Is PHP Still Relevant for Business Websites

PHP is still relevant, with most business websites better served by it than by any other server side language. Anyone weighing a rebuild or a platform choice will have heard that PHP is dead, old fashioned or on its way out, yet the usage data and the state of the language tell a different story. For organisations considering PHP development for growing businesses, the more useful question is which version a website runs and whether PHP suits the job in hand.

The sections below set out how widely PHP is used, how far the language has moved on since its reputation was formed and who pays for its development. They also cover where PHP is a good fit, where Python or Next.js make more sense and why an outdated PHP version is a bigger risk than the language itself.

Is PHP Still Relevant

PHP is the most widely used server side language on the web by a wide margin. According to W3Techs, PHP is used by around 70% of all websites whose server side programming language can be identified. The same survey shows close to two thirds of PHP websites now run version 8, while more than a quarter remain on version 7 and close to 8% still run version 5.

That reach comes largely from WordPress, which is written in PHP, along with WooCommerce, Drupal, Joomla and a long tail of custom business applications. The detail behind those numbers, including how W3Techs measures them, is covered in how much of the internet runs on PHP. For decision makers the takeaway is that a PHP website sits on the most common foundation on the web, with a deep pool of developers, hosting and tooling behind it.

Relevance also depends on whether the language is still being improved, which PHP clearly is. A new major or minor version ships every year, older branches are retired on a published timetable and a funded foundation pays developers to work on the core. Those are the signs of a maintained platform, not a legacy one.

Is PHP Dead or a Dying Language

PHP is not dead or dying, although its share of the web is falling slowly. The W3Techs historical trend data shows PHP losing a fraction of a percentage point most months, with JavaScript the main language gaining ground. Ruby, Java and ASP.NET have each held a far smaller share for years.

The “PHP is dead” claim has been repeated for well over a decade. It usually reflects developer fashion more than what is running in production. Newer languages and frameworks get more attention at conferences and on social media, which makes PHP look less popular than it is. A website that was built in PHP ten years ago and is still serving customers today is evidence that the language works, not that it is finished.

A slow decline in share is also different from a decline in use. The web keeps growing, so a language can lose share while the number of websites running it stays very large. What matters to a business is whether PHP will be supported, secure and staffed for the life of its next website. On each of those points the answer is yes.

How Modern PHP Differs From the PHP of 15 Years Ago

Modern PHP is faster, stricter and better organised than the PHP 5 that shaped its reputation. Much of the criticism still aimed at PHP dates from around 2010, when the language had inconsistent function names, weak typing, slow execution and no fixed support timetable. Most of those problems have since been addressed in successive releases.

The first big change came with PHP 7 in 2015. The PHP 7.0.0 release announcement described it as up to twice as fast as PHP 5.6, with significantly reduced memory usage and return and scalar type declarations. For many websites that upgrade alone cut server load and page generation times without any change to the code.

PHP 8.0 followed in 2020 and added a just in time (JIT) compiler, union types, named arguments and attributes. The PHP 8.0 release page is candid about what JIT does. It reports about 3 times better performance on synthetic benchmarks and a 1.5 to 2 times improvement on some long running applications, while typical web application performance is on par with PHP 7.4. JIT helps heavy calculation work, so the everyday speed gains for business websites come mostly from the engine improvements made since PHP 7.

The type system kept improving after that. PHP 8.1 introduced enumerations, readonly properties and fibers. Later versions have continued to tighten how the language handles types and errors. Code written to these standards catches mistakes earlier and is easier for a new developer to pick up.

None of this means every PHP codebase is modern. A website built in 2012 and never refactored will still carry the habits of that era, whatever version it now runs on. The language allows good code. The quality of a particular website depends on how it was built and maintained.

A Predictable Release Schedule With Four Years of Support

PHP now follows a predictable release schedule, with a new version each November and four years of support for every branch. The PHP supported versions page explains that each branch gets two years of active support, with bug and security fixes, followed by two further years of fixes for critical security issues only. When those four years end, the branch reaches end of life and receives no more patches.

The fourth year was added in 2024, when the release cycle update RFC was accepted and extended security support by one year. That change gives organisations more time to plan upgrades, which matters to anyone running a website on a fixed budget cycle. It also means support dates can be written into a roadmap years in advance. The guide to when PHP 8.3 reaches end of life shows how that works for one branch.

The next version is already well advanced. The PHP 8.6 release schedule has the branch in its beta phase now, with general availability planned for 19 November 2026. A language that publishes its timetable this far ahead and keeps to it is about as predictable as open source software gets. The guide to what is changing in PHP 8.6 covers the next release.

Who Funds PHP Development

PHP development is funded by The PHP Foundation, a collective of companies and individuals that rely on the language. The PHP Foundation pays a team of core developers to work on maintenance, security and new features, with new features approved through the community’s RFC voting process. Its founding members include Automattic, the company behind WordPress.com, along with JetBrains, Acquia and the teams behind the Laravel and Symfony frameworks.

The foundation was announced in November 2021. The PHP news archive describes it as an entity for funding the work of developing the PHP language. Before then, much of PHP’s progress depended on a handful of core developers whose employers chose to give them time for it. A single departure could slow the whole language down. The foundation was set up to remove that risk.

For a business choosing a platform, funded and organised maintenance is a reassurance. A language with paid developers, published release schedules and a security process is much less likely to stall than one that depends on volunteers alone.

Where PHP Is a Good Fit

PHP is a good fit for content websites, ecommerce on WooCommerce and business applications that run on a conventional web server. These are the jobs the language was designed for. It handles them with a mature ecosystem, low hosting overheads and a large supply of developers. The full range of uses is set out in what PHP is used for.

Most business websites fall into one of three groups that PHP serves well. Each relies on a server that builds pages from a database, which is the model PHP and WordPress were made for.

Priority Pixels builds websites on a LAMP stack (Linux, Apache, MySQL and PHP) and codes them in custom HTML5, CSS3 and PHP rather than using page builders. That combination keeps hosting simple, avoids lock in to a proprietary platform and leaves the client owning the code. It also means any competent PHP developer can pick the website up later.

Hosting is another practical point in PHP’s favour. Almost every web host supports PHP and MySQL, so a business has a wide choice of providers and is not tied to a single cloud platform. That makes costs easier to control and migration between providers straightforward when contracts come up for renewal.

Where Python or Next.js Fit Better

Python and Next.js fit better when a project is mostly about data processing or an interface that behaves like an application. PHP can do both, but other tools do them with less effort and are better supported for that work. Choosing the right stack for each part of a project is a better approach than forcing one language to do everything.

• Python suits automation, data pipelines, reporting, machine learning and API services that run in the background. Python development for automation and tooling covers the kind of work where Python is the natural choice.
• Next.js suits dashboards, client portals and interactive front ends where pages update without a full reload. It also works as a headless front end, with WordPress still managing the content behind it.
• PHP suits the public website, the CMS and the ecommerce store, which are the parts editors and customers use every day.

Priority Pixels uses Next.js when server side rendering, static generation or a headless setup solves a problem that other approaches cannot. The Next.js development page explains when that trade off is worth making. For many organisations the right answer is a mix, with a PHP website for content and a separate Python or Next.js tool for the specialist job.

What Is Replacing PHP

Nothing is replacing PHP across the board, although JavaScript is taking a growing share of new projects. Frameworks such as Next.js run JavaScript on the server as well as in the browser, which appeals to teams that want one language across the whole stack. Python has also become the default for data science and automation, work PHP was never aimed at.

For content websites, the replacement question rarely holds up. WordPress continues to run on PHP. The plugins, themes and hosting around it all assume a PHP environment. Moving a working content website to another language usually means rebuilding the CMS, the integrations and the editorial workflow, at significant cost and with no gain visitors would notice.

A change of language makes sense when the website’s job has changed. If a marketing website has grown into a product with live data, complex user accounts and an app style interface, a different stack may be the right home for that part of it. If the website still publishes content and generates enquiries, PHP remains a sound choice.

The Real Risk Is an Outdated PHP Version

The real risk for most business websites is running an outdated PHP version, not using PHP itself. Every version up to and including PHP 8.1 has now reached end of life, according to the PHP end of life list. PHP 7.4 lost support on 28 November 2022, PHP 8.0 on 26 November 2023 and PHP 8.1 on 31 December 2025.

Once a branch reaches end of life, newly found vulnerabilities in it are not fixed by the PHP project. A website running PHP 7 or PHP 5 is relying on code that has had no official security patches for years, which is a problem for any organisation that holds customer data or needs to meet security standards in a supplier questionnaire. The same website is also likely to be running outdated plugins and themes, because newer releases often stop supporting old PHP versions.

WordPress makes the same point in its own guidance. The WordPress requirements page recommends PHP 8.3 or greater and warns that older versions which still run WordPress have reached end of life and may expose a website to security vulnerabilities. How WordPress core, plugins and themes behave across PHP versions is covered in WordPress and PHP compatibility.

Upgrading is rarely a single click, which is why many websites fall behind. Each new version removes deprecated functions and tightens rules, so older themes and plugins can throw errors or stop working altogether. The work involves testing on a staging copy, fixing incompatible code and then switching the live server, ideally well before the deadline.

The version a website runs can usually be found in the hosting control panel or the WordPress Site Health screen. If it shows anything older than 8.2, the website is already on an unsupported version and the upgrade should move up the priority list.

Questions to Ask Before a Rebuild or Platform Choice

Before deciding to rebuild, replatform or stay with PHP, it helps to work through a short set of questions about what the website needs to do. The answers usually show whether the issue is the language, the version or the way the website was built.

Working through these questions often shows that a website needs an upgrade and a tidy up rather than a new language. Where the website has outgrown its original build, a rebuild in modern PHP keeps the benefits of the ecosystem while removing years of accumulated problems.

Whether WordPress itself is still the right platform is a related decision. is WordPress still worth it looks at that question for business websites. The answer for most content led organisations is the same as for PHP, with the platform being sound when it is kept current.

Keeping a PHP Website Current

Keeping a PHP website current comes down to regular maintenance, with version upgrades planned around the published support dates. Because PHP announces its end of life dates years ahead, upgrades can be scheduled into a maintenance plan rather than handled as emergencies. Testing each new branch on a staging copy before it reaches the live server keeps disruption to a minimum.

PHP version upgrades sit inside the Priority Pixels WordPress support retainer, alongside database maintenance and prioritised fixes when something breaks. For decision makers, the conclusion is that PHP remains a safe and practical choice for a business website, provided the version is supported and someone is responsible for keeping it that way.
