PHP Tutorials – How To Declare Variables in PHP


Variables are like containers for storing information. In PHP a variable is declared by prepending a dollar ($) to the variable name. Unlike other programming languages, PHP has no command for declaring a variable – the variable is created the moment you first assign a value to it.

A variable name must either begin with a letter or the underscore character but it cannot start with a number. Besides, a variable name can only contain alphanumeric characters and the underscore.

Declaring a variable is a statement in PHP and so we have to terminate it with a semicolon.
