Everything you need to know about PHP 8

You may have noticed that several hosting companies that offer web hosting have started advertising that you can use PHP 8 with them. But is PHP 8 something you should be aware of, and what impact could it have on your website?

There may be several good reasons to update your WordPress or Joomla site to use PHP 8.0. Among other things, it helps to increase the speed of your website. In this blog post, we dive into what else the new PHP update will mean for your website.

What is PHP?

PHP is an open source programming language consisting of “server-side scripting”, which is widely used for web development. PHP is an important language for the WordPress community because much of the core WordPress software is written in it.

According to W3 Techs, PHP is used by 77.5% of all websites worldwide. Even if you’re not a programmer, if you have your own website, you’re probably using PHP. If your website is made in WordPress or Joomla, these are two systems that use PHP.

What is the difference between PHP 7 and PHP 8?

At first glance, the difference between PHP 7 and PHP 8 is not very big. Certainly not if you are not a programmer and are familiar with the many features that have been added.

The function and task of PHP itself is the same in PHP 8.0 as it has been in the previous PHP versions. Where you as a regular user will primarily notice a difference will be the speed of your site. Among other things, the new PHP version 8 comes with a number of optimizations to the way your site handles requests.

FACTS – What does request mean?

When you visit a website, your PC or mobile executes a request to the website’s web server. A request is the communication between your browser and a web server that provides the user with the requested page and its content.

When a web server receives a request from a client (such as a PC or mobile), it will retrieve the requested material and display it on the user’s screen. Each time a request is made from the client, the server executes each request, resulting in the requested page, images or interactive features being loaded.

Will my website be faster if I update to PHP 8?

The loading time of a WordPress website is one of the things that PHP 8.0 noticeably improves and optimizes. The amount of requests that PHP 8 can handle is higher than in the previous versions. The faster your site can handle a request, the faster your visitors will be able to load your site.

On a new WordPress installation with PHP 7.4, the site can handle 110.24 req/sec. In comparison, PHP 8.1 can handle 163.43 req/sec. This means that PHP 8.1 is about 50% faster.
