PHP Variable - Introduction

What is Variable?

A variable is a symbol that stands for a value that may vary in the program.

PHP Variable:

Like all programing language, PHP allows us to store bits of data in variable, and then to access that data by writing the variable name in the program. But here you can find that the PHP variable is relatively different then other languages like C and JAVA. In PHP, we do not need to declare the variable type when declaring the variable. It also means that we can change the data type of a variable in PHP as we change the data that the variable contains.
