is the syntax. PHP 8 will introduce new syntax features such as union types, attributes, and match expressions. These features will make it easier for developers to write code that is more concise and easier to read.

Content Security Policy

In terms of security, PHP 8 will include a new type of security called “Content Security Policy” (CSP). This feature will help protect websites from malicious attacks by preventing malicious code from being executed on the server. Additionally, PHP 8 will also include a new type of encryption called Argon2i, which is more secure than the current encryption algorithms used in PHP 7.

Zend Garbage Collector

Finally, PHP 8 will also include a new type of garbage collection called “Zend Garbage Collector” (ZGC). This feature will help reduce memory usage and improve performance by automatically freeing up memory that is no longer needed.

Overall, there are many differences between PHP 7 and PHP 8 that make it an attractive choice for developers looking for improved performance and security. With its improved speed, new syntax features, and enhanced security measures, PHP 8 is sure to be a great choice for web development projects.
