PHP Variables

Variables are containers used for storing information.

Creating Variables

Remember that PHP variable names are case-sensitive!.

Rules for creating PHP variables:

  • A variable starts with the $ sign, followed by the name of the variable
  • A variable name must start with a letter or the underscore character
  • A variable name cannot start with a number
  • A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
  • Variable names are case-sensitive ($age and $AGE are two different variables)

 

 

Note: Unlike other programming languages, PHP do not need to be declared with any particular type, and can even change type after they have been set. Creating and Declaring are done at a same time.
