Understanding PHP and Its Versions: A Guide for Beginners
At Ffon Host, we know that choosing the right hosting environment can seem overwhelming, especially with all the technical jargon that comes with it. One term you may often see is “PHP.” But what exactly is PHP, and why are there different versions of it? Let’s break it down so that you can make more informed decisions about your hosting setup.
What is PHP?
PHP, or Hypertext Preprocessor, is an open-source scripting language specifically designed for web development. It runs on the server side, meaning it’s executed on the web server before the page is sent to the user’s browser. PHP allows developers to create dynamic, interactive websites, making it possible to build everything from simple blogs to complex online stores.
One of the primary benefits of PHP is its versatility and ease of use. It can integrate with various databases, like MySQL, and works well with HTML and CSS. PHP is also highly flexible and has a large, supportive community, so resources and troubleshooting help are abundant. With over 75% of websites using PHP in one form or another, it’s the language behind many popular platforms, including WordPress, Drupal, and Joomla.
A Brief History of PHP Versions
Since its release in 1995, PHP has evolved significantly, with each new version adding features, fixing bugs, and enhancing performance. Here’s an overview of PHP versions and how they differ:
1. PHP 5.x Series
PHP 5, released in 2004, was a major leap forward, introducing object-oriented programming (OOP) features and improved support for MySQL. It was one of the most widely adopted versions for years, making PHP a serious language for large-scale applications. However, PHP 5 reached its end of life in December 2018, meaning it no longer receives security updates. If you’re still using PHP 5, it’s time to upgrade for better performance and security.
2. PHP 7.x Series
After PHP 6 was skipped, PHP 7 was introduced in 2015. This was a game-changer for PHP as it delivered a significant boost in performance and efficiency, executing code up to twice as fast as PHP 5.6. It also introduced new features like the null coalescing operator, spaceship operator, and scalar type declarations. PHP 7.4, the last version in the series, added more improvements like typed properties and arrow functions, making code more concise and readable. Many websites today still rely on PHP 7, but it’s also reaching its end of life, so it’s worth upgrading.
3. PHP 8.x Series
PHP 8.0, released in November 2020, continued to push PHP forward with enhanced performance and new language features. The standout additions include the Just-in-Time (JIT) compiler, which boosts performance for heavy computations, and Union Types, which add more flexibility in type declarations. PHP 8.1 and PHP 8.2 have further refined these capabilities, making PHP more powerful and versatile than ever.
Here are some of the key features of PHP 8 that set it apart:
- JIT Compiler: Improves performance by compiling parts of the code at runtime.
- Union Types: Allows specifying multiple types for a single variable.
- Attributes: Annotations that add metadata to code, improving extensibility.
- Named Arguments: Allows passing function arguments by their names rather than their order.
As PHP 8 is the most modern version, it’s highly recommended for anyone looking to build a fast, scalable website.
Why PHP Versions Matter
PHP versions impact website performance, security, and compatibility with other software. Each version has a designated support lifespan. If a version has reached its end of life, it no longer receives security updates, making your website vulnerable to threats. Additionally, certain plugins and themes may require a specific PHP version to work correctly, so using an outdated version could mean you’re missing out on new functionality or support.
Which PHP Version Should You Choose?
For most users, we recommend using PHP 8.0 or higher. The speed and features of PHP 8 will provide your site with a noticeable performance boost and make it future-proof for the years to come. However, some older sites or CMS platforms may still rely on PHP 7.4. At Ffon Host, we offer flexible PHP version management across our hosting plans, allowing you to choose the version that best suits your needs.

PHP is a powerful tool for creating dynamic websites, and its evolution over the years has only made it stronger.
