What is an Array?

In WordPress code, the array () function allows one variable to hold multiple data points, such as a list. It can help developers create more efficient code.

More About Arrays

The array () function is a part of the Hypertext Preprocessor (PHP) coding language. This is one of the most common programming languages used in WordPress, along with CSS, HTML, and Javascript.

When the array () function is used to organize data, it can be easier to retrieve information later on. For instance, when a list is represented by one variable instead of its individual elements, it can later be fetched as a whole.

Other operations can also be performed more easily when theme, core, and plugin files are built using the array () function. Furthermore, there are three types of arrays: indexed, associative, and multidimensional.
