How to create and use variables in PHP

Variables are used in PHP to store and manipulate values. They can be defined by using the “$” sign followed by a name of your choice.


      $variable_name = value;

Usage Examples:

Example 1: Declaring a string variable

      $name = "John";
      echo "My name is $name";

Example 2: Declaring a numerical variable

      $age = 25;
      $new_age = $age + 5;
      echo "My age is $new_age";

Parameter Values:

Parameter Description
$variable_name Name of the variable you want to declare
value The value you want to assign to the variable

Technical Details:

PHP variables are case-sensitive, which means that $name, $Name, and $NAME are three different variables. Additionally, PHP has several data types that can be assigned to a variable:

  • String
  • Integer
  • Float
  • Boolean
  • Array
  • Object
  • NULL

For more information on PHP variables and data types, see the PHP manual here.
