PHP updates in focus: all versions, deadlines and end of support at a glance

PHP, the dynamic and versatile scripting language, is an indispensable tool for the development of modern web applications. With regular updates and new versions, the PHP community keeps its language up to date to improve performance, security and functionality.

In this article, we take a comprehensive look at the current state of PHP, in particular the latest developments and future challenges. Find out which versions are currently in use, what support deadlines are coming up and how we can help you future-proof your projects.

Why updates in the PHP language are important

PHP updates are essential for the security, stability and performance of web applications. One of the main reasons for regular updates is to eliminate security vulnerabilities. As PHP is one of the most widely used programming languages on the web, potential security risks cannot be neglected. With regular updates, you can close security gaps discovered by the community or security researchers and thus reduce the vulnerability of web applications to attacks such as SQL injection or cross-site scripting.

In addition, updates improve the stability of the language by including bug fixes and performance improvements. Bugs in the PHP language can lead to unexpected behavior of web applications and potentially impact operations. By installing updates, you can fix such bugs and increase the reliability of your applications.
Another important aspect in favor of PHP updates is the support of new functions and technologies. Each update usually introduces new features that help you and your development team to write more efficient and modern code.

The life cycle of a PHP version using the example of PHP 8.1

However, PHP versions do not live forever. The life cycles of each version are clearly defined and follow a precise schedule. At the beginning of each version branch, a stable version is released, which is then fully supported for two years. PHP 8.1, for example, was released in November 2021 and fully supported until November 2023. Developers therefore received regular updates with bug fixes and security patches until last year.

At the end of the two-year phase of active support, another phase will begin in which it will only be supported for critical security issues. PHP 8.1 is currently in exactly this phase.

In November of this year, version 8.1 of PHP will reach the end of its life cycle after three years. After that, no more updates or security patches will be released for this version.

For you, this means it's high time for an update!

The price of procrastination: Why companies procrastinate on PHP updates

Nevertheless, many companies are reluctant to carry out precisely these updates. According to a survey conducted by W3Tech in March 2024, 16% of the companies surveyed are still using PHP 5, even though no security updates have been installed since 2018.

But why is that? The dangers of outdated versions are widely known. Nevertheless, companies often lack the capacity to carry out an update themselves. The urgency is underestimated and suddenly, years later, the website is outdated and insecure.
Companies are now faced with an even greater challenge, as updating outdated websites is not only time-consuming, but also involves considerable costs.

To avoid these problems, we recommend a timely update.

What are your advantages?

Remember that updates are not just work. They offer benefits to both your website and your developers that should not be ignored:

Security

The security of your website is crucial, especially if sensitive data is stored in the database or in files on your server. As soon as you use an outdated version of PHP, you expose yourself to a considerable risk. Hackers or malware could attack and infect your server.

Performance

Every PHP update contributes to the optimization of your website. Not only does it improve your search engine ranking, but also the customer experience. This allows you to keep your visitors on your website for longer and even increase your conversion rates.

Tip: On PHPBenchmarks.com you can see by how many percentage points the last updates have improved.

New features

Every version, even small iterations, brings valuable innovations for developers and therefore your company.

One example of this is PHP 8, which makes it easier for developers to write code and reduces susceptibility to errors.
