In the ever-evolving landscape of web development, PHP (PHP: Hypertext Preprocessor) remains a cornerstone scripting language. If you’re running WordPress sites or any web application, PHP likely plays a vital role in the backend. Its ubiquity is such that renowned websites like Facebook and Wikipedia are built using PHP, contributing to its enduring popularity. Moreover, WordPress, powering a staggering 40% of the web, relies heavily on PHP. In this comprehensive guide, we will delve into the importance of keeping your PHP version up-to-date and explore the key reasons behind this necessity.
PHP, or PHP: Hypertext Preprocessor, is a versatile, open-source scripting language predominantly used in web development. It serves as the bedrock for creating dynamic web pages, handling databases, and executing server-side scripts. Notably, PHP’s widespread usage extends to some of the largest websites on the internet. It is not only robust but also freely available, making it an accessible choice for developers worldwide.
As of the time of writing, PHP has evolved to version 8.2, showcasing the dynamic nature of this language. The PHP Foundation is committed to actively supporting this version until December 8, 2025, with an additional year of security updates. Staying informed about the latest PHP version is crucial for developers looking to harness its full potential.
In the realm of technology, updates and upgrades are ubiquitous. Just as your cell phone regularly receives updates and your favorite computer games receive patches, PHP undergoes version updates. Each new iteration of PHP brings forth novel features, carefully planned and implemented by the language’s maintainers. The availability of multiple PHP versions facilitates seamless transitions for development teams seeking to embrace new features or migrate between major versions.
Now, let’s delve into the crux of the matter: why is it imperative to use the latest PHP version? Below, we outline several compelling reasons.
The evolution of PHP has ushered in a plethora of new features, particularly in recent years, enhancing its power and capabilities. As the adoption of PHP for web development continues to surge, developers have access to top-notch features that rival those of other powerful programming languages. Failing to keep pace with the latest PHP version means missing out on these innovative features, potentially hampering your web development projects.
The hallmark of sustainable software is its continuous improvement and refinement. Frequent and consistent updates are essential to address bugs and vulnerabilities swiftly and effectively. By staying current with the latest PHP version, you ensure a stable and secure development environment, reaping the full benefits of the language’s feature set.
In an era fraught with cybersecurity threats, prioritizing the security of your web applications is paramount. Security issues emerge over time, necessitating prompt and robust solutions. Utilizing the latest PHP version guarantees access to the most recent security updates and patches. While older PHP versions may offer limited support beyond their “end of life” status, the safest choice is undeniably the version actively maintained by the PHP Foundation.
To provide a comprehensive perspective, let’s examine the evolution of PHP versions, highlighting key features and release dates:
PHP 8.2 (November 24, 2022)
PHP 8.1 (Current Version as of November 25, 2021)
PHP 8.0 (November 26, 2020)

It’s essential to note that PHP 6 never materialized. Originally planned, PHP 6 was abandoned, and the subsequent release following PHP 5.6 was branded as PHP 7.x. This version jump aimed to mitigate confusion between the abandoned PHP 6 and the forthcoming release.
For those with historical curiosity, PHP versions dating back to PHP 1 are available for download on the PHP museum website.
Before embarking on any updates, it’s essential to ascertain your current PHP version. There are several methods to achieve this:
1. Command Line:
php -vto obtain the active PHP CLI version. Please note that this may differ from the version running on the server, responsible for serving web requests.
