About Lesson

A Variable is a holder used to store both numeric and non-numeric data.


Rules for Variable declaration

  • In PHP, the variable starts with a dollar($) sign, succeeded by the name of the variable.
  • In PHP, a variable name must start with a letter or the underscore character.
  • In PHP, a variable name only contains alpha-numeric characters and underscores (A-Z,a-z, 0-9, and _).
  • A variable name must not contain space.


Assigning Values to Variables

$name = "infovistar";
echo $name;

Example (Addition of two numbers):

$a = 10;
$b = 15;
$c = $a + $b;
echo $c;
