What’s new in PHP 8? →

For those who don’t know, WordPress run on PHP on the server. This has been true for all of WordPress’s life, and remains so. For the most parts, this dependence on the PHP language has been an interesting tidbit. But in the next few weeks the next major version of PHP is coming out, and it’ll have a big impact.

In a “major version” release, backwards compatibility is often not guaranteed. More than not-guaranteed, I’d even say that “breaking backwards compatibility” is usually the *reason* for a major version release. (WordPress generally doesn’t do semantic versioning, and so this system doesn’t apply quite the same in WordPress itself or its plugins/themes ecosystem as it does for PHP and most other programming-things.)

Anyway, for those of us trotting along behind, it’s good to keep some sense of what’s happening in the new version of PHP. That is precisely what I think this article from Brent Roos does a good job of: quickly moving through the big features and giving you a taste of what’s to come. Check it out!

What is PHP and Why it is Used?

What is PHP and Why it is Used?

PHP is a server-side scripting language used for the development of web applications, dynamic websites and static websites. PHP was originally an abbreviation for “personal home pages” but has since been changed to “hypertext pre-processor.”

In this guide, we’ll cover more about what is PHP and the basics of PHP. Let’s dive in.

Basics of PHP & Server-Side Scripting

In order to interpret PHP scripts, PHP must be installed on your server. As a server-side language, you use PHP for local website activity on your computer through your web browser.

A web browser is required to access PHP scripts. Server-side activity is when requests are sent by your web browser to the server. Your browser will receive instructions from JavaScript, CSS or HTML for translating the content appearing on your screen. These instructions are then executed by your web browser.

Your web server uses hardware or software to send requests to the server. Your request will generate HTML code processed by your browser prior to appearing as content on your screen.

Your web servers stores your content as:

  • Website pages
  • Media
  • Images
  • Other assets

The difference is your communication with the server is not entirely completed within your browser. The key difference with a scripting language is tasks are automated using the content available within your web browser. You use PHP for requesting content with your website database or server. Your content will be both accessible and visible.

Website efficiency is maintained by consistently storing your local assets on web pages including storage capacity and loading speed. You can use PHP script to ensure your three most current blog posts automatically appear on the front page of your website. Your posts will be stored by your server, then retrieved when occupying any of your three most currently published slots.

The idea is to eliminate the necessity of preloading your posts and loading and updating your posts every time you publish new content. You can also use PHP for directing conditional statements to add content or change your display by using your web server whenever necessary. You can select specific actions such as using an x field to upload video links.

Your server then loads your video for display. You can even state if you do not upload a link, an image of the Y default will appear instead. An entirely new level of possibilities is introduced by the server-side actions of the PHP in addition to the static features provided by CSS and HTML. JavaScript will enable your dynamic content.

PHP File Extension

PHP files include PHP tags concluding with the .php extension.

When browsing your website’s files, you’ll see PHP files in the list.
