What is PHP? It is a programming language used to create interactive and dynamic websites. It is an open-source scripting language adopted by popular platforms such as WordPress.
PHP operates on the server through your web host, allowing it to run in the background to be accessed at any time. Viewers will see the HTML page it produces but not the script itself.
The purpose of the PHP language is to create dynamic web pages and to power the back end of a WordPress website.
What is PHP and how does it create dynamic web pages?
PHP is a script that allows you to interact with files stored in the server. PHP can write, open, create, read and close files, to name a few. It also allows you to add or remove data as needed, making it easy to update page content. A common example of what PHP is used for is to run the WordPress website engine. It uses PHP to execute all its scripts and mechanisms.
However, a web browser cannot view PHP files directly, as it can only work with HTML. The reason PHP works is because of the communication between the web host and the browser. Once someone enters your website, they will send a request to the web host. The host would then use PHP to write the HTML code, which they would send back to the browser. The browser interprets this code and turns it into a web page that you can view and use.
How does PHP power the back end of a WordPress website?
All WordPress websites use PHP as a foundation. The WordPress web host accesses the data stored in the PHP code to supply the HTML code. The good news is that you don’t need to learn how to code PHP in order to use or manage a WordPress website.
WordPress makes customization easy by allowing users to adapt themes or plugins to these websites. These themes and plugins contain code that automatically executes a script that changes your website. For example, you can place the following on your website via plugins:
- Almanac
- request/contact form
- data tracker
- Links to Other Web Sites
- and many more
However, those looking to customize their WordPress website may want to learn PHP as the language allows them to implement their own unique vision. The alternative is to hire a professional to code for you, but this may mean additional expense.
Should we use php?
PHP is one of the most flexible programming languages available, which is why it has been used by WordPress websites for 15+ years. This language can work on all platforms, is fully customizable, and easy to pick up. Thanks to PHP’s versatility and compatibility, it works for everyone who browses online. The fact that it remains the primary language used by WordPress shows how powerful it is.
PHP receives regular updates that improve loading speed. This scalability gives you the means to build any website you want, as well as the ability to interact and work with many different types of files.
