Variables are containers that store data.
PHP is a programming language that is used to create web pages with dynamic content. Variables are containers with data in them, which you can use for different purposes, like storing the name of the user who is browsing your website or how many times someone has viewed your website.
Variables in PHP work similarly to variables in most other programming languages. There are two types of variables in PHP - scalar and array.
Scalar is simply a container that stores one value at a time, while arrays can store multiple values at the same time.
