Title: Hello Variables
Due Date: Sept 3, 2025

Goal

Practice basic PHP variables, concatenation, and simple arithmetic in the command line.

Instructions

Beginner (Full Credit)

Create a file week2.php that:

  1. Defines a string variable with your name (e.g., $name = "Alex";).
  2. Prints a concatenation of "Hello world, " and your variable.
    • Example output:
      Hello world, Alex
  3. Defines two number variables (e.g., $a = 7; $b = 5;).
  4. Prints the sum of those two numbers.
    • Example output:
      The sum of 7 and 5 is 12

Advanced (Optional)

Add one of the following for practice:

  • Store your variables in an array and loop through them to print values.
  • Use an associative array with keys like "name" or "age" and print them.
