What PHP Versions Does TYPO3 Support?

TYPO3 boasts an extended maintenance window, surpassing many other CMS options. However, for certain outdated PHP and TYPO3 versions, these maintenance periods are drawing to a close. If the software you depend on is nearing its "end-of-life" (EOL), it's crucial to contemplate your next moves to ensure the security and legal compliance of your websites. Through ELTS, TYPO3 provides support that extends beyond the LTS duration, offering a solution for your ongoing needs.

Key Statistics

Outdated software creates a sense of urgency for upgrades. According to W3Techs' November 2023 report, 47.3% of currently active websites are still operating on PHP version 7, posing potential vulnerabilities for thousands of sites. Specifically concerning TYPO3 CMS, a survey conducted by TYPO3 Version Statistics in September 2023 examined 229,000 TYPO3 websites.

The findings revealed that around 12.57% of these sites were using TYPO3 v8.7, an unsupported version that could pose risks to site owners. Additionally, 12.49% were running TYPO3 v9.5, which relies on an unsupported PHP version. Recognizing these risks, our TYPO3 digital agency partners strongly advise their clients to promptly update their sites for enhanced security and compliance.

Let's delve into the implications of these statistics.

What is meant by a "Supported Version"?

A "supported version" of software is officially backed by a team of developers who are prepared to assess and resolve bugs or security issues that may arise. This aspect is not only a reassuring factor or a desirable element for IT governance; it is also crucial for compliance with laws and regulations governing data privacy and security. Regulations such as GDPR mandate the use of up-to-date software.

In the context of open-source software, a supported version ensures that discovered bugs and security issues are promptly addressed. However, the ability to maintain numerous versions is inherently limited. As time progresses, older versions typically transition through a phase where updates are restricted to addressing only the most critical issues before eventually reaching the "End of Life" (EOL) stage.

The PHP community follows a similar trajectory, moving versions from an "Active Support" phase, where the version receives both bug fixes and security updates, to a "Security Fixes Only" phase, wherein only critical security issues are addressed.

For TYPO3 CMS, each new version undergoes a series of sprint releases to introduce new features, improvements, and deprecations. The launch of the Long Term Support (LTS) version initiates a three-year period of continuous support. During this LTS maintenance period, the TYPO3 Core Team issues regular bug-fix updates and security fixes as necessary, supporting two versions simultaneously—the current LTS release and its predecessor.

After this initial three-year support window, TYPO3 GmbH provides an Extended Long Term Support program for an additional three years, available through paid support. This extension increases the potential supported lifecycle of a TYPO3 site, maximizing the return on investment and affording companies the time to determine their next strategic steps.

Managing and aligning various software versions may be challenging. To simplify this process, here is a table illustrating the compatibility of TYPO3, PHP, and MySQL versions.

How to check the PHP Version of your TYPO3 Website?

Method - 1 Using TYPO3 Backend

To check the PHP version of your TYPO3 website Login to your TYPO3 Backend, from the Top right corner “System Information”.  Here, you will find all the essentials.

Method - 2 Without TYPO3 Backend

  • Step - 1: Create phpinfo.php file at your root directory
  • Step - 2 : Add below code


// Show all information, defaults to INFO_ALL
  • Step - 3 : run  the phpinfo.php file

Which PHP versions does TYPO3 support?

When examining the compatibility between TYPO3 and PHP versions, it becomes apparent that TYPO3 v9 and v10 no longer align with a supported PHP version.

For those operating a TYPO3 v10 site or an earlier version, it is imperative to transition to TYPO3 v12. Similarly, for those utilizing TYPO3 v11, it is advisable to start contemplating the next steps.
