Variables
In PHP, variables are used to store and manipulate data. A variable is defined using the “$” symbol followed by a name, and it can hold a variety of data types such as integers, floats, strings, booleans, and arrays. Variables in PHP are loosely typed, meaning that the data type of a variable is determined at runtime based on the value assigned to it. Variables in PHP are also case-sensitive, which means that “$myVariable” and “$MyVariable” are two different variables. Variables in PHP can be passed between functions and can have a scope that determines where they can be accessed within a script.
