What Is PHP Programming?
Want to learn more about what makes the web run? PHP is a programming language used for server-side web development. If this doesn’t make sense to you, or if you still aren’t quite sure what PHP programming is for, keep reading to learn more.
Understanding PHP
Web development topics can be pretty complicated for people who aren’t at least a little bit familiar with them, so it’s best to start with a simple explanation. In short, PHP is a server-side coding language that uses a format known as scripting. PHP is or has been behind some of the largest web businesses in the world, including Facebook and WordPress.
The Two Sides of Web Programming
The average website or app user doesn’t necessarily think that much about what goes on when they click a button, enter text in a box or scroll through results pages. Just a little bit of typing or clicking and information appears like magic. Of course, it isn’t magic. The clicking, scrolling and typing you do on the visible portion of a webpage is interaction with the website’s front end, or client side. All of the behind-the-scenes communication between different servers to retrieve and display information happens on the back end, or server side. PHP, a back-end language, isn’t about making things look nice the way front-end languages like CSS are.
Other Server-Side Languages
PHP is not the only server-side programming language out there. Others, like Ruby and Python, may be equally or more important in different situations. If you really want to gain an understanding of what PHP does and why, it may make sense to study up on these other languages as well. That doesn’t necessarily mean you need to master all three, but understanding the general function of server-side languages can provide extra context for PHP.
How to Learn PHP
Learning PHP requires some familiarity with how computer code and programming languages work. You can dive right into a free or paid PHP tutorial, but if you aren’t at least a little bit tech literate, you may be out of your depth. Tutorials often recommend that you learn HTML and CSS first. Learning PHP takes time and patience as you’ll need to not only understand the specifics of the language but also the tech jargon that surrounds it.
What Can You Do With PHP?
As a server-side language, PHP can allow you to do a lot of important work on a website’s back end. No, that’s not a double entendre. Back-end development is the process of building the unseen architecture that allows a website or app to function. For example, if you log into your bank account using a secure password, there’s a part of that transaction you see (e.g., the text boxes labelled “username” and “password”) and a part you don’t see, which involves communication of your request to a server, which verifies your username and password, deems them valid and allows you to proceed. All of that unseen communication is a server-side or back-end activity. So if you’re interested in the nitty gritty of what makes the web run rather than worrying about making things look nice and make sense for users, PHP would be a good language to learn. You may also want to learn other server-side languages so you can boost your capabilities and maybe even get a job in the tech industry.

According to Purdue University’s website, the abbreviation for the word “assignment” is ASSG. This is listed as a standard abbreviation within the field of information technology.

Assignment of variables in-template is essentially placing application logic into the presentation that may be better handled in PHP. Use at
