An Introduction to PHP

PHP is an underlying scripting and programming language that plays a significant part in WordPress development (mainly). PHP retrieves information from databases and transforms the data into an HTML website page each time you have a visitor to your site.

If you’re a webmaster, you may not have to master PHP programming. After downloading WordPress, you’ll receive all your PHP files that comprise WordPress.

While these files were designed for you and are awaiting your content, themes and plugins, there are a few scenarios in which you could benefit from the editing of PHP files:

  •     The creation of a custom theme or plugin
  •     Modifying the files on your server
  •     Connecting a site to a MySQL database

Because PHP is among the primary languages used in WordPress, knowing an understanding of how to use it can broaden the possibilities of what you can work on.

Most likely, you won’t be required to edit any of your PHP files. However, understanding PHP can be useful for developers looking to develop new software or modify existing ones. Now, why do you need to upgrade to PHP 8.2?

PHP 7 allows the system to run more than twice the number of requests per second, compared to PHP 5.6, which runs at nearly half the latency.

A lot of times, the designers of themes and plugins cannot extend support for earlier versions. The reason for this reason, is time-related and not having the time to check compatibility.
