PHP Variables

18 May 2009 / 4 Comments

Like most programming languages, PHP lets you create variables in your scripts. A variable is a storage container that holds a value. This value can change as the script runs. You can:

  • Assign any value you like to a variable
  • Access the value stored in a variable, and
  • Change a variable’s value at any time.

Variables are useful because they let you write flexible scripts. For example, a script that can only add 3 and 4 together isn’t very useful. A script that can add any two values together, though, is much more flexible.
