The PHP Foundation Turns 3: Review and Outlook

PHP is a server-side scripting language widely used for dynamic web application development (in French). It generates HTML content, interacts with databases, manages user sessions, and much more. Its syntax is relatively simple and its community is very active, which makes it a popular choice for developers.

The PHP Foundation: A Pillar for the Future of PHP

The PHP Foundation is a nonprofit organization created in 2021 to support the development and evolution of the PHP language. While PHP continues to play a central role in web development, the foundation's mission is to ensure its longevity by meeting growing maintenance and innovation needs.

Why a Foundation for PHP?

Although PHP is a widely adopted open-source language, its development has always relied on volunteer contributions. The PHP Foundation was created to bring organization and funding to:

• Ensure stability: by supporting the key developers who maintain the language and coordinating community efforts.
• Foster innovation: by driving the introduction of new features, performance improvements, and update management.
• Strengthen security: by running regular audits and responding quickly to vulnerabilities.

The PHP Foundation's Missions

The foundation plays a central role in the PHP ecosystem by:

• Providing financial support to the main contributors so they can work full time on the language.
• Managing the necessary infrastructure, such as testing tools, benchmarks, and documentation.
• Maintaining a clear and consistent roadmap for future PHP versions.
• Working closely with sponsors, companies, and the open-source community to keep development aligned with market needs, notably around the PSRs that structure interoperability in the PHP ecosystem (in French).

PHP: A Lasting Success

PHP remains one of the most widely used languages for web development today, with a major presence in the digital ecosystem. According to W3Techs, about 75% of websites with an identifiable server-side language run on PHP. WordPress alone powers more than 40% of the global web, which largely explains this dominance.

On the version side, adoption of PHP 8.x is progressing quickly. Packagist statistics show that PHP 8.1+ now represents the majority of active installations in the Composer ecosystem, a sign that the community is keeping pace with new releases.

These figures confirm PHP's reliability, performance, and adaptability, which keep it an essential choice for developers and companies around the world.

PHP Today

Efficience IT closely follows the evolution of PHP, notably through its PHP application modernization (in French) activities, and applauds the work of this foundation, which has a team of 10 engineers specialized in the language. Thanks to their expertise, backed by large companies, governments, and a vibrant community, PHP keeps growing and inspiring innovative projects.

Since 2021, three new PHP versions have been released: PHP 8.2, 8.3, and 8.4. Here is an overview of the main new features these versions brought, developed by the PHP Foundation team. The next milestone on the horizon is PHP 9.0 and the major changes to anticipate (in French).

The latest PHP updates introduce innovative features that improve the language's performance and flexibility. Property hooks and asymmetric visibility offer new options for managing and controlling property access. With lazy objects, initialization can be deferred, which optimizes resource usage.

A new tool called pie now simplifies extension installation. In addition, BCMath gains extended support through the addition of object types, making even more calculations easier. The historical behaviors of the increment operator on strings and booleans were deprecated in PHP 8.3, paving the way for stricter typing in PHP 9.0.

PHP is also making progress in type handling by introducing null and false as standalone types, while improving union types. Other notable additions include readonly modifications, the ability to fetch dynamic class constants, and support for complex static initializers. These advances reinforce the modernity and robustness of the language.

PHP: The Hidden Engine Behind the Web Giants

PHP is a cornerstone of web development, and many leading companies have adopted it for its performance, flexibility, and reliability. Some of the most emblematic examples:

• WordPress.com, the most widespread hosting platform in the world, is entirely based on PHP.
• Wikipedia, the online encyclopedia, uses PHP (through MediaWiki) to let millions of users read and edit articles.
• Etsy, the online marketplace for handmade and vintage goods, relies on PHP for part of its infrastructure.
• Vimeo, the video platform, uses PHP for its backend.
• Facebook/Meta initially built its platform with PHP before creating Hack, a derived language that runs on HHVM. This historic migration shows the scale PHP can reach.
• MailChimp, a leader in email marketing, uses it for its online solutions.

Beyond the Code: Behind the Scenes of Development

Thanks to multidisciplinary teamwork, issues are triaged and resolved, security reports are handled, code is reviewed, documentation is updated, and infrastructure is maintained. This close collaboration between different profiles guarantees the stability and reliability of PHP.

The past year was full of developments for PHP! Contributions to its repositories jumped by more than 50%, thanks in particular to an external security audit, which is a first. Support for older versions was extended, while the infrastructure was strengthened with new testing and benchmarking tools.

Conclusion

Whether you are an experienced developer or a beginner, PHP offers a playground rich in possibilities. For those who want to dig deeper, the Symfony, Twig, and Sylius certifications (in French) are an excellent way to validate your skills.
