PHP Variable

A variable is a container for storing data for use in a program.

The simplest way to store information in PHP is through variables. Variables can be stored in two ways: A string or an integer.

A string is any sequence of characters enclosed in single or double quotes, e.g., 'Hello' or "World". They are often used to store text but may also contain numbers, special characters and even other strings (although this is not recommended). Strings are typically used to represent text that people can read.

An integer is any whole number without a fractional component, e.g., 10 or -32000. They are often used to store numbers, but can also contain decimals when necessary (e.g., 7.5).
