PHP Variables

-
  In PHP, a variable starts with the  $  sign, followed by the name of the variable: for example: <?php $txt =  "Hello RK!" ; $x =  5 ; $y =  10.5 ; ?> A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for 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: Remember that PHP variable names are case-sensitive! Output The PHP  echo  statement is often used to output data to the screen.
